Subject:
TWP/MWR/C2 - thermal instability
DataStreams:twpmwrtipC2.a1, twpmwrlosC2.b1
Description:
The MWR required an unusually long time to reach thermal stability after a 4-day outage 
due to a power failure that damaged the blower/heater assembly. Also during this period, 
the heater, which had been replaced, appears to have been on continously, causing the data 
to be inappropriately flagged.
Suggestions: 
Measurements:twpmwrtipC2.a1:
  • 31.4 GHz sky signal(tipsky31)
  • 23.8 GHz sky signal(tipsky23)
  • Water on Teflon window (1=WET, 0=DRY)(wet_window)
  • Temperature correction coefficient at 23.8 GHz(tc23)
  • Noise injection temp at nominal temperature at 23.8 GHz(tnd_nom23)
