SGP/EBBR/E27 - Missing data during system update
DataStreams:sgp5ebbrE27.b1, sgp15ebbrE27.b1, sgp30ebbrE27.b1
Description:
Some soil parameters were slightly incorrect since EBBR.E27 was 
                 installed in May 2003.  While the coefficients were being updated,
                 data collection was suspended resulting in missing data for the 
                 specified period.
                    No significant effects (1% or less) on the surface heat flux data 
                 would have occurred from using the slightly incorrect coefficients. 
                 Therefore, flagging of the surface flux data from the time of 
                 installation of E27 is unwarranted.

SGP/EBBR/E26 - AEM Home Signals Incorrect, Surface Fluxes Incorrect
DataStreams:sgp5ebbrE26.b1, sgp15ebbrE26.b1, sgp30ebbrE26.b1
Description:
During a preventative maintenance visit to perform the 6-month
calibrations, the home15 and home30 outputs began reading the
same as one another.  A fuse replacement and lubrication of the 
AEM sprockets on 11/13 corrected the problem.

During the interval specified, the home15, home30, and sensible
and latent heat fluxes are incorrect.

               This prevented charging of the battery during the night and

SGP/EBBR/E12 - Pressure Sensor Measurement Scales With Battery Voltage
DataStreams:sgp5ebbrE12.b1, sgp15ebbrE12.b1, sgp30ebbrE12.b1
Description:
The barometer output was scaling with supply voltage (i.e. it 
               followed the charging of the battery by the solar panel).

               NOTE: The barometer was replaced later than the end date of 
               this DQR.  Why the problem ended on 26 Nov 2003 is unclear; 
               there was no site ops intervention on that date.

               The problem did not affect the sensible and latent heat flux 
               calculations beyond the expected system error.

SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect
DataStreams:sgp5ebbrE26.b1, sgp15ebbrE26.b1, sgp30ebbrE26.b1
Description:
In a trip to E26, I found that a bad spark gap through which the barometer was powered was 
causing pressure measurements to be incorrect.  The pressure readings oscillated with 
the voltage of the EBBR battery.  During daytime the voltage and thus the pressure would 
increase and vice versa during dark hours.

Apparently only the positive side of the power supply was properly connected through the 
spark gap and thus the voltage received by the pressure sensor was lower than required to 
power it properly.  Under this condition the perssure measurement varies with voltage 
level.  The pressure measurements therefore had a diurnal signature and usually were 
incorrect.  

The decreased pressure during most times would cause latent heat flux to be slightly 
overestimated and sensible heat flux to be slightly underestimated.

  • Atmospheric pressure(mv_pres)

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

Replacement of the pressure sensor solved the problem.

SGP/EBBR/E15 - Net Radiometer not level
DataStreams:sgp5ebbrE15.b1, sgp30ebbrE15.b1
Description:
The EBBR net radiometer at E15 was suspected to be off of level
               because the daily peak net radiation was recorded later than it 
               was recorded by the SIRS.

               Site Ops found the EBBR net radiometer at E15 was significantly 
               off of level (1/2 bubble tipped to the north).  Adjustment of 
               the level improved the comparison of peak time with the 
               co-located SIRS.

               There was no significant effect on the sensible and latent heat 
               fluxes.

SGP/EBBR/E19 - Reprocess: Incorrect Net Rad Calibration Coefficient
DataStreams:sgp5ebbrE19.b1, sgp30ebbrE19.b1, sgp30baebbrE19.c1
Description:
The net radiometer coefficient installed on 2/5/04 for nighttime (negative voltage 
calibration) was incorrect.

Negative net radiations during the subject period can be multiplied by
0.9419 to get corrected net radiation measurements.  The sensible (H)
and latent heat (LE) fluxes (which are very small at night anyway) can
be recalculated using the following equations (where B is Bowen ratio,
Rn is corrected net radiation, and G is soil heat flow):

LE = -(Rn + G)/(B + 1)

H = -(Rn + G + LE)

SGP/EBBR/E15 - Soil Moisture Coefficients Incorrect
DataStreams:sgp30ebbrE15.b1
Description:
The soil Moisture coefficients used for E15 were incorrect from the time of
installation of the system in program version 8.  On 9 July 02 parameter 4  (an offset 
value) of program step 136 was changed from 9.5264 to the correct value 0.95264 (this error 
had been made by the vendor). The error masked the real problem (wrong soil type) and 
after 9 July 02 resulted in very low soil moisture measurements.  The coefficients used were 
for coarse sand.  On 28 Sep 04 I visited the E15 site and found the soil type a fine 
sandy clay or fine sandy loam.  I changed the coefficients  at 1509 GMT to those for a very 
fine sandy loam; this produced reasonable soil moistures for the soil type.

The old coefficients in parameters 4 through 9 for step 136 of the program were: 0.95264, 
-6.7859, 36.224, -58.619, 25.073, 4.2278

The new coefficients are: 10.241, -27.943, 49.523, -12.648, -52.643, 38.054

SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect
DataStreams:sgp5ebbrE26.a1, sgp15ebbrE26.b1, sgp30ebbrE26.b1
Description:
In a trip to E26, I found that a bad spark gap through which the barometer was powered was 
causing pressure measurements to be incorrect.  The pressure readings oscillated with 
the voltage of the EBBR battery.  During daytime the voltage and thus the pressure would 
increase and vice versa during dark hours.

Apparently only the positive side of the power supply was properly connected through the 
spark gap and thus the voltage received by the pressure sensor was lower than required to 
power it properly.  Under this condition the perssure measurement varies with voltage 
level.  The pressure measurements therefore had a diurnal signature and usually were 
incorrect.  

The decreased pressure during most times would cause latent heat flux to be slightly 
overestimated and sensible heat flux to be slightly underestimated.
