SGP/EBBR - EBBR E4 Soil Heat Flux Values Too Large
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1
Description:
Soil Heat flux from probes #1 and #4 are incorrect for the period.  The
flux values output were larger than what could be considered reasonable, 
for unknown reasons.

SGP/EBBR/E4 - T/RH Check
DataStreams:sgp5ebbrE4.b1, sgp15ebbrE4.b1, sgp30ebbrE4.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

           vp_top, vp_bot, bowen, e, h

           1705, 1710, 1715, 1720, 1725, 1730, 1735, 1740
15 minute: 1630, 1645, 1700, 1715, 1730, 1745
30 minute: 1630, 1700, 1730, 1800

(EDITORS 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/E4 - 3-month Check
DataStreams:sgp5ebbrE4.b1, sgp15ebbrE4.b1, sgp30ebbrE4.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.

SGP/EBBR/E4 - Reprocess: Bad soil heat flux sensor #4
DataStreams:sgp30ebbrE4.b1, sgp15ebbrE4.b1
Description:
On September 11, 1993 soil heat flux sensor #4 of the Plevna, KS EBBR
(E4) malfunctioned.  The sensor was replaced September 23, 1993 before
1600. Corrupted 30 minute values of shf4, c_shf4, g4, ave_shf, h, and e,
and corrupted 15 minute values of mv_hft4 resulted from the sensor
malfunction.  

The quantities shf4, c_shf4, g4, and mv_hft4 are bad data values and are not 
recoverable.  The other quantities can be recalculated using the three
functioning sets of soil sensors. (Note: Soil heat flux sensor #5 was also
malfunctioning during the time periods identified and has therefore been
eliminated from the recalculation equations.  This problem is identified
in a separate DQR.)

SGP/EBBR/E4 - Reprocess: Bad soil heat flux sensor #5
DataStreams:sgp30ebbrE4.b1, sgp15ebbrE4.b1
Description:
On September 1, 1993 the EBBR system at Plevna, E4, was relocated in the
same field.  However, soil contact for soil heat flux plate #5 was not
properly established.  This resulted in somewhat high positive and very
high negative outputs, depending on the direction of soil heat flow.
Corrupted 30 minute values of shf4, c_shf4, g4, ave_shf, h, and e,
and corrupted 15 minute values of mv_hft4 resulted.

The quantities shf4, c_shf4, g4, and mv_hft4 are bad data values and
are not recoverable.  The other quantities can be recalculated using
the four functioning sets of soil sensors. (Note: Soil heat flux 
sensor #4 was also malfunctioning during part of the time period 
identified.  That problem is identified in two separate DQRs.  See
D931108.5 and D020701.2 for the equations to use while sensor #4
was not working properly)

Sensible, latent, and soil heat fluxes can be recalculated using the
change in energy storage of probes 1-4 as follows.

ave_shf = (g1 + g2 + g3 + g4)/4
e = -(q + ave_shf)/(1 + bowen)
h = -(e + ave_shf +q)

SGP/EBBR/E4 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE4.b1
Description:
Effective 20050323.1800, the EBBR.E4 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 20050323, 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 sgp30ebbrE4.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE4.a1).
Measurements:sgp30ebbrE4.b1:
  • Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)
  • Average soil heat flow at the surface(surface_soil_heat_flux_avg)
  • Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux)

SGP/EBBR/E4 - Wind Direction Dependency of Surface Fluxes and General Data Quality 
Information
DataStreams:sgp30ebbrE4.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):

0-158, 202-360

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/E4 - Reprocess: Intermittently bad soil heat flux sensor #4
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1
Description:
On October 23, 1993 soil heat flux sensor #4 (which had been installed on
September 23, 1993) of the Plevna, KS EBBR (E4) developed an intermittent poor
electrical contact with the multiplexer.  Corrupted 30 minute values of shf4,
c_shf4, g4, ave_shf, h, and e, and corrupted 15 minute values of mv_hft4
resulted from this situation.  

