Usage
-----
The ready-to-use arts xml files (formatted in ArrayOfGriddedField4) are stored under this path. Please use only the "*.xml.gz" files and ignore potential "*.temp" files.

OR

If you want to convert the ECMWF profile datasets by yourself to the ArrayOfGriddedField4 format, please follow these steps:
1) Download the original files from the NWP SAF wep page
2) Extract the downloaded file 'profiles137.tar.gz' to this path.
3) Compile "extract_arts_l137.f90" with your favourite FORTRAN compiler (e.g. f95)
4) Run the compiled output file
5) Run "ConvertCompactAtm_ArrayOfMatrix-to-ArrayOfGriddedField4.arts" with your arts distribution
