Subject:	SGP/QCRAD/E10 - Tracker failure
DataStreams:	sgpqcrad1longE10.s2
Description:	During the night of 11/05-06 2004 the tracker failed at this location. During CM on 12/01, power cycling returned the tracker to service. However, tracker was not properly tracking in the AM. Tracker failed again sometime near 01/01/2005. CM reloaded the tracker program and realigned the tracker on 01/26/2005 1600GMT correcting the problem. Documented in instrument DQR: D041206.1
Measurements:	sgpqcrad1longE10.s2: Irradiance, shortwave, direct normal, pyrheliometer(short_direct_normal) Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp) Irradiance, shortwave, downwelling, diffuse, hemispheric, pyranometer(down_short_diffuse_hemisp)

Subject:	SGP/QCRAD/E10 - Noisy upwelling longwave
DataStreams:	sgpqcrad1longE10.s2
Description:	Upwelling Infrared irradiance signals noisy resulting from problems with pyrgeometer signal cable connections. Documented in instrument DQRs D030110.37, D030110.36, D031027.1
Measurements:	sgpqcrad1longE10.s2: Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)

Subject:	SGP/QCRAD/E10 - Noisy upwelling shortwave flux
DataStreams:	sgpqcrad1longE10.s2
Description:	Beginning 6/22, upwelling shortwave values frequently dropped well below 0 W/m^2 (occasionally dropping below -50 W/m^2) during the nighttime hours. Daytime values were excessively high and noisy. Instrument wiring was suspected and was corrected 07/02/2003. Documented in instrument DQR D030701.1
Measurements:	sgpqcrad1longE10.s2: Irradiance, shortwave, upwelling, hemispheric, 10 meter(up_short_hemisp)

07/01/2000	0000	01/01/2001	0000	Suspect

Subject:	SGP/QCRAD/E10 - Upwelling LW Tc/Td/flux questionable
DataStreams:	sgpqcrad1longE10.s2
Description:	Case and dome temperatures for upwelling longwave flux are sporadically questionable during this period corresponding to additional noise in the longwave fluxes. No instrument DQRs exist documenting this problem.
Measurements:	sgpqcrad1longE10.s2: LWupTc LWupTd Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
