SGP/EBBR/E13 - failure of sensors
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.00, sgp5ebbrE13.a0
Description:
A lightning strike to the central cluster area shortly after 0800 GMT
on July 17 caused failure of several EBBR sensors: both humidity probes,
the barometer, soil heat flux #3, soil moisture # 1 and the wind
direction.
These failed sensors caused sensible, latent, and average soil heat flux
to be incorrect until site operations performed maintenance on July 24th.

Site Operations found a loose connection from soil moisture probe #1, 
removed barometer SN 6578 and replaced it with SN 6507, removed soil heat 
flux sensor #3 with SN 923022 and replaced it with SN 933199, repositioned 
the wind direction sensor - which was rotated approximately ninety degrees 
clockwise from its proper position, and removed the right humidity probe 
SN 460412 and replaced it with SN 460428.

SGP/EBBR/E13 - Failed Right Humidity Probe
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.00, sgp5ebbrE13.a0
Description:
A lightning strike to the central cluster area on 17 July 1995 caused
failure of several EBBR sensors including the right humidity probe.
On July 24th, site operations removed the right humidity probe SN 460412 and 
replaced it with SN 460428

In less than a day the right humidity probe output soared to over 113% and
has hovered around 112% since.  I consider all right probe values to be
incorrect due to this behavior.

Without a properly functioning right humidity probe, all values of top and
bottom relative humidity, top and bottom vapor pressure, Bowen
ratio, and latent and sensible heat fluxes are incorrect.

A working spare relative humidity probe was not available at that time.
The probe was replaced with a working, calibrated probe on 22 September 1995
at about 2108 GMT.  I have the examined the data since the day of the
replacement and find that the new probe is working well.  All E13 EBBR
measurements are presently correct.  The old probe S/N was 460428, the new
S/N is 460413.

Description:
Soil Temperature #4 produced noisy measurements, resulting in quantities
calculated from it to be of suspect quality.  This condition normally 
occurred early in the GMT day.  Sensible (h) and latent (e) heat fluxes
were not normally greatly affected.  Average surface heat flow was normally
slightly underestimated.

DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1
Description:
Soil Temperature #4 floated around, causing average soil heat flow
to sometimes be too small (resulting too small a sensible heat flux and
too large a latent heat flux) or too large (resulting in too large a 
sensible heat flux and too small a latent heat flux).  Investigation of
g4 will indicate when these conditions occurred and the likely effect on
sensible and latent heat fluxes.

SGP EBBR E13 - E13 EBBR AEM Home 30 Offset or AEM in Mid Position
DataStreams:sgp15ebbrE13.a1, sgp15ebbrE13.b1, sgp30ebbrE13.a1, sgp30ebbrE13.b1, sgp5ebbrE13.a1
Description:
The AEM stopped before reaching the end of it's travel,
causing the home signals to be between 0 and 3 during 
part of this period.

The AEM home30 signal is offset by approximately 25 
during part of this period; it appears that the electronics 
of the AEM is adding the home15 and home30 voltages 
together when the AEM is in the home30 position.

All gradient data, sensible heat flux, latent heat flux,
and the Bowen ratio are incorrect during these conditions.

SGP EBBR E13 - E13 EBBR Left Air Temperature Incorrect
DataStreams:sgp15ebbrE13.a1, sgp15ebbrE13.b1, sgp30ebbrE13.a1, sgp30ebbrE13.b1, sgp5ebbrE13.a1
Description:
This condition occurred most of the time during the 
indicated period (hence color yellow).

The left air temperature was incorrect only when the AEM
was in the home 30 position.  This only affected the bottom
air temperature calculation.  However, it made the latent
heat flux, sensible heat flux, and Bowen ratio incorrect.

The sensor was improperly inserted into the aspirator shield
and was pinched between the shield and the T/RH probe. When
the AEM was in the home30 position, the aspirator hose
position may have caused the sensor to short to ground.

Description:
Soil Temperature #4 was often incorrect, typically too large negative,
during this period, causing other measurements calculated with
it to be incorrect also. This was caused by a bad multiplexor channel,
which was discovered by the vendor during recalibration of the unit
later.

