SGP/EBBR - EBBR E20 Data Incorrect from SHF #5
DataStreams:sgp30ebbrE20.b1, sgp15ebbrE20.b1
Description:
something, since the problem began during J-panel changeout the 4/7/99 PM.
At the 7/21/99 PM, the reference temperature was repaired and reseated.  At
that time the SHF #5 data became correct again; the two events are probably
related only in that other connections, including that of the SHF #5, were
probably reseated at the same time.  The report of the PM activity is not
detailed enough to determine the exact causes and fixes.

The incorrect SHF #5 data can be identified by it being an order of 
magnitude larger than the values from the other soil heat flow sensors.

Affected data are:

5 minute:  none
15 minute: mv_hft5
30 minute: shf5, c_shf5, g5, ave_shf, e, h

SGP/EBBR - EBBR E18 Right Humidity Incorrect
DataStreams:sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:
After the 3 December 99 lightning strike, the humidity portion of the 
right T/RH probe drifted downwards at times, causing vapor pressure 
gradients to be incorrectly measured.  Therefore, sensible and latent
heat fluxes were also incorrect.  Since much of the data from the period
is missing (because of latent effects of the lightning strike), little
data is actually affected. 

The affected data values were:

5 minute:  hum_top, hum_bot, vp_top, vp_bot
15 minute: mv_hum_r
30 minute: hum_top, hum_bot, vp_top, vp_bot, bowen, h, e

SGP/EBBR/E20 - T/RH Check
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.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:  1520, 1525, 1530, 1535, 1540, 1545, 1550, 1555, 1600,
           1605
15 minute: 1530, 1545, 1600, 1615
30 minute: 1530, 1600, 1630

(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/E20 - 3-month Check
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.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.

a poor wire connection or a J-panel over-voltage protection device has failed.

Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can 
be recalculated using the remaining good sets of soil sensors as follows:
   ave_shf = (g1 + g3 + g4 + g5)/4
   e = -(q + ave_shf)/(1 + bowen)
   h = -(q + e + ave_shf)

SGP/EBBR/E20 - Reprocess: Soil Heat Flow #2 and #4 incorrect

SGP/EBBR/E20 - Pressure Sensor Data Incorrect
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
The E20 pressure sensor suffered
from spikes in pressure, which were related to 
increases in voltage during the day as the 
solar panels charged the battery.  These spikes
were not of a magnitude that would affect the 
30 minute surface fluxes.

Replacement of the pressure sensor solved the problem.

SGP/EBBR/E20 - Wrong Datalogger Program Installed
DataStreams:sgp30ebbrE20.b1
Description:
ts4 went offscale and sm4 dropped to a constant 16% when a "new" program
was installed on 3/30/05.  The wrong program was installed.

Because ts4 did not change with time, it did not mess up the calculation
of e and h.  e and h are slightly overestimated, but only by about 1%,
far less than the system error. This is a rare type of instrument problem where the 
concequences are minimal.

Therefore, e and h are not listed as incorrect in this DQR and are still usable during the 
stated period.

SGP/EBBR/E18 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE18.b1
Description:
Effective 20050330.0000, the EBBR.E18 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 20050330, 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 sgp30ebbrE18.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE18.a1).
Measurements:sgp30ebbrE18.b1:
  • 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/E20 - Net Radiation, Fluxes Too Large
DataStreams:sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
Net Radiation was way too large because of water in the bottom dome.
This resulted in the sensible and latent heat fluxes being too large also.

SGP/EBBR/E18 - Wind Direction Dependency of Surface Fluxes and General Data Quality 
Information
DataStreams:sgp30ebbrE18.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):

138-325

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/E18 - SHF #4 Measurements Too Low; Sensible and Latent Heat Fluxes Suspect
DataStreams:sgp15ebbrE18.b1, sgp30ebbrE18.b1
Description:
Soil heat flow #4 was replaced at the beginning of this period.  However, the soil heat 
flow measurements from that sensor were sometimes still lower than the lower limit imposed 
in the EBBR programming; sensible and latent heat flux were therefore deemed to be 
suspect during those times.  The cause of the low values could not be determined, but the 
values are not reasonable for the vegetation type at EF18.  

To remedy the situation, the soil heat flow sensor calibration was changed so that the 
sensor provided measurements that resembled the other four soil heat flow sensor 
measurements.

Soil heat flow measurements have been reasonable since the calibration change.

