 Discussion of Problem:   This sounding was done in RESEARCH mode for
                          both thermodynamic as well as wind data.  The
                          normal mode is to for RESEARCH winds only.  As
                          a result, both the ascending and descending
                          flights of the sonde are included in the data
                          file and none of the data are smoothed or
                          filtered.  

 
Other observations/measurements impacted by this problem:  I think that
                          some of the radiation codes that use the sonde
                          data as input don't handle the descending samples
                          well.  I'm not sure which ones may be affected.


Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)  Users should be notified and,
if (and only if) requested, the sounding could be reprocessed either using
the software developed at the EC or the digi-CORA.
