SGP/5MWRAVG/B1/B4/B5 - Valid LWP > 1 mm excluded from 5 min avgs

Note: These data have not been and will not be reprocessed.  The MWRAVG VAP has been 
retired.

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 following actions are recommended:
1) the maximum limits for precipitable water vapor (PWV) and liquid water path (LWP) be 
removed and, 2) the averaging algorithm instead exclude 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).