Description:
During much of the indicated period the Left T/RH Temperature was
incorrect.  Because the home signal was between 0 and 3, the 
temperature was incorrect when the AEM was at the bottom position,
but was correct when the AEM was at the top position.  This was caused by
a short created when the sensor was mispositioned in the aspirator
housing and enough strain on the cable for it to bring it into contact
with the housing in the bottom position.

SGP/EBBR/E13 - T/RH Check
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
During the month of November 1994, site operations personnel conducted
field comparisons of the temperature and relative humidity sensors in the
EBBRs and the HMI31 portable T/RH meter (with the removable probe).  As is
reflected in the home signal output, the automatic exchange mechanism was
disabled in order to conduct the checks.

Measurements were taken every 5 minutes, for a half hour each in the
aspirated radiation shields (the HMI31 was inserted into the EBBR aspirated
radiation shield to provide the same aspiration as the EBBR sensors
received).  Measurements of aspirator flow were also recorded.  This
information was provided to the mentor.  The mentor then compared the field
checks with the data recorded by the EBBRs.

The periods of data and data fields that are incorrect because of the checks
are listed below.  Times are those at which the data are reported.


Data Fields
5 minute:  tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
           vp_top, vp_bot

30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
           vp_top, vp_bot, bowen, e, h

           2050, 2055, 2100, 2105
15 minute: 2015, 2045, 2100, 2115
30 minute: 2030, 2100

(EDITOR'S NOTE:  The following analysis refers to all EBBRs installed in Nov 1994)

Results of the T/RH comparisons:
The combined accuracy of the HMI31 and EBBR temperature sensors
(thermocouples or PRTDs) is +/- 0.4 degrees C.  The combined accuracy of the
HMI31 and EBBR RH sensors is +/- 4% for RH less than 80%, and +/- 6% for RH
greater than 80%.  The combined accuracy for each pair of EBBR sensors of
the same type is essentially the same as the quantities stated above.

All of the pairs of EBBR sensors show differences that fall within the
stated combined accuracies.  Although this sounds wonderful, a few of the
differences are close to the combined accuracy, which, because of the small
differences in temperature being measured (normally smaller than the
magnitude of the combined accuracy) could lead to some incorrect estimation
of sensible and latent heat flux.  However, unless there would be substantial
differences of calibration slope of two sensors in a pair, the switching of
height of the sensors every 15 minutes by the automatic exchange mechanism
will remove the offset between the sensors.

The comparisons between the EBBR sensors and the HMI31 T/RH meter showed
much larger differences.  The range of differences were: -2.4 to 0.0 degrees
for the thermocouples, -2.1 to 0.1 degrees for the RH probe PRTDs, and -6.6 to
6.7 percent for the RH sensors.  Six Thermocouples indicated differences from
the HMI31 greater than the combined accuracy.  Seven PRTDs indicated
differences from the HMI31 greater than the combined accuracy.  Four RH
sensors indicated differences from the HMI31 greater than the combined
accuracy.  The temperature differences (for both thermocouples and PRTDs)
were nearly all of one sign; the HMI31 indicated the greater temperature,
which may suggest a bias in the HMI31 temperature measurement, even though
a dozen differences of +/- 0.2 degrees were measured.  Four differences of
zero and only one positive difference (out of 40) were measured.  Thirteen of
the 20 RH differences were positive (HMI31 indicating the lower
RH), with the differences near the level of the combined accuracies being
approximately 50% positive and 50% negative.  It does not appear that the
HMI31 has a RH bias.

Plots of EBBR sensor/HMI31 differences as a function of time from the
installation of the individual sensors (a range of 10 to 30 months in the
field) shows no obvious pattern of sensor drift with time.  This is encouraging.

SGP/EBBR/E13 - 3-month Check
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
During EBBR 3 month checks the Automatic Exchange Mechanism is disabled
(reflected by home signals near zero) so that the two aspirator units can be
placed at the same height.  The measurements during this period, at least,
do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h),
or latent heat flux (e), nor do the air temperature and relative humidity
measurements indicate gradients.  Checks performed before or after the AEM
is disabled also lead to some incorrect data.

Time of the check is not known, so the entire day has been flagged as
suspect.

Description:
The automatic exchange mechanism hung numerous times, but with various different 
measurements of home signals.  In all cases, temperature and humidity gradients were incorrect; 
thus the Bowen ratio, sensible heat flux, and latent heat flux are incorrect for the 
indicated periods.  Even when the home 15 and 30 signals were different (but too high) the 
measurements were incorrect because the program keys off of the home signals, which must be 
in the proper ranges.

