@sbmeteo@mastodon.social there's a note that the poster is a translation of the WMO cloud identification guide but the photos were provided by DWD. https://cloudatlas.wmo.int/en/cloud-identification-guide.html seems to be the source edit: https://cloudatlas.wmo.int/fr/cloud-identification-guide.html may be the version you can reuse most easily ;) @DeutscherWetterdienst@social.bund.de
