SGP/SIRS/E37 - Instrument problem
DataStreams:sgpsirs20sE37.a0, sgpsirsE37.b1
Description:
The short_direct_normal value is having some issues.  Data is missing starting 0123 GMT on 
6/30 through current.  Data is either close to 0 on clear days or not following normal 
trends prior to the aforementioned period.  down_short_diffuse_hemisp is also suffering 
from some issues.  

Problem looks to have started on 6/17, but may have started earlier than that.

are generally unaffected by such tracker failures.

possible incoming radiation) that were eventually attributed to a bad instrument cable 
connection.

10 to 100% of any given day.

Description:
Shading of the PSP radiometer occurred after sunrise each day of the reported date period, 
during the time period between 1215 and 1300 UTC.  Issue is present in the downwelling 
shortwave hemispheric variable.  The shading was caused by the the presence of an antenna 
that was later relocated. Data to be reprocessed and designated as missing (-9999) for 
the affected time period each day (except where NIP is greater than 150 w/m^2).
