SGP/EBBR/E15 - Wind Direction 10 Degrees Low

The wind direction at E15 EBBR was 10 degrees low for the period (since

flows.  However, this did not affect sensible and latent heat fluxes outside
the error of the EBBR system.

SGP/EBBR/E8 - Pressure Sensor Measurements Incorrect

The EBBR barometer did not agree with the SMOS at
all times.  However this problem only rarely affected the 
sensible and latent heat flux values. 

Replacement of the barometer on 29 july 2003, 12 aug 2003,
and 26 aug 2003 caused some obvious disruption in data flow.

After a while, the teflon slides on the AEMs warp from

This happened at E7 EBBR.

The net radiometer top dome was punctured by migrating birds.  This alone does not cause

SGP/EBBR/E27 - Missing data during system update

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/E12  - Water in Net Radiometer, Surface Fluxes 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

day and too small at night.

SGP/EBBR/E26 - AEM Home Signals Incorrect, Surface Fluxes Incorrect

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.

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.

SGP/EBBR/E12 - Pressure Sensor Measurement Scales With Battery Voltage

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.
