Correct grid file for ICON grib files

Added by Maik Gottschalk about 3 years ago

Hi Ralf,

following your valuable support given at

https://code.mpimet.mpg.de/boards/1/topics/8094?r=8095

I'm trying to decode ICON grib files obtained from

https://opendata.dwd.de/weather/nwp/icon-eu/

For ICON and ICON-D2 the relevant grid numbers can successfully be determined by 'sinfon' (26 and 47, respectively).
Unfortunately, for ICON-EU no grid number is returned.

I'd be grateful if you could point me in the correct direction on how to determine the corresponding grid number.

--Maik.

Read the following (https://code.mpimet.mpg.de/projects/cdo/embedded/index.html#x1-310001.4.3)
Someone must have made a grid file for this data. If they have not, you will have to make one yourself. Read all of section 1.4 (https://code.mpimet.mpg.de/projects/cdo/embedded/index.html#x1-190001.4) then read Appendix D (https://code.mpimet.mpg.de/projects/cdo/embedded/index.html#x1-909000D).

this is the official grid resource http://icon-downloads.mpimet.mpg.de/dwd_grids.xml

you should find the grid there if you have the right ID I think

more public information about ICON can be found here: https://code.mpimet.mpg.de/projects/iconpublic/wiki
