DataStreams:sgpsirsE5.b1, sgpsirsE5.00, sgpsirs20sE5.a0
Description:
The PSP dome was dirty.  The magnitude of differences from derived 
             vs. measured values of downwelling shortwave were about 75 W/m^2. 
             Preventative maintenance on 4/21 cleaned instruments but they 
             became dirty again immediately afterward and continued to be
             so until the next PM on 5/5.
Suggestions: 
Use data with caution.  NIP may have been affected during the same period.
