It has been noted by Barbara Pirsher (Wegener Center/UCAR) that the 'wet' temperature and pressure values from the 'wetPrf' profiles are not consistent between missions. This is due to the fact that different background model data were used in the 1D-VAR assimilation that is used to compute these profiles. This table shows the model currently used for each mission available on the CDAAC web site. We plan on using the ERA-40 interrim reanalysis for future reprocessings.