The quantities shf4, c_shf4, g4, and mv_hft4 are bad data values and are not 
recoverable.  The other quantities can be recalculated using the three
functioning sets of soil sensors. (Note: Soil heat flux sensor #5 was also
malfunctioning during the time periods identified and has therefore been
eliminated from the recalculation equations.  This problem is identified
in a separate DQR.)

ave_shf = (g1 + g2 + g3)/3
e = -(q + ave_shf)/(1 + bowen)
h = -(e + ave_shf + q)

SGP/EBBR/E4 - AEM malfunction
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:
Beginning when the E4, Plevna EBBR was moved to a different location in the
same area on August 29, 1993, the home_15 signal began to malfunction
intermittently.  The home_15 signal is normally between 45 and 53; in the
case where it malfunctions, it reads approximately 22.  The home signal is
sampled only once per fifteen minute period to indicate the position of the
Automatic Exchange Mechanism (AEM).  However, the realtime value is used every
30 seconds to determine the sign of the gradient of temperature and relative
humidity.  Clearly, the 15 minute sample may not always reflect the proper
position if something is wrong with the AEM.  Therefore, when the home_15
signal is incorrect for a half hour, it is wise to view the preceding and
successive half hours of data with suspicion as well as the half hour of
interest.  Affected data are 5 minute values of mv_home; 15 values of
tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot, vp_top, vp_bot,
and home; 30 minute values of tair_top, tair_bot, thum_top, thum_bot,
hum_top, hum_bot, vp_top, vp_bot, bowen, e, h, and home_15.  The dates on
which this problem occurred were (all 1993) August 29, September 2, 3, 6-8,
10-16, 18-29, October 1-11, 13-31, and November 1-4.

On November 4, 1993 the AEM was replaced at Plevna, correcting the problem
described in this PIF.

On February 22, 1994 the EBBR wind speed sensor at E4, Plevna, KS was
frozen to a stationary condition by ice.  It broke free in a strong wind on
February 23, 1994.  Invalid data for the time period indicated is:

SGP/EBBR/E4 - Improper Net Radiometer Calibration
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:
When a replacement net radiometer was installed on March 10, 1994, the
calibration sheet for the new sensor could not be found.  That was because
the manufacturer had not provided one with the instrument.  So, the
calibration for the previous sensor was left in the EBBR CR10 program.
I obtained the calibration sheet from the manufacturer, and upon return to
Plevna on the next preventative maintenance visit, on March 24, site
operations personnel entered the correct calibration into the program.  The
change in calibration was from 13.1 to 13.0.  This change has negligible (
less than one percent) effects on calculations in the program and does not
warrant recalculations.  However, the net radiation itself could be
recalculated by multiplying by the ratio of 13.0 to 13.1.

SGP/EBBR/E4 - Soil Heat Flux Plate #5
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:
Soil heat flux plate #5 has indicated high at extremes, for both positive and
negative outputs.  At around -130 watts per meter squared for #5, the other
four heat flux plates indicated approximately half as much.  After
replacement on June 2, 1994 at 1752 GMT, SHF #5 is now very similar to the
other four plates.  The effect on average soil heat flux amounted to only
about 2% of the net radiation value at the worst; this is within the
accuracy of the net radiation measurement and therefore does not require
recalculation of the sensible and latent heat fluxes.

SGP/EBBR/E4 - Pressure
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:
Damage to some pressure sensors as a result, apparently, of high battery
voltage, caused pressure readings to vary significantly at a few EBBRs for
several months.  I am being intentionally vague in making that statement as
there are DQRs and at least one PIF that cover those cases, except for the
situation at E4, Plevna, KS.  Some time ago I had the suspect pressure sensors
replaced and "repaired".  Unfortunately, the repairs were insufficient, as
we found out by using Plevna as a guinea pig for the "repaired" sensors to
see if they were working.  It turns out that the three repaired sensors S/N
6500, 6504, and 6509 were better, but still experienced fluctuations in
output that followed battery voltage level as the battery was charged by
the solar panel during the daylight hours.  The fluctuations look like
long-term spikes, positive or negative at different times, and lasted from one
to several hours.  The fluctuations had minimal impact on adjustments to
computed values from the EBBR.