EBBR - soil heat flux plate giving opposite sign
DataStreams:sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
EDITOR'S NOTE: This DQR refers to data collected by the EBBR at E20 prior
to the begin date of regular ARM data.  At that time, the data streams which
contain the EBBR.E20 data were named
      Dsgp15ebbr6.a0
      Dsgp30ebbr6.a1
      Dsgp5ebbr6.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 930405.0000-930429.2359.


Soil heat flux sensor #3 of EBBR6, at Meeker, Ok extended site was
determined by me to have one heat flux plate whose output was out of phase
with the other four.  The absolute value of the soil heat flux value
produced by the plate was good.  Normally, this condition is caused either
by improper wiring of the sensor into the data acquisition system (this was
checked by site operations personnel on 29 April; wiring convention was
correct) or by the plate being installed upside down.  The latter seems
fairly obvious, although the plate was not dug up to check it's orientation;
that is not neccesary and would be detrimental since it takes time for such
sensors to acclimate themselves to their soil environment.

The consequence of this problem is that 5 soil heat flux plate outputs were
being averaged, with one of the outputs being of opposite sign from the
other four.  Since the outputs are similar, in absolute terms, this
essentially resulted in an average soil heat flux plate value that is 40%
too low.  In terms of output, this a reduction of around 10 W per meters
squared, or 1-2% of the RN+G term during maximum solar insolation.  This is
clearly a small error.

Site operations personnel switched the soil heat flux plate leads to give
the proper sign of output, on 29 April 1993, time unknown (this can be
determined from looking at the ingested data later; it hasn't been ingested
yet).  The instrument operated properly at that point.  Thus, the problem
has been corrected.

SGP/EBBR/E20 - Blown fuse in AEM at E20
DataStreams:sgp30ebbrE20.b1, sgp5ebbrE20.b1, sgp15ebbrE20.b1
Description:
On October 30, 1993, before 1300 GMT, the fuse in the AEM (Automatic
Exchange Mechanism) of Meeker, Ok (E20) EBBR blew out.  The AEM remained
nonfunctional until the fuse was replaced just before 1600 GMT on
November 12, 1993.  This situation resulted in the following invalid data:

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

15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, mv_home, 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, home_15, home_30


If the biases of the sensors were know, bowen, h, and e could be
recalculated from the 15 minute and/or 5 minute data.  Since we will not
have any idea of what those biases are until an annual calibration of the
sensors can take place (which may be months away), the recalculations
cannot be performed at this time.  Furthermore, it may be invalid to use
sensor biases, if determined too far removed in time, due to the gradual
calibration drift of some of the sensors.

SGP/EBBR/E20 - Reprocess: Questionable data in soil heat fluxes at E20
DataStreams:sgp30ebbrE20.b1, sgp15ebbrE20.b1
Description:
Soil heat flux probes #4 had been indicating soil heat fluxes that were
higher than the other four probes.  It was decided to replace it.
On November 24, 1993 Soil Heat Flux probe #4 was replaced, resulting in
outputs more similar to the other four probes.  This PIF does not
invalidate previous measurements by the old probe #4, but only indicates
data that is bad as a result of the replacement procedure.  This procedure
resulted in some bad data for the adjoining soil heat flux probes #3 and #5
also.  Bad data for #3 includes the 1600 GMT half hour, and 5 and 15 minute
periods between 1530 and 1600 GMT.  Bad data for #4 includes half hour
times of 1600 through 1900 GMT, with 5 and 15 minute data inbetween those times
being invalid as well.  Bad data for #5 includes half hour times of 1630
and 1700 GMT, with 5 and 15 minute periods inbetween those times being
invalid as well.  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 remaining functioning
set(s) of soil sensors.

Use the following equations:

ave_shf = (gs summed)/n,

    where n is the number of probes functioning

e = -(q + ave_shf)/(1 + bowen)   where q is net radiation, and bowen is
                                 Bowen Ratio
h = e * bowen

SGP/EBBR/E20 - Fan Stopped, T and RH Biases
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
Another fan stoppage situation occurred.  This is the fourth one in the
last few months and may indicate a weakening of the fans that aspirate the
temperature, relative humidity housings.  The 15 minute data reveals that
the stoppage occurred at approximately 1300 GMT on September 12.  The left fan
was cleaned out by site operations personnel and began running again at
1847 GMT on September 14.  The 15 minute data during this period shows that
during daytime, the left temperature was greater than the right temperature and
that the left relative humidity was lower than the right relative humidity
(a consequence of greater temperature), irregardless of the positions of the
housings.  The bowen ratio, sensible heat flux and latent heat flux for this
period, as well as all left housing temperatures and relative humidities are
incorrect.  The data values that are incorrect are:

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

15 minute: rr_thum_l, mv_hum_l, tair_l,

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

Because of the increased frequency of fan stoppage occurrences, I have
submitted a work request to site operations to use the portable vane
anemometer to check the flow of the housing fans on each EBBR and visually
check (and clean if needed) the fans for debris that would restrict the
flow.  Included in this work request are instructions for checking the
performance of the temperature and relative humidity sensors by
manually putting the aspirator housings at the same height for a half hour
period (so that two 15 minute and one half hour comparison result).

