Subject:
SGP/QMEMWRCOL/B6 - Metadata error
DataStreams:sgpqmemwrcolB6.c1
Description:
This VAP includes a field named "likely_clouds" which, according to the metadata, can 
assume the value of 0 (clear) or 1 (likely cloudy). However, this field often contains the 
value 3.

Inspection of the code indicates that if there are layers in the atmosphere where the RH 
is above 95% and the liquid water path is above 60 g m-2, then the field "likely_clouds" 
contains a 1.  However, if there are levels where the RH is above 95% and the liquid water 
path is below 60 g m-2, then "likely_cloudy" was set to 3 instead of 1.  The only time 
this field is set to 0 (clear) is if there are no levels in the atmosphere where the RH is 
greater than 95%.
Suggestions: 
If "likely_clouds" is 1 or 3, there are likely clouds in the column overhead.
