NSA/MET/C1 - CMH and 10m winds failure
DataStreams:nsametC1.b1
Description:
At 0513GMT on 1/23 the atmos_pressure and CMH - temp, RH, DP & Sat. VP changed abruptly to 
unlikely values. The 10m winds failed at 1420GMT.

The CMH was repaired on 02/04/2010 at 2254GMT and the 10m winds sensor was replaced on 
02/05/2010 at 2100GMT.

NSA/SKYRAD/C1 - Frosting/Condensation
DataStreams:nsaskyrad20sC1.a0, nsaskyrad60sC1.b1
Description:
The down_long_hemisp1 varied up to 40 W/m^2 higher than down_long_hemisp2 during the 
affected time periods. Cold temperatures reported by the IRT suggest the issue is with PIR1.  
Icing or frost on PIR1 or within the ventilator may be to blame but ops reports can't 
substantiate this. Data from PIR1 should be avoided during these suspect time periods.
