ecmwf_wps_templates

These are the required templates for converting the ECMWF ERA-Interim data to WRF intermediate format with ungrib.exe and calc_ecmwf_p.exe.

Use the METGRID.TBL.ARW from the WPS source code and place it in a templates subdirectory of the convert_files.slurm directory as METGRID.TBL.

Also copy the Vtable.ERA-interim.ml file from the WPS source code and place it in the same templates subdirectory.

Finally, copy the namelist.wps file below into the templates directory too. You will need to adjust the number of nests, the start and end dates (ensure the start_date and end_date years match those which are replaced in the convert_files.slurm). The location of the geog_data_path will also need to be adjusted to suit your setup.
