I am reposting from GIS Stack Exchange as here might also be someone who might help:

I have a precipitation GRIB2 file obtained at EUMETSAT H-SAF I am able to decode it to ascii but the software I am using (gdal, ArcMap,...) does not recognize the projection (in the title) so I am not able to properly project to Web Mercator for example. So can anyone please suggest software that preferably works on Ubuntu and projects either grib2 files to other projections or is able to recognise the projection from decoded ascii.

  • $\begingroup$ I believe GrADS was solid at changing projections and was centered around grib2. But it's been so long, not sure if it's exactly what you need. $\endgroup$ – JeopardyTempest Nov 23 '18 at 8:51

    $\begingroup$ @JeopardyTempest I'll check, any suggestion is appreciated as I've been loosing my mind for 2 days now. $\endgroup$ – Alešinar Nov 23 '18 at 9:01

    $\begingroup$ This is just a stereographic projection clipped with a rectangular neatline: geophysics.eas.gatech.edu/classes/Intro_GMT/gmt_www/gmt/doc/… Can your software do oblique azimuthal projections at all? $\endgroup$ – Spencer Nov 23 '18 at 16:14
  • $\begingroup$ @Spencer yes it can. Thank you for your effort I found a solution and will post as answer $\endgroup$ – Alešinar Nov 26 '18 at 10:02

The product (H-SAF 05) manual stated the datasets are in the projection mentioned in the title. EUMETSAT user support answered me the datasets use a polar stereographic projection with 25-75°N lat, 25°W- 45°E long.
