ICON Forecasts

Open sergejlazuk opened this issue 1 year ago • 2 comments

Hi and thx for this cool package. I believe it would benefit if you could more explicitly provide a way to download ICON forecast. It could then be used as a replacement for many of us who currently use GFS or ECMWF forecast? The closest to what I was looking for I found in Chapter on Raster Data, as readDWD.grib2. I think ICON forecast data deserves its own chapter and maybe specific methods just for working with forecasts series? Thx, Sergej

Hey Sergej,

you're welcome :)

Can you provide a link? Then I'll see what I can do (not this week anymore, stuff's crazy right now)

There is one file per hour per variable containing all LON/LAT gridpoints. I tried it myself today, I had to use wgrib2 to extract the data on windows.

Mit freundlichen Grüßen/Best Regards S. Lazuk

It's been way too long, sorry, but here is a new section on the website: https://bookdown.org/brry/rdwd/raster-data.html#icon-eu

The grib2 function reads the data just fine. For further analysis, feel free to re-open the issue and suggest more code. Since I don't work with forecast data, there is not much I can contribute...
