Subject:
NSA/MWR/C1 - Spikes in air temperature readings
DataStreams:nsamwrlosC1.b1, nsamwrtipC1.a1
Description:
During this month there are occasional negative spikes in the Tkair variable. The problem 
may be corrosion in the temperature sensor or the infiltration of water from melting snow.
The dewblower was replaced and a new sensor installed
Measurements:nsamwrlosC1.b1:
  • Ambient temperature(tkair)
nsamwrtipC1.a1:
  • Ambient temperature(tkair)

Subject:
NSA/MWR/C1 - Incorrect brightness temperatures and retrievals
DataStreams:nsa5mwravgC1.c1, nsamwrlosC1.b1, nsamwrtipC1.a1
Description:
The brightness temperatures and retrieved PWV and LWP show a sudden jump and have values 
that are too high. The suddenly jump back to normal at around 1800 UTC. All other 
parameters seem reasonable so the cause of the jump may just be due to accumulation of either 
snow or melting ice on the radome.
Measurements:nsa5mwravgC1.c1:
  • Sky brightness temperature at 23.8 GHz(tbsky23)
  • Sky brightness temperature at 31.4 GHz(tbsky31)
  • MWR column precipitable water vapor(vap)
  • Averaged total liquid water along LOS path(liq)
nsamwrtipC1.a1:
  • 31.8 GHz sky brightness temperature derived from tip curve(tbskytip31)
  • Ambient temperature(tkair)
  • Total water vapor along zenith path using tip-derived brightness temperatures(vaptip)
  • 23.8 GHz sky brightness temperature derived from tip curve(tbskytip23)
  • Total liquid water along zenith path using tip-derived brightness temperatures(liqtip)
nsamwrlosC1.b1:

  • MWR column precipitable water vapor(vap)
  • Sky brightness temperature at 31.4 GHz(tbsky31)
