SGP/EBBR/E13 - Reprocess: E13 EBBR Soil heat Flows #1 and #2 Incorrect

Soil Heat Flow probes #1 and #2 were incorrect during the
indicated period (and for some time afterward, to be covered in another
DQR).  Outputs from the probes were typically too large negative or 
too large positive.

SGP EBBR E13 - E13 EBBR Left T/RH Probe Temperature Incorrect

The left T/RH Probe Temperature was often incorrect, causing the other indicated
measurements to be incorrect also.  

When the home30 signal had an offset, the top RH probe temperature was incorrect
but not the bottom RH probe temperature.

SGP EBBR E13 - E13 EBBR AEM Home 30 Offset

The AEM home30 signal is offset by approximately 25;
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 this condition.

be recalculated using the remaining good sets of soil sensors as follows:

SGP/EBBR/E13 - AEM Hung up

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.

Soil heat flow 3 was incorrect, with values too large positive and too small negative.  
Since the calibration in the program is the one supplied by the vendor, it appears 
that the calibration may be wrong.

Average soil heat flow, sensible heat flux and latent heat flux can be recalculated
using the remaining good sets of soil sensors as follows:

SGP/EBBR/E19 - Pressure Incorrect

The pressure measurement was incorrect.  This is used to determine the Bowen ratio, 
thereby affecting the sensible and latent heat fluxes also.

SGP/EBBR/E19 - Measurements Incorrect After CR10 Replacement

Replacement of the CR10 datalogger caused most measurements to be incorrect, reason 
unknown.
A different logger was installed at the end of the specified period and this resolved the 
problem.

SGP/EBBR/E13 - Reprocess: Soil Heat Flow #1 and #2 Incorrect

Soil Heat Flow #1 and #2 were incorrect during the indicated period.

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 = (g3 + g4 + g5)/3
   e = -(q + ave_shf)/(1 + bowen)
   h = -(q + e + ave_shf)

SGP/EBBR/E18 - Data Incorrect After Logger Restart

Because soil temperature measurements were not available 
from the beginning of the half hour, the change in soil 
energy storage could not be calculated and thus is 
incorrect.

There is no fix to this problem. Average Soil Heat Flow, 
Sensible Heat Flux (h), and Latent Heat Flux (e) can not 
be calculated using the available, remaining measurements.

SGP/EBBR/E13 - Wind Speed Stalling at Low Speeds

Perhaps because of excessive bearing wear, the wind speed sensor
had a high starting threshhold with wind speeds below about 2 m/s.
Wind speed measurements at all speeds were probably too low.

• Wind speed, lower, 1-min avg(wspd_arith_mean)

#2 continues to be flaky, suggesting that the sensor
itself has a problem.  A DQPR has been submitted to
replace #2.  The indicated measurements 
that are calculated using soil temperature are 
also suspect.  However, the intermittent problems normally

SGP/EBBR/E15 - Wind Direction 10 Degrees Low

The wind direction at E15 EBBR was 10 degrees low for the period (since
installation of the EBBR unit on 10/11/01). The wind direction sensor was apparently 
aligned to magnetic north instead of true north at installation.

SGP/EBBR/E15 - Top Humidity reported as zero in 30 minute data.

The top relative humidity was reported as zero in the 30 minute data.
This is an apparent misreporting by the CR10 datalogger or is caused by
a communications problem in accessing the data from the datalogger.  It is very 
infrequently seen; it's actual cause is unknown. No other data was
affected.

SGP/EBBR/E19  - Water in Net Radiometer; Surface Fluxes are Incorrect

The net radiometer top dome was punctured by migrating birds.  This alone does not cause 
incorrect net radiation measurements.  However, when it subsequently rains, water collects 
in the bottom dome, causing the net radiation measurements to be too large during the 
day and too small at night.

SGP/EBBR/E19 - Battery Voltage Too Low, Most Measurements Incorrect

Battery voltage dropped below levels required to sustain the 
               production of valid data.  The AC charger unit had failed.  
               This prevented charging of the battery during the night and
               prevented the solar panel regulator from properly charging 
               the battery during the day.
