Subject:
NSA/GNDRAD/C1 - Upwelling PIR ventilator fan failure
DataStreams:nsagndrad60sC1.b1, nsagndrad20sC1.a0
Description:
The PIR exhibited a positive bias of approximately 6 W/m2 compared to the upwelling IRT 
due to ventilator fan failure.  Thus, the up_long_hemisp, data stream is high by about 6 
W/m2.    
   
Bias is not consistent and depends on atmospheric conditions. Either disregard the 
up_long_hemisp data or use the IRT for an estimate of the up_long_hemisp values during this time 
period.
