Subject:
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.
