1D-Var v1.1.1 has been released

A new version (version 1.1.1) of the 1D-Var package has just been released and uploaded to the NWPSAF web site ( nwp-saf.eumetsat.int ). This release was necessary after a bug was found in the previous NWPSAF 1D-Var package (version 1.1) which affected microwave retrievals that included the liquid water path. In the 1DVar source code file NWPSAFMod_LiquidWater.f90 the order of the arguments to the function Layers_to_LWP was incorrect. The bug has now been fixed. Also, the sample test data for SSMIS_43L ( for RTTOV11 / RTTOV12 and ifort / gfortran) were affected by the bug and these have been corrected.