Pressure data from Plevna for the period listed above should not be used
for absolute values.  That is why I marked "questionable", in the data
labelling section, but this applies only to the pressure data itself.

The following documents the use of pressure sensors at Plevna:

1)  The original sensor, S/N 6509 was removed for repair on 1/13/94 and
    replaced with the "repaired" S/N 6500.

2)  S/N 6500 was removed for repair on 2/10/94 and replaced with the
    "repaired" S/N 6504.

3)  S/N 6504 was removed on 3/24/94 and replaced with "repaired" (2nd
    time) S/N 6500.

4)  S/N 6500 was removed on 5/5/94 and replaced with "repaired" (2nd time) S/N
    6504.

5)  S/N 6504 was removed on 5/19/94 and replaced with "repaired" S/N
    6509.

6)  S/N 6509 was removed on 6/30/94 and replaced with a new sensor, S/N
    6579.

Sensors 6500, 6504, and 6509 have been thrown away, as the manufacturer
appears to be incapable of repairing them completely.  Rather than waste
more money in trying to have them repaired, I ordered three new pressure
sensors, of which S/N 6579 is one.  Thus, we now have two new sensors as spares.

Description:
During two periods recently, the wind direction sensor at E4, Plevna, KS
malfunctioned.  The first time period was caused by water in the connector
to the sensor.  The second period was apparently a result of an electronics
problem in the sensor circuitry.  On June 30, at 1646 GMT sensor S/N 3036
was removed and replaced with S/N 3034.  On July 11, at 2003 GMT, sensor
S/N 3034 was replaced with S/N 3038.  The periods of time listed above are
inclusive for the 30 minute data.  Slightly less of the 5 and 15 minute
values were affected (at the beginning or end of the periods), as is obvious
from the sensor replacement times.  All of the data should be considered
incorrect.  The affected data are:

SGP/EBBR/E4 - Annual calibration changeout
DataStreams:sgp30ebbrE4.b1, sgp15ebbrE4.b1
Description:
On October 25, 1995 the changeout for annual calibration occurred at E4,
Plevna, KS.  SEBS unit 8 was removed and unit 12 was installed.  Between
1630 and 2130 GMT no data was collected.  The soil moisture sensors were
shipped dry from the vendor.  Site operations did not realize this and
installed them without wetting the bags that hold the soil moisture sensors
in soil.  Site operations did soak the soil after installing the sensors (
as per the procedure).  The water did not penetrate into the bags of soil.
Therefore, all soil moisture sensor outputs remained offscale until
October 26.  At that point only SM1 came onscale.

This situation continued until 1 November 1995.  A couple of days before that
the mentor discovered (in a conversation with the vendor) that the wrong SEBS
unit had been installed.  Unit 13 was the unit for which soil specific soil
moisture sensor calibrations had been performed for Plevna; this had not been
made clear either to the mentor or to site operations.  On 1 November SEBS
unit 12 was removed from Plevna and SEBS 13 was installed.  No data was
collected between 1630 and 2100 GMT.

For SEBS unit 13, SM1, SM3, and SM5 were offscale initially.  SM5 came
onscale on 3 November, although the data from it was incorrect until 1900
GMT on 4 November.  SM1 and SM3 came onscale on 7 November, went offscale
for a short period on 8 November and stabilized to correct levels at the
beginning of 10 November.  All data since then is correct.

