SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR 
Header

The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the 
EBBR 30 minute netcdf header have been incorrect from the beginning 
of processing the data into netcdf files.  The correct units are 
MJ/m^3/C.

qc flag being set.

However, this does not create any data quality issues.  The qc flag is
set just to provide an alert that the automatic exchange mechanism may have a problem; in 
this case data was not affected.

An electronics repair solved the problem.

SGP/EBBR/E22 - AEM Home Signals Too High

The AEM home signals were too large at times during the indicated period;
it has been determined by the vendor that this is usually caused by electrical noise in 
the vicinity. When the 30 minute data shows a home 30 signal of 35 or more, the bowen 
ratio, and sensible and latent heat flux 
measurements are incorrect 

Removing the jumper between 4L and AG on the CR10 and adding a jumper to Multiplexer 2, 
Set 6, between L1 and L2 fixed the problem.  The
vendor intends to make this modification to all EBBR systems as they return
for re-calibration.

SGP/EBBR/E8  - 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 
in the bottom dome, causing the net radiation measurements to be too large during the 
day and too small at night.

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/E22  - 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 
in the bottom dome, causing the net radiation measurements to be too large during the 
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.

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