Subject:
SGP/MWR/C1 - Valid LWP > 1mm excluded from 5 min avgs
DataStreams:sgp5mwravgC1.c1
Description:
The limit of maximum valid liquid water path was set at 1 mm.  Although
this limit was selected 'conservatively' so as to definitely flag
precipitation-contaminated data in the 20-second (sgpmwrlos) files,
the effect has been to exclude valid liquid water paths greater than 1
mm from the 5-minute averages (sgp5mwravg).

The maximum limits for precipitable water vapor (PWV) and liquid water
path (LWP) have been removed, and the averaging algorithm instead
excludes data on the basis of the brightness temperature flags.  These
flags are set below a minimum of 2.75 K (cosmic background) and above
a maximum of 100 K (precipitation).
Measurements:sgp5mwravgC1.c1:
  • Averaged total liquid water along LOS path(liq)
  • Standard deviation about the mean for the total liquid water amount(liq_sdev)