Most of the data from the use of SEBS 12 at Plevna is incorrect.  It would
be wise to not use it.  The incorrect soil moisture after SEBS 13 was
installed affected numerous other data values including:

SGP/EBBR/E4 - Soil Moisture Probes Offscale
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1
Description:
During numerous periods within the days listed above, individual soil
moisture probes indicated high or offscale, on the dry side.  The
calibration of the probes in Plevna soil by REBS was inadequate to
provide reliable soil moisture data. 

The data should be carefully inspected before use: soil moistures
less than 3 should be considered incorrect; recalculation of ave_shf 
e, and h may be made using only the soil moisture sets with valid
soil moisture values.

Affected data values are (# represents probe number):

15 minute: rr_sm#
30 minute: sm#, c_shf#, cs#, ces#, g#, ave_shf, e, h

Sensible, latent, and soil heat fluxes can be recalculated using the soil
probe sets that provide correct data.  For example, if soil moisture 1 is
incorrect:

ave_shf = (g2 + g3 + g4 + g5)/4
e = -(q + ave_shf)/(1 +bowen)
h = -(e + ave_shf +q)

SGP/EBBR/E4 - Reprocess: Soil Moisture Probe Low at Times
DataStreams:sgp30ebbrE4.b1, sgp15ebbrE4.b1
Description:
On 18 June 1996, soil moisture probe 5 data reduced to a very low level.  
At 0000 GMT on 19 June 1996 the soil moisture indicated below zero, which 
is not physically possible.  Over the next few months the soil dried to a 
low enough moisture level that the output again went too low.  The qc 
minimum limit of 0 will indicate these times.  The output recovered to 
reasonable values on 1 July at 2100 GMT.  It again went low on 4 
July at 0100 and remained that way until at least 8 July.  No data is 
available from 9 July to 24 July to allow us to see the behavior during 
that period.  On 27 July, at 0330 GMT, the output was very high (113.8) for 
some unknown reason.  The output also went offscale at 0000 on 3 August, 
for an unknown reason.  The output again went low at 0800-1530 GMT on 10 
September and 0000 GMT on 11 September through 0900 GMT on 15 September.  No 
incorrect values have occurred since.  However, it is clear that at very 
low soil moisture, probe 5 indicates lower than normal.  It will be replaced 
when a spare is available.

SGP/EBBR/E4 - Soil Moisture Sensor Offscale
DataStreams:sgp30ebbrE4.b1
Description:
The 30 minute output of soil moisture sensor #5 at Plevna, Ok, E4 has been 
going to a large magnitude negative number for low soil moistures for 
several months.  The calibration coefficients were inadequate for low soil 
moistures.  The coefficients have been changed to yield correct soil
moistures at low soil moisture (at least, manipulation of the polynomial 
for low soil moistures yields correct results for a fixed temperature 
correction - extremes of soil temperature and thus the correction may not 
yield as satisfying results).  These coefficients were derived from the
original calibration data, but including use of low values not used 
originally.  This particular probe's calibration data was almost exactly
the same as another probe used at the same site, yet the coefficients
derived by the vendor were very different.  This made it particularly
obvious that the original coefficients were not adequately tested 
(verification tests are not normally performed with dry soil, so this kind 
of problem would not normally show up during verification tests).  Several 
days of data using the new coefficients yields encouraging results.  I will 
continue to inspect the data to determine the success of this change.

SGP/EBBR/E4 - EBBR Net Radiometer Domes Pierced, Water Inside - Data Affected
DataStreams:sgp5ebbrE4.b1, sgp30ebbrE4.b1, sgp15ebbrE4.b1
Description:
The upper dome of the EBBR net radiometers was punctured.
After the puncture, water collected in the top and/or bottom dome.  The
water was removed and the dome was replaced during PM visits. 

 In some cases, the puncture and water resulted in incorrect data. 
Comparison with net radiation values from surrounding EBBR sites and the
SIRS is neccesary to determine if the EBBR net radiation data 
are correct or incorrect.