The latter part of the work request is prompted by my close inspection of
the Meeker data for the last few weeks.  It is clear that significant
biases have developed in the pairs of temperature and relative humidity
sensors; left thermocouple ~0.5 deg. C greater than right thermocouple,
left relative humidity ~5% lower than right relative humidity.  Biases were
expected in operating the systems over long time periods, and these appear
to be the result of simple offsets, not changes in calibrations.
At this point, I just want to determine how large the offsets are.

SGP/EBBR/E20 - Net Radiometer Hemisphere Changes
DataStreams:sgp30ebbrE20.b1, sgp15ebbrE20.b1, sgp5ebbrE20.b1
Description:
The upper hemisphere of the net radiometer at the site was punctured
allowing water to collect in the lower (and sometimes upper) section of the sensor. The 
punctures are most likely the result of migratory birds (a problem that we have experienced 
almost every year here at ANL also). The punctures (and water in some net radiometers) 
did not result in obvious invalidation of the data.

Whether there is water in the lower hemisphere or not, a small puncture of the upper 
hemisphere would not have a major effect on the net radiation measurement.  Significant 
amounts of water in the lower
hemisphere should have a major effect on nighttime measurements particularly, although 
that effect is hard to detect in the data. 
The date when the puncture occurred is approximate - but is certainly 
no more than two weeks before the hemisphere was replaced.

SGP/EBBR/E20 - AEM Home 30 Values Low
DataStreams:sgp5ebbrE20.b1, sgp30ebbrE20.b1
Description:
The first EBBR to achieve annual calibration changeout was Meeker, Ok, E20.
However, soon after changeout on August 9, 1995, the home 30 value dropped below
15, intermittently, to typically 0.3 to 0.5; this causes a data quality message
to be output in the site operations log as the stated acceptable range for home
30 is 15 to 34.999999.  However, no data is incorrect as a result of this
condition.

No replacement AEM is available, as the changeout kit AEMs are somewhat
different from the initial units.  Site operations hopes to have time to
diagnose the problem on the next PM visit and correct the problem.  At
present, data quality is not jeopardized.

I will submit another DQR or addendum when successful replacement of the
AEM is accomplished.

SGP/EBBR/E20 - Soil Heat Flow Zero Under Unchanging Conditions
DataStreams:sgp30ebbrE20.b1
Description:
This DQR is written to inform users of the data that the EBBR soil heat flow
measurements of zero during much of 11 November 1995 at E20, Meeker, OK are
correct values.  Nearly unchanging conditions of net radiation, air
temperature, and soil moisture, plus high wind speeds and near neutral
atmospheric stability, resulted in almost unchanging conditions of
soil temperature and ten and a half hours of zero soil heat flow
output from all soil heat flow plates (some plates outputted zero for
longer than this).  The change in energy storage (determined from the
change in temperature with time of the soil above the plates) was very
nearly zero also during the period of interest.

Such an extended period of zero soil heat flow and the accompanying
unchanging soil and atmospheric conditions is quite rare and therefore
worth noting here in case someone using the data might mistakenly think
that the data is incorrect.

SGP/EBBR/E20 - AEM Exchange Stopped in Snow and Freezing Rain
DataStreams:sgp30ebbrE20.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.

DataStreams:sgp30ebbrE20.b1, sgp5ebbrE20.b1, sgp15ebbrE20.b1, sgp5ebbrE20.00
Description:
Beginning on approximately October 1, 1996 the calibration of the temperature 
sensor in one or both T/RH probes began to drift; temperatures started to 
drift higher than the thermocouple probes.  This drift caused the upper and 
lower temperatures measured by the T/RH probe to be 2 to 10 degrees C greater 
than the thermocouple probes.  Comparison with adjacent EBBR sites shows 
that the thermocouples were measuring properly.  The problem affected the vapor 
pressure outputs primarily, making them as much as 1 kPa greater than they 
should be (vapor pressure is calculated from probe temperature and relative 
humidity).  The effect on sensible and latent heat fluxes was negligible, 
although latent heat flux may be overestimated by about 5% presently and 
sensible heat flux underestimated by approximately the same percentage.


