Meteorological input files
Currently all meteorological input files are available on stallo. The input files are processed from different NWP models: Parlam-PS (old Hirlam version), Hirlam20 (Hirlam version 7.1.3), IFS, Hirham (Hirlam version) and are available on NetCDF format.
Hirlam
The EMEP-H20 dataset is made of Hirlam version 7.1.3 runs on extended EMEP area covering EECCA countries (370×380 gridboxes) with rotated spherical coordinates (0.2^o×0.2^o~20x20km²) on 40 eta levels interpolated to polarstereographic coordinates (50x50km² or 25x25km²) on 20 vertical sigma levels. A EMEP-H10 dataset (only for 2006!) is also made of Hirlam version 7.1.3 on a reduced EMEP area (covering central Europe)(500×500 gridboxes) with rotated spherical coordinates (0.1^ox0.1^o~10x10km²) on 40 eta levels interpolated to polarstereographic coordinates (10x10km²) on 20 vertical sigma levels.

IFS
IFS is the current NWP model running operationally at ECMWF. The global fields are described on lon lat coordinates. 2006 is received from UiO, but 2008 has been run on ECMWF recently.

Hirham
Parlam-PS
The EMEP-PPS is a special version of the HIRLAM-3 created in 2000 covering the past EMEP grid (170×133) on a polarsterographic projection. These meteorological input files are both available on a special felt-format specially created as Unified EMEP model input, but has been also converted to NetCDF format (can run Unimod with both input formats).
Felt format is available from:
/global/work/mifapw/emep/Data/EMEP/metdata/
for the following years: 1990, 1995-2006 (+200701)
The following is describing the files on NetCDF format.
