SGP/SIRS/E9 - Downwelling SW cable problem
DataStreams:sgpsirsE9.00, sgpsirsE9.b1, sgpsirs20sE9.a0
Description:
The down_short_diffuse_hemispheric data were erratic beginning 0109 GMT March 27 2007.  
Found rodents had chewed DD cable.  Repaired April 3rd 1625GMT.

Data are not recoverable. However, it can be reconstructed using the following shortwave 
instrument relationship on a minute by minute basis:

SGP/SIRS/E7 - SIRS Power supply problems
DataStreams:sgpsirsE7.00, sgpsirsE7.b1, sgpsirs20sE7.a0
Description:
Power supply problems to SIRS datalogger resulted in logger voltage dropping below minimum 
for operation.  During these time ranges the datalogger was either not operating or 
operating intermittantly as battery voltage would go above and below logger voltage threshold 
of approx 9VDC.
