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 29r2

IFS is the current NWP model running operationally at the ECMWF. The global fields are described on lon lat coordinates with 60/91 vertical eta levels. 2006 is run by UiO with IFS Cycle 29r2 run on T319 (0.5625^o~50km). The Unified EMEP model can run on lon lat, but for comparison studies some dataset has been created for the EECCA area by interpolating to polarstereographic projection (50x50km²,20 sigma levels).

IFS 36r1

IFS is the current NWP model running operationally at the ECMWF. The global fields are described on lon lat coordinates with 60/91 vertical eta levels. 2008 has been run with IFS Cycle 36r1 on T799 (0.225^o~25km) taking out the levels 24 to 60 (87hPa-1013hPa).

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)
