Interactive program to convert longitude/latitude coordinates to EMEP grid cells and vice versa. Just type your numbers in the corresponding fields below:
Fortran library for EMEP grid interpolation and coordinate
conversion from the EMEP grid to longitude/latitude including
documentation: interpol.tar.gz
The freely available program Proj.4 can also be used to convert
from our projection to a large range of other projections. Please use the following proj-parameters:
# earth radius is 6370/50=127.4
proj +ellps=sphere +a=127.4 +e=0 +proj=stere +lat_0=90 +lon_0=-32 +lat_ts=60 +x_0=8 +y_0=110
Text file containing geographical co-ordinates
and area of each grid cell:
EMEPgrid.data (zip-file)
or EMEPgrid.txt.gz (size 953 kB)
Please note that the files are not yet updated for the extended
50 km grid, i.e. grid cells with j > 122 are currently not listed in
the files.
Text file defining the
fraction (in percent) of grid cells belonging to a particular country:
emep50official_country_grid_fraction.txt The file structure is the following: EMEP country codes, EMEP grid x coordinate, EMEP
grid y coordinate, fraction of country within grid cell. (Last update:
26.11.2008, including the extension of the EMEP domain.)
Text file linking EMEP ISO codes to EMEP
country/area codes and country/area names:
