Subject:	NSA/SKYRAD/C2 - Instrument grounding problem
DataStreams:	nsaskyrad20sC2.a0, nsaskyrad60sC2.b1
Description:	The down_long_hemisp1 was often 50 W/m^2 greater than down_long_hemisp2 during the suspect times. Data logger grounding issues were addressed by site ops and have corrected the problem.

Subject:	NSA/SKYRAD/C2 - Suspect PIR1
DataStreams:	nsaskyrad20sC2.a0, nsaskyrad60sC2.b1
Description:	PIR1 (down_long_hemisp) data are suspect during these time ranges due to the large differences between PIR1 and PIR2 (i.e. greater than 10W/m2). Maintenance on 12/26 indicated a failed ventilator heater connector on PIR1. After 12/26 PIR1 and PIR2 returned to tracking each other within 10W/m2 as typical.

Description:	On 7/20/2011 2211GMT Ops replaced the Gndrad upwelling shortwave instrument (PSP) but the calibration coefficients weren't changed until 07/25/2011 1842GMT. The up_short_hemisp data were reprocessed and archived in September 2011.

DataStreams:	nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
Description:	On 7/20/2011 starting 2229GMT ops replaced the Skyrad shortwave instruments (PSP/8-48/NIP) corresponding to the datastreams (down_short_hemisp, down_short_diffuse_hemisp, short_direct_normal) but the calibration coefficients weren't changed until 07/25/2011 1842GMT.

DataStreams:	nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
Description:	During a power outage the downwelling diffuse 8-48 and the downwelling shortwave direct were incorrect. The IRT was also affected during this time period.

DataStreams:	nsaskyrad60sC1.b1, nsaqcrad1longC1.c1
