Map NWP outputs to Satellite Imagery #20

Detailed Description

Courtesy @JackKelly but satellite imagery seems very useful for predicting PV output, and to go out more than a few hours, such as day ahead, etc. the actual satellite imagery isn't very useful. Instead, we could try to map from the NWP outputs to Satellite imagery.

In this repo, it could be similar to the data assimilation model, in that it takes the NWP output on one graph, and then maps that to the new graph that is the native satellite resolution over areas of interest, and maps down to the 12 satellite channels for EUMETSAT for example.

Context

There has been other work, I think detailed in other issues, that maps from NWPs to sub-grid outputs, like precipitation rate, so it seems like it should be possible.

Nice!
