Subject:
NSA/MWR/C1 - High noise in 23.8-GHz channel
DataStreams:nsamwrlosC1.b1, nsamwrtipC1.a1
Description:
Starting approximately on February 13 the MWR experienced high level of noise in the 23.8 
GHz channel. The spikes became more prominent around Feb 17 and increased after that date 
as well. The cause of the interference was identified as the nearby MWRP on Oct 13 and 
the instruments were realigned.
Measurements:nsamwrlosC1.b1:
  • 23.8 GHz sky signal(sky23)
  • MWR column precipitable water vapor(vap)
  • Sky brightness temperature at 23.8 GHz(tbsky23)
nsamwrtipC1.a1:
  • Total water vapor along zenith path using tip-derived brightness temperatures(vaptip)
  • 23.8 GHz sky signal(tipsky23)
  • 23.8 GHz sky brightness temperature derived from tip curve(tbskytip23)
