Subject:
NSA/MWR/C1 - Reprocess: incorrect calibrations
DataStreams:nsamwrlosC1.b1, nsamwrlosC1.00, nsamwrlosC1.a1
Description:
MWR #17 was placed in service while MWR #20 was being repaired by the manufacturer.  The 
data need to be reprocessed with calibration coefficients appropriate for this instrument.
Suggestions: 
Measurements:nsamwrlosC1.a1:
  • Mean 23.8 GHz sky brightness temperature(tbsky23)
  • Blackbody kinetic temperature(tkbb)
  • Time offset from base_time(time_offset)
