Subject:
SGP/EBBR/E12  - Water in Net Radiometer, Surface Fluxes Incorrect
DataStreams:sgp5ebbrE12.b1, sgp15ebbrE12.b1, sgp30ebbrE12.b1
Description:
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.
Suggestions: 
There is no work around for this problem, as the Bowen ratio technique
is dependent on the accuracy of the net radiation value.