SGP/EBBR/E13 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE13.b1
Description:
Effective 20050331.2100, the EBBR.E13 CR10 program was revised to improve the quality of 
the primary measurements as follows:

1) An RMS procedure is used to determine max and min limits of acceptable soil heat flow.  
This is applied to the individual soil sets.  Measurements outside the limits are 
rejected and the measurements within the limits are used to calculate the average soil heat flow.

2) Max and min limits are used to determine incorrect values of net radiation, sensible 
heat flux (h), latent heat flux (e), and automatic exchange mechanism (AEM) signal.  If AEM 
signal is outside the limits, h and e are set to 999s.  If net radiation is outside the 
limits, h and e are set to 999s. If h or e are outside the limits, h and e are set to 999s.

Virtually no incorrect soil measurement will affect the primary measurements of h and e.

By setting h and e to 999s, it can be easily seen that the primary variables are 
incorrect; no other interpretation is possible.

Prior to 20050331, the improved CR10 program was NOT in effect.  DQRs have been submitted 
for known instances of incorrect soil measurements which affected the quality of the 
primary measurements of h and e.

Note: the DQR begin date is the begin date of the sgp30ebbrE13.b1 data stream.  The 
earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. 
sgp30ebbrE13.a1).

SGP/EBBR/E13 - Radiometer dome broken
DataStreams:sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:
The top net radiometer dome was broken, yielding net radiation, sensible heat flux and 
latent heat flux that were too low.

The BEFLUX (SIRS) net radiation can be used as a replacement for the EBBR net radiation.

To correct the sensible and latent heat fluxes, determine the ratio of SIRS net radiation 
to EBBR net radiation for each daylight half hour and multiply that ratio times H and LE 
to obtain approximate corrected flux values.

SGP/EBBR/E13 - incorrect home signal
DataStreams:sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
EDITOR'S NOTE:  This DQR refers to data collected by the EBBR at E13 prior
to the begin date of regular ARM data.  At that time, the data streams which
contain the EBBR.E13 data were named 
      Dsgp15ebbr1.a0
      Dsgp30ebbr1.a1
      Dsgp5ebbr1.a0
These data are not readily available from the ARM archive, but can be
made available by special request.  The actual time range of the problem
described here is 921230.0000-930423.1200.



EBBR1, Central Facility reported incorrect home value signals from 30
December 1992 through 23 April 1993.  The home signals are used in the
calculation of fluxes by the CR10 data logger.  The fluxes for this period
are thus invalid as reported and must be recalculated from the archived 15
minute data.  The proper home signals are less than 35 for 30 minute home
signal and greater than 35 for 15 minute home signal.  Home signals were
the same value for 15 minute and 30 minute during the period of interest,
although they were not a constant value.  The chronology of the situation
is reported below.  On 7 April 1993 I noticed the problem in the A0 data.

On 30 December 1992, the automatic exchange mechanism (AEM) of the Central
Facility EBBR froze up with ice and stopped working (surmised from looking
at the EBBR1 data).  This caused a fuse to blow and stop the mechanism from
operating.  However, one channel of the CR10 data logger was apparently damaged
in the process.  The condition of the AEM only, was noticed on 4 January 1993
by site operations personnel.  The blown fuse was replaced, which started
the AEM working; but AEM home signal values between 30 Dec and 04 Jan were
around zero.  Home values remained around zero until at least January 8, 1993.
I have a gap in data archived at ANL between 8 and 15 January 1993, during
which I do not know quite what was happening.  On 11 January 1993 site
operations personnel found that the EBBR1 battery was run down and the EBBR
thus was not working.  A new battery was installed.  On 15 January the home
values were about 34.  I am assuming that they became 34 upon installation
of the new battery on 11 January.  Until at least 15 January the home signals
stayed around 34.  After that period the home signals became greater than
35 and generally were around 36.  Only occasionally (a few hours here and
there)were the home signals just above or below 35 to produce the proper
flux outputs.  On 23 April 1993, at my direction (and after a week of tests
on other parts of the system), the CR10 data logger was replaced.  This solved
the problem.  In fact, previous to this I had suggested reloading the software
into the previous CR10, but the CR10 would not accept it; as soon as the
machine was deactivated before that procedure it stopped working altogether.
I find it amazing that it worked at all, although all data other than the home
signals, and the calculated quantities dependent on them looked perfectly
acceptable during the period of interest; there is no evidence that the
CR10 was malfunctioning in other areas.

