ICON model data

I am interested in checking out DWD's ICON model output, especially the higher-resolution ICON-EU nest. The new "DWD" option among the "Grib data source" in the Weather panel suggests that it would be available there.

However, when I select the DWD button nothing happens. Are other having same problems or not? The other grib data sources seems to output as expected.

Will I get ICON Grib downloads here as expected?

I haven't finished implementing it yet. You can download directly from the web at

Re: ICON model data

I could only find data split up per parameter and time frame. I was interested in wind data and in order to build a grib from separate u- and v- components and for each hour, this shell script worked for me:

# Script to build 10m wind grib at all available forecast hours from u and v component wind at DWD web site
RUNTIME="$(printf %02d $((((24+$(date -u +%k)-3)/3)%8*3)))"
wget -r -l1 -nH --cut-dirs=100 --no-parent -A.bz2 --no-check-certificate https://opendata.dwd.de/weather/icon/eu_nest/grib/$RUNTIME/u_10m/
wget -r -l1 -nH --cut-dirs=100 --no-parent -A.bz2 --no-check-certificate https://opendata.dwd.de/weather/icon/eu_nest/grib/$RUNTIME/v_10m/
bzip2 -d *.bz2
cat *.grib2 >icon.grb2
rm *.grib2

I am sure there are a lot of better ways of doing it but hope this might help anyone with similar interest.
