[model] NWP model data

[ofuhrer]

@mchaamsler Seems like a lot is already there except for NWP model data. Would be great to start filling in this category as well!

Hi @ofuhrer, sure - we are ‚silent live‘ since yesterday. Will be back at MCH by August 2.

@Lukimch from the OGD@MeteoSwiss project core team is your lead link for ‚model data‘.

I give you write access to the repo, and you are free to proceed.
