NSA/MWRRET/C1 - Sonde input processing issue

There was a data processing issue with the nsasondewnpnC1.b1 datastream during these 
periods.  As a result, the nsamwrret1liljclouC1.c1 files were sometimes processed without any 
sonde data available as an input to the VAP.  The physical retrievals, phys_lwp and 
phys_pwv, require sounding data and were not calculated for these files.  This also means that 
the be_lwp and be_pwv from these files only contain values from stat2_lwp and stat2_pwv.

The phys_lwp and phys_pwv values are already set to -9999 in these files, but users 

should be aware that these variables will eventually contain useable data once these 
files are reprocessed with the available sounding data.
