Subject:
NSA/SONDE/C1 - RH sensor failure
DataStreams:nsasondewnpnC1.b1
Description:
It appears that one of the two RH sensors on this radiosonde was affected by ice after 
emerging from a low cold cloud.  As a result the reported RH values oscillate by about 10 
percent until the alternate heating cycle stops.  I suspect the lower value is more close 
to correct, but can't be absolutely sure.
Suggestions: 
No easy fix available.
Measurements:nsasondewnpnC1.b1:
  • Dewpoint Temperature(dp)
  • Relative Humidity (hybrid-b grid)(rh)