Site operations replaced the T/RH probes on 8 May 1996; the new probes are 
performing well. The serial numbers of replaced probes are: Left 632415, 
Right 632356.  New probe serial numbers are: Left 460428, Right 460412.

SGP/EBBR/E20 - Wind Speed Cups Frozen
DataStreams:sgp30ebbrE20.b1, sgp5ebbrE20.b1, sgp15ebbrE20.b1
Description:
Freezing rain, snow, and below freezing conditions during 24 November 
1996 caused the wind speed sensor cups to freeze in a stopped state at E20, 
Meeker, OK.  On 25 November, the cups broke free of the ice and turned freely 
again. 

Measurements affected by the stalled wind speed sensor include:

5 minute:  wind_s, res_ws

15 minute: wind_s

30 minute: wind_s, res_ws
Measurements:sgp5ebbrE20.b1:

SGP/EBBR/E20 - Reprocess: E20 Soil Probes #3 Cables Cut
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1
Description:
The cables going to #3 soil temperature, moisture, and heat flow probes 
were cut by a mower on 11 June 1997 and were repaired on 16 July 1997.  
Data for the temperature probe was offscale, for the soil moisture probe 
was a constant 10.1 (close to the actual), and for the soil heat flow 
was large negative during the period. 

The following are the data quantities that were affected:

15 minute: rr_ts3, mv_hft3, r_sm3

30 minute: ts3, ces3, shf3, c_shf3, cs3, g3, ave_shf, e, h

Sensible, latent, and soil heat fluxes can be recalculated using the 
values from probes 1, 2, 4, and 5, as follows.

ave_shf = (g1 + g2 + g4 + g5)/4

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

h = -(e + ave_shf +q)

SGP/EBBR/E18 - Reprocess: E18 EBBR Net Radiometer Calibration
DataStreams:sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:
When the CR10 program was loaded in the storage module of the newly 
installed EBBR unit at E18 on 10 September 1997, an incorrect 
calibration for the net radiometer was present.  The incorrect calibration
had apparently been entered into the storage module by the vendor before
the unit was shipped.  The .DOC file showed the correct calibration; 
therefore, we did not suspect a problem until comparisons with 
radiometers at other sites nearby were performed.  The program with the 
correct calibration was entered on 18 June 1998.  The 15 minute mv_q 
values were not affected.  The 5 and 30 minute q values during the period
above need to be corrected; multiply positive q values by 0.684, multiply 
negative values by 0.811; Sensible (h) and Latent Heat (e) fluxes for the
period need to be recalculated with the equations below.

SGP/EBBR/E20 - Pressure Low
DataStreams:sgp5ebbrE20.b1, sgp15ebbrE20.b1, sgp30ebbrE20.b1
Description:
The pressure sensor values dropped several kPa on 13 January 1999 because 
of a sensor malfunction and remained that way until the sensor was 
replaced on 10 February 1999.  Comparison of the pressure before and after
the problem period shows that Bowen ratio was underestimated by 
approximately 6% during the period, resulting in a 6% overestimation of
latent heat flux and a 6% underestimation of sensible heat flux.  
Adjustment of the flux data during the period by these amounts should be
made by the data user.

SGP/EBBR/E18 - Pressure Incorrect
DataStreams:sgp30ebbrE18.b1, sgp5ebbrE18.b1, sgp5ebbrE18.00
Description:
The pressure sensor was replaced at E18 EBBR without the replacement being
noted by Site Ops and therefore without an indication of serial number and
thus correct calibration. The serial number of the sensor was observed 
during a PM (after months of confusion concerning the thing) and a several
month search for the calibration sheet at ANL, the CF, and the manufacturer
ensued.  The sheet was finally found and I confirmed that an incorrect
offset was being used (the same as used for the previous sensor). This is
an easy error to make as there are two models of pressure sensors (with
different calibration ranges) being used in the EBBR systems.  On June
17, 1999 the correct offset was entered into the CR10 and storage module
programming.  The pressure for the period should be increased by 6.757 kPa.
The result of the error is that Bowen ratio was underestimated by 6.8% on
average, Latent Heat Flux was overestimated by 3.6% on average, and Sensible
Heat Flux was underestimated by 3.6% on average.  The errors in the fluxes 
are smaller than the estimated 10% error in the Bowen ratio flux 
measurement technique and therefore the data does not need to be reprocessed.
Anyone performing area averages of pressure or looking at the variation in 
pressure over the CART Site should adjust the E18 EBBR pressure values for this
period using the offset error indicated above.
