203	POD missing from BUFR	Dave Offiler	Dave Offiler	"While setting up reflections flagging for Estel's test data - which involves decoding the UCAR BUFR files to netCDF (bufr2ropp) and re-encoding to BUFR (special version of ropp2bufr which hard-sets
the PCD reflections flag), and a validation by comparing decoded dumps of the UCAR and flagged BUFR - I found (for the tested case) that both GPS and LEO POD (pos+vel) were missing from the flagged BUFR but present (or at least not obviously fill values) in the original. The overall refractivity quality index parameter was similarly missing (zero in the original). As these don't affect Sean's use of the BUFR for assimilation trials, I just continued with the processing.

Both bufr2ropp & (modified) ropp2bufr tools are from the current trunk [2443] (essentially v4.0)

The intermediate netCDF file needs checking to see whether these parameters are present or missing, which will inform as to whether it is the decoder or encoder at fault. Or even if the original values are invalid. Inappropriate valid range might explain the POD going missing, but unlikely for the Ref.QI."	defect	closed	normal	5.0	ropp_io	4.0	fixed	BUFR
