Subject:	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.

Subject:	SGP/SIRS/E37 - Tracker and NIP repairs
DataStreams:	sgpsirs20sE37.a0, sgpsirsE37.b1
Description:	The solar tracker at this site was replaced; communication problems with the replacement tracker were performed 7/2/12; NIP repair performed 7/9/12. Data for direct normal (NIP) and diffuse (8-48)are incorrect and nonrecoverable during affected period. Longwave data is generally unaffected by such tracker failures.

Subject:	SGP/SIRS/E35 - Upwelling longwave resistor problem
DataStreams:	sgpsirs20sE35.a0, sgpsirsE35.b1
Description:	up_long_hemisp was missing or showing intermittent spikes for the specified period. OPS discovered a bad UIR resistor and replaced it with new resistor.
