Subject:
NSA/GNDRAD/C1 - power outage affecting some GNDRAD sensors
DataStreams:nsagndradC1.00, nsagndrad20sC1.a0, nsagndrad60sC1.b1
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.

NSA/GNDRAD/C1 - Incorrect calibration coefficients
DataStreams:nsagndradC1.00, nsagndrad20sC1.a0, nsagndrad20sC1.a1, nsagndrad60sC1.b1
Description:
BarrowC1, Gndrad. On Aug 11th the PSP-US was changed out and the Campbell program was 
changed to reflect this.  However, an old program that uses the 4 coefficient PIR cal factors 
was used. The PIR-UIR was not changed out, however, the logger program coeffs reverted 
back to the 4 Coeffcients.  The Eppley PIR-UIR coefficients for this S/N 30168F3 are :  
K0=0.0, K1(aka k)=.25253, K2= 1.0, K3=-4, Kr=0.0.