The road to restoring the 30 Dec to 23 April data would be a rocky one, as
each 15 minute data period would have to be examined to determine the
proper position of the sensors on the AEM.  However, it is possible to
reconstruct most of the 30 minute calculated values from the 15 minute data.

SGP/EBBR/E13 - incorrect meteorological observations
DataStreams:sgp30ebbrE13.a1, sgp5ebbrE13.a0

EDITOR'S NOTE:  This DQR refers ti data collected by the EBBR at E13 prior

These data are not readily available from the ARM archive, but can be

described here is 930417.1200-930422.1730.


Beginning at 1200 UTC on 17 April 1993, EBBR1, Central Facility, outputs
ramped to extreme values, some positive, some negative.  These outputs ended
their ramping approximately 3 hours later.  Comparison with SMOS data
indicate that no time averaged outputs from EBBR1 were consistent with the
SMOS after 1200 UTC.

It appears that the averaging instruction in the CR10 data logger had been
corrupted.  On 22 April site operations, at my request, tried to reenter
the software; this attempt was completely unsuccessful, indicating that the
CR10 probably had other problems as well.  EBBR1 was offline from 1730 UTC
on 22 April until 1400 UTC on 23 April, when a new CR10 was installed and the
software downloaded successfully.

Since a SDS utility for extracting real time data from the CF SMOS had not been
established, EBBR1 was being used for weather observations.  All EBBR1
measurements of meteorological quantities during the period above are
invalid.

SGP/EBBR/E13 - pressure calibration
DataStreams:sgp30ebbrE13.a1
Description:
In the original Campbell CR10 software provided by the vendor (version 1),
the EBBR had incorrect calibration pressure sensor slopes and offsets.
The slopes and offset was carried through into version 2 of the
software and was not discovered by the mentor (me) until sometime later.
The calibration and slope did not deleteriously affect calculations in
the program since only a four percent reduction in atmospheric pressure
measurement resulted (the calculations are not very sensitive to small
errors in pressure). The vendor does not recall how the wrong
calibrations came to be used.   

Version 4 of the CR10 program includes the proper calibration and offset. 
This remedies the apparent offset problem (it was actually a calibration 
and offset problem). In comparisons with the co-located SMOS pressure
sensor, the difference between the SMOS and EBBR pressure values appeared
almost constant with time, hence the assumption of an offset problem.
However, the EBBR pressure sensor offsets are so large (a consequence of
tailoring the calibration curve to a small range of elevations in which the
calibration applies) that the very small error in slope was difficult to
recognize.

The outputted pressure values for the EBBR system can be corrected
with the following information and equations.  

         Old Slope     Old Offset        New Slope     New Offset

          0.01952        81.24            0.02031        81.27

   Correct Pressure =
               ((Current Pressure Data - 81.24)*0.02031/0.01952) + 81.27
                    =  1.04047*(Current Pressure Data) - 3.258

SGP/EBBR/E13 - solid moisture correction
DataStreams:sgp30ebbrE13.a1
Description:
In the original EBBR software (Version 1) for the Campbell CR10 at the Central
Facility (E13), adjustment of the soil moisture for soil type was performed
differently than for the other EBBR systems.  This was supposed to have
been changed prior to installation (according to the vendor), but the
change was not made.  This adjustment was carried into Version 2 and was
not discovered by the mentor (me) until later.  A polynomial is used to
adjust the measured soil moisture for differences between the soil type at
the location of installation (clay-loam assumed) and the soil type (sand)
used in the calibration of the soil moisture sensor.  The adjustment in
the E13 EBBR only, was computed on the basis of a sandy-loam soil.

Presently, a clay-loam soil type is assumed for each EBBR location.  Soil
types at the extended facilities have not been characterized yet, although
there are hopes of doing so in the future.  The effect of using a
polynomial for sandy-loam soil instead of clay-loam soil is to decrease the
resultant soil moisture values by approximately 14.5% when the clay-loam
polynomial would indicate a soil moisture of 28.3%, and by approximately
38.3% when the clay-loam polynomial would indicate a soil moisture of 6.3%.
The normal range of soil moisture at the EBBR sites is approximately 3% to
35%.

The effect of the soil moisture decreases above on the adjustment to soil heat
flux plate measurements is less than 1.0%.  The effect on the change in
energy storage in the soil (determined from the change in soil temperature
over time) is a 10% decrease for a soil moisture of 28.3% and a decrease of
13.0% for a soil moisture of 6.3%.  The change in energy storage is typically
5% of the total surface energy budget during mid-day and 25% at night.
Therefore, the soil type adjustment error in the Central Facility EBBR
resulted in approximately a 0.5% error in the surface energy budget during
mid-day and 2.5% at night.  These are small and acceptable errors and
should not cause one to need to recalculate energy budget values.

SGP/EBBR/E13 - SM4 Replacement
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1
Description:
Soil Moisture Probe #4 has been indicating large soil moistures in the past
couple of months.  At times the values have exceeded the upper limit of the
acceptable range.  This data could be considered questionable, although the
affect on average soil moisture and quantities affected by it is very small.
Therefore, I do not suggest additional flagging of the data other than that
imposed by the limits.  The probe was changed from S/N 92004 to 93004 on
May 6, 1994 at 1530 GMT.  During the exchange process a few selected periods
of soil moisture #4 data is incorrect, but not so different from the other
soil moisture probes as to have a significant affect on the average soil
moisture or the fluxes.

Additionally, the EBBR output was interrupted for a half hour while the
calibration of the new probe was entered into the CR10 data logger.
Therefore, all 5 minute data from 1535 to 1600 GMT, 15 minute data for 1545
and 1600 GMT, and 30 minute data for 1600 GMT is incorrect.

Furthermore, disturbance of the area near the #4 soil probes (temperature,
soil moisture, and heat flux) caused all three to be incorrect for the
following periods:

30 minute  1530 GMT

Complete recovery by all three sensors did not occur for one day (which is
fairly typical for near surface installations), although the differences
from the other four sets of soil sensors did not deleteriously affect the
averages of the soil quantities.

Description:
For a period of not quite a day, soil temperature probe #4 indicated values
that were either too high or too low, for unknown reasons.  After Site
Operations personnel checked connectors and the probe itself, it recovered
to proper values.  The probe has functioned properly since then.  The times

For periods of a number of days in December 1994, soil temperature probe #4
indicated incorrect values that were either too high or too low.  Site
Operations personnel replaced the sensor on December 30, 1994.  The times
and incorrect data fields are listed below.  Only half hour times are
listed.  The incorrect data on December 30 was the result of the process of
replacing the sensor during that time.

Recomputation of the change in energy storage in the soil could be done
roughly from the soil temperature sensors that were still working (roughly
because the difference in soil temperature with time is determined with
real-time (one minute samples) data, not from the 15 or 30 minute data).
However, this would require considerable effort.  The process for doing so
is therefore not stated here.  Contact the mentor for more information if
neccesary.

SGP/EBBR/E13 - Low Battery Voltage and AEM Left on Manual
DataStreams:sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
Low battery voltage caused some data values to be incorrect beginning at
1500 GMT on August 1, 1995.  The data should be carefully inspected to
determine which values are incorrect.

During replacement of the battery at the Central Facility EBBR on August
1, 1995, the AEM exchange toggle switch was left in the manual position,
which caused the right aspirator to remain in the home position until the
switch was correctly placed in the exchange position at 1616 GMT on August
2, 1995.  All 5, 15, and 30 minute values of temperature, relative humidity
, vapor pressure, bowen, e, and h are incorrect during the period. 15 and

SGP/EBBR/E13 - Battery Voltage Drop
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
Sometime before August 16, 1995 the AC/DC converter was switched off and
the instrument heaters were switched on.  The solar panel was not able to
keep the battery voltage up under these conditions.  Much of the data for
the periods indicated is incorrect, especially data from the sensors that
require 12 volts DC power.  The data would have to be inspected to
determine what data is correct and what is incorrect.  It would be safest to
exclude all data from those periods from any analysis.  Site operations
switched the heaters off and turned the converter back on on August 21,
1995.

As reported in a recent DQR, the fluxes from the EBBR are incorrect
presently because of a malfunctioning T/RH probe; no spares are presently
available.

SGP/EBBR/E13 - Battery voltage drop
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
On Friday 2 November, 1995 the instrument heaters were switched on.  By
4 November, the solar panel was not able to maintain the battery voltage for
the cold night conditions that existed.  On Monday, 5 November the heaters
were turned off, but the poor condition of the battery did not allow it,
once partially drained, to recharge sufficiently for nighttime conditions.
On 8 November, at 2106 GMT, the battery was replaced (resulting in missing
data for 2030-2130 GMT).  Most of the data for the period above is incorrect,
especially data from the sensors that require at least 11 volts DC power.
The data that is incorrect is listed below.

SGP/EBBR/E13 - AEM Exchange Stopped in Snow and Freezing Rain
DataStreams:sgp30ebbrE13.a1
Description:
On the night of November 10-11, a north-south line from south central
Kansas through south central Oklahoma received snow and freezing rain and experienced
below freezing temperatures.  This caused the EBBR automatic exchange mechanism (AEM) to
stop exchanging temporarily.   

Note that temperatures, relative humidities, and vapor pressures are not affected; these
are correct as measured, but the height at which the measurements occurred must be
determined from the home signal value.

The E13 battery condition was such that the solar panel was not able to
keep the battery voltage up (greater than 11 V DC) under cloudy conditions.
The data for the periods above is incorrect; many sensors require at least
11 volts DC power.  On 15 December 1995 at 1900 GMT the EBBR lost it's

SGP/EBBR/E13 - 3-month check
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
During EBBR 3 month checks the Automatic Exchange Mechanism is disabled
(reflected by home signals near zero) so that the two aspirator units can be
placed at the same height.  The measurements during this period, at least,
do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h),
or latent heat flux (e), nor do the air temperature and relative humidity
measurements indicate gradients.  Checks performed before or after the AEM
is disabled also lead to some incorrect data.  The period of incorrect
data for the EBBR is listed above; data times affected do not include the
beginning time and do include the ending time (data files are denoted by
the end time).

SGP/EBBR/E13 - Annual Calibration changeout
DataStreams:sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
On May 24, 1996 the changeout for annual calibration occurred at E13,
Central Facility, OK.  Between 1800 and 2130 GMT no data was remotely collected.
Furthermore, 5 minute data inbetween 1800 and 2130 is incorrect, 15 minute data 
between 1800 and 2130 is incorrect, and 30 minute data for 2130 GMT is 
incorrect.  A large jump in soil moisture appears in the data after the 
installation was completed (the soil bags holding the probes had a greater 
than ambient soil moisture).  Soil measurements indicated greater than ambient 
soil moisture until a rain just after 0600 GMT on 1 June saturated the soil; 
after this period the probes reflected actual soil moisture conditions.  

The larger than normal soil moistures have some impact on the soil heat flux 
during this time of year, and thus soil heat flux from the soil flow plates 
and soil temperature probes, as well as average soil heat flux, computed 
sensible and latent heat fluxes; these quantities should be considered to 
be incorrect from 24 June at 2130 GMT until about 1200 GMT on June 1.

Because of communication problems, data is missing from the time of the 
EBBR installation until 29 May 1996 at about 1815 GMT.  This data may be 
recovered from the sneakernetted data set.

SGP/EBBR/E13 - EBBR Biannual Checks
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
During EBBR 3 month checks the Automatic Exchange Mechanism is disabled 
(reflected by home signals near zero) so that the two aspirator units
can be placed at the same height.  The measurements during these periods 
do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), 
or latent heat flux (e), nor do the air temperature and relative humidity 
measurements indicate correct gradients.  Checks performed before or after the 
AEM is disabled also lead to some incorrect data.  Incorrect 5, 15 minute and 
half hour data occurs for periods indicated.

SGP/EBBR/E13 - Net Radiation Incorrect - Water in Bottom Dome
DataStreams:sgp15ebbrE13.a1, sgp30ebbrE13.a1, sgp5ebbrE13.a0
Description:
Water entered the net radiometer top dome through a hole made, probably,
by migrating birds (this happens every Spring and Autumn) and accumulated
in the bottom dome.  This causes nighttime net radiations to be too large
and daytime net radiations to be too small.  The data is therefore incorrect.
