SGP/QCRAD/E10 - Tracker failure
DataStreams:sgpqcrad1longE10.c2
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.

SGP/QCRAD/E10 - Noisy upwelling longwave
DataStreams:sgpqcrad1longE10.c2
Description:
Upwelling Infrared irradiance signals noisy resulting from problems with pyrgeometer 
signal cable connections.

Subject:
SGP/QCRAD/E10 - Noisy upwelling shortwave flux
DataStreams:sgpqcrad1longE10.c2
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.
