NSA/MWR/C2 - Occasional thermal instability
DataStreams:nsa5mwravgC2.c1, nsamwrlosC2.b1, nsamwrtipC2.a1
Description:
Between 7/1 and 7/15 the radiometer experienced a few days of thermal instability. From a 
review of the data it doesn't appear that the instability has had any major effect. It is 
not possible to quantify in detail the effect of the instability due to the lack of 
radiosonde sounding,  however users are cautioned that a higher uncertainty may be affecting 
these data.
Measurements:nsa5mwravgC2.c1:
  • Sky brightness temperature at 31.4 GHz(tbsky31)
  • Sky brightness temperature at 23.8 GHz(tbsky23)
  • Averaged total liquid water along LOS path(liq)
