ROPP_FM data files for release version v10.0
-------------------------------------------

This directory contains a collection of data files used by ROPP_FM.

Notes on the data files in this directory:

bgr2009*.nc        - ECMWF short range forecast background profiles [91 level].
                     Available from ROM SAF archive http://www.romsaf.org/
ecmwf_*.nc         - ECMWF short range forecast background profiles [60 level].
FM_Scenarios.nc    - 5x FASCOD background profiles
ECMWF_*.nc         - Sample files containing 2D background fields for testing
                     the 2d operator

bgr2009*_iono.nc   - as XXXX versions, but including ionospheric parameters
                     to test ropp_fm_bg2ro1d -direct_ion.

bgr2009*_iono_ref.nc - reference versions of the above.

These files were created from ECMWF short range forecasts. The levels
are the ECMWF ones, called 'hybrid ECMWF' in order to indicate that
these are hybrid levels as used by the ECMWF model system (there might
be other NWP centres using hybrid vertical levels, with slightly
different definitions). 

There are also various reference files, against which the results of the tests
of the various ropp_fm tools and routines held in the ../tests directory and
routinely performed when building ropp_fm, will be compared.
