Subject:
NSA/GNDRAD/C1 - power outage affecting some GNDRAD sensors
DataStreams:nsagndrad20sC1.a0, nsagndrad60sC1.b1, nsagndradC1.00
Description:
During the power outage the upwelling global measurement from the PSP instrument shows a 
slight increase from -5 to +0 W/m2.  This is due to removal of thermal offsets induced by 
the AC heater during the power outage.  This heater is installed within the PSP 
ventilator - it is necessary for the NSA/C1 climate.
The upwelling longwave PIR instrument is unaffected due to case and dome temperature 
corrections.
The IRT is AC powered and was not operational during this time period.
