Add preliminary support for FCI in Geo2Grid #651

Closed kathys closed 10 months ago

kathys commented 1 year ago

For the release of Geo2Grid Version 1.2, Graeme would like to add preliminary support for the Meteosat Third Generation Flexible Combined Instrument (FCI) imