SGP/EBBR/E13 - failure of sensors
DataStreams:sgp30ebbrE13.b1, sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp5ebbrE13.00
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:sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.00
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.

SGP EBBR E13 - E13 EBBR Soil T #4 Incorrect
DataStreams:sgp30ebbrE13.b1, sgp15ebbrE13.b1
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.

Description:
This condition occurred most of the time during the

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.

DataStreams:sgp30ebbrE13.b1, sgp15ebbrE13.b1, sgp5ebbrE13.b1
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.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
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
15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, tair_r, tair_l
30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
           vp_top, vp_bot, bowen, e, h

5 minute:  2005, 2010, 2015, 2020, 2025, 2030, 2035, 2040, 2045,
           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.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
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.

SGP/EBBR/E13 - AEM Hung up
DataStreams:sgp30ebbrE13.b1, sgp5ebbrE13.b1, sgp15ebbrE13.b1
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).

  • Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux)
  • Average soil heat flow at the surface(surface_soil_heat_flux_avg)

SGP/EBBR/E13 - Wind Direction Dependency of Surface Fluxes and General Data Quality 
Information
DataStreams:sgp30ebbrE13.b1
Description:
Beginning in FY2006, Data Quality Reports are not written for missing 
data or for situations when qc flags clearly show that the data is 
incorrect (this is true for most of the conditions listed below).  
DQRs are written for periods when data is incorrect, when the situation 
is not represented by qc flags in the data, and it's not obvious that 
the data should have been flagged as incorrect.

The EBBR data is only useful for particular wind directions at each 
Extended Facility.  Please use the following resources to help in 
interpreting the EBBR data.

1) qc flags in the EBBR data.

2) Instrument Mentor Monthly Summaries (IMMS) at http://www.db.arm.gov/IMMS/

3) SGP EF Surface Conditions Observations (EFSCO) at 
http://198.124.96.210:591/sfc_cond1/default.htm

4) Surface fluxes are valid only for the following wind directions
(in degrees):

0-52, 142-194, 328-360

Note that there are wind directions at most sites for which the fetch
is insufficient and therefore EBBR data is invalid.  Appropriate 
fetch was determined from a 1/40 measurement height to fetch ratio, 
resulting in a required minimum fetch of 120 m.  Particular attention 
should be paid to the limited valid wind directions for the Central 
Facility EBBR.  The surface vegetation type for the EBBRs is grazed 
or ungrazed grassland (refer to the EFSCO for state).

5) Some conditions that commonly cause the EBBR primary measurements to 
be incorrect or missing follow:

a) Sensible and latent heat fluxes are not accurate during times when 
the Automatic Exchange Mechanism (AEM) is not functioning properly.  
The AEM switches the gradient measuring instrumentation between the 
top and bottom positions every 15 minutes; this reduces the effects of 
instrument offsets.  Sometimes the AEM does not reach it's full extent 
of travel, resulting in the home signal being zero.  

b) Sensible and latent heat fluxes are sometimes incorrect when surface 
soil heat flow is out of range, as seen in the average soil heat flux 
(ave_shf).

c) Very light winds may be seen at nights for brief periods. Wind 
direction flops around a lot during low wind conditions (< 1.5 m/s) 
and is often unreliable during those periods.

d) Missing data periods occur at times; this is usually a site data 
system collection/communication problem; it can also occur during 
replacement of the system with a newly calibrated unit.  Missing data 
is sometimes filled in later from manual or automatic re-collection of 
the data.

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 - pressure calibration
DataStreams:sgp30ebbrE13.b1
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.b1
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.b1, sgp30ebbrE13.b1
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

15 minute  1515 and 1530 GMT

5 minute   1515, 1520, 1525, and 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.

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.

 Discussion of Problem:

On February 14, 1995 a frontal system deposited freezing rain in central
Oklahoma that resulted in the EBBR wind speed instrument becoming frozen in
place at the Central Facillity (E13) for part of a day.  All 5, 15, and 30
minute data values indicated below are incorrect for the period listed above.

5 minute:  wind_s, res_ws
15 minute: wind_s

SGP/EBBR/E13 - Reprocess: Soil Temperature Malfunction
DataStreams:sgp15ebbrE13.b1, sgp30ebbrE13.b1
Description:
For several days, soil temperature probe #4 indicated values
that were either too high or too low, for unknown reasons.  After Site
Operations personnel checked connections, it recovered to proper values.
Affected quantities are shown below.

15 minute: rr_ts4

30 minute: ts4, ces4, g4, ave_shf, e, h

Sensible, latent, and soil heat fluxes need to be recalculated using the
change in energy storage of probes 1-3 and 5, as follows.

ave_shf = (g1 + g2 + g3 + g5)/4

e = -(q + ave_shf)/(1 +bowen)

h = -(e + ave_shf +q)

SGP/EBBR/E13 - Low Battery Voltage and AEM Left on Manual
DataStreams:sgp30ebbrE13.b1, sgp5ebbrE13.b1
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
30 minute values are also incorrect at 1630 GMT.

SGP/EBBR/E13 - Battery Voltage Drop
DataStreams:sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
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.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
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.

DataStreams:sgp30ebbrE13.b1
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.

SGP/EBBR/E13 - 3-month check
DataStreams:sgp30ebbrE13.b1, sgp5ebbrE13.b1, sgp15ebbrE13.b1
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.b1, sgp5ebbrE13.b1
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.

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