It is often difficult to tell from the data when the punctures occurred,
but they would have existed for no more than 2 weeks, since the domes
are checked during each two-weekly PM visit.

Incorrect net radiation data results in the latent heat flux and
sensible heat flux also being incorrect.

SGP/EBBR/E4 - EBBR E4 Low Battery - Resulting In Incorrect Data
DataStreams:sgp5ebbrE4.b1, sgp15ebbrE4.b1, sgp30ebbrE4.b1
Description:
A low battery condition (less than 10.5 volts) caused a number of data
fields to be incorrect at some times and all data fields to be incorrect
at a more limited number of times.  All data fields are suspect when the
battery voltage drops below 10.5 volts because the CR10 cannot operate 
properly.  Some sensors are affected slightly (i.e. pressure) at slightly
larger voltages.  The low battery condition resulted from an initially 
weak battery and a week of extremely low solar radiation (from heavy 
cloudiness) on the solar panel that provides most of the charging of the
battery. 

Comments added by Marv Wesely: 
David Cook has been working with Dave Breedlove to try to assess the age
of the batteries.  The dates on the batteries need to be read during 
site visits and provided to David C.  It's quite possible that they need
to be replaced.  It's work in progress, though slow at times.

SGP/EBBR/E4 - EBBR E4 Low Battery Voltage
DataStreams:sgp5ebbrE4.b1, sgp15ebbrE4.b1, sgp30ebbrE4.b1
Description:
On 29 April 1998 the battery voltage dropped to below 10.5 volts.  No data,
except for battery voltage, can be assumed to be correct during this period.
The battery was replaced at 1830 GMT.  The cause of the problem appears to
be a failed solar panel charger/regulator. The voltage of the new battery
has dropped steadily since installation; it is apparently not being charged.
A work request has been submitted to have the charger/regulator replaced.

SGP/EBBR/E4 - EBBR E4 6-Month Checks
DataStreams:sgp5ebbrE4.b1, sgp30ebbrE4.b1, sgp15ebbrE4.b1
Description:
During EBBR 6-month checks (formally called 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 just before or after the AEM is disabled also lead to some 
incorrect data.  Incorrect 5, 15 minute and half hour data occurs for the 
period above.

SGP/EBBR/E4 - Reprocess: E4 EBBR Soil Moisture #5 Offscale In Dry Conditions
DataStreams:sgp30ebbrE4.b1
Description:
The soil moisture dropped so low that soil moisture could not
be properly calculated by the polynomial equation that converts soil 
moisture sensor resistance into soil moisture percent.  This has happened
on occasion at other EBBR sites.  All 30 minute soil moisture #5 data for 
this period is incorrect (15 minute resistance values are okay); this 
affects the calculation of average soil heat flow through contamination
of the soil storage term and thus sensible and latent heat fluxes.  
The thirty minute values that are incorrect are:

  sm5, c_shf5, cs5, ces5, g5, ave_shf, e, h.

SGP/EBBR/E4 - EBBR E4 Data Missing
DataStreams:sgp5ebbrE4.b1, sgp15ebbrE4.b1, sgp30ebbrE4.b1
Description:
Most of the data for the period is missing.  The solar panel regulator was
not working, allowing the EBBR battery to slowly and steadily be depleted.
The voltage level dropped too low for the system to continue to operate and
data was lost or was not measured.  A new regulator was installed on 27 May
and data collection was resumed.

SGP/EBBR/E4 - E4 EBBR Battery Voltage Low
DataStreams:sgp5ebbrE4.b1, sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.00
Description:
A blown fuse in the AEM stopped it at a position other than a home position.
This created a condition where the battery drained more rapidly than normal,
causing the voltage to drop below the acceptable voltage of 10.4 V at times.
The 15 minute data shows battery voltage; all 5, 15, and 30 minute data for 
voltages less than 10.4 volts should be considered to be incorrect.
