NSA/SKYRAD/C1 - Tracker inoperative
DataStreams:nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
Description:
Tracker stopped working at this site during the time range specified. Reason for failure 
is unknown.  Tracker power cycled and restarted by maintenance 06/30 2008 1740 GMT.

The short_direct_normal (NIP) and down_short_diffuse_hemisp (8-48) data are bad during 
this time.  Data are not recoverable.

NSA/SKYRAD/C2 - Station noise problem
DataStreams:nsaskyrad20sC2.a0, nsaskyrad60sC2.b1
Description:
From 8/18 through 8/20 the logger battery voltage (vBatt) periodically jumps in voltage 
with noise on all differential measurements.  The qc fields caught most of the 
down_long_hemisp MAX failures but the bad short_direct_normal, down_short_hemisp and 
down_short_diffuse_hemisp values were not flagged.

Noise returned on 8/22, 8/25-26 and 8/27-28.

Site Ops checked and re-routed the Sky stand grounds on 8/21 and performed additional 
ground re-work on 8/28.  After that date, noise has not returned to the Skystand logger 
instruments.

NSA/GNDRAD/C1 - Upwelling PIR ventilator fan failure
DataStreams:nsagndrad20sC1.a0, nsagndrad60sC1.b1
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.
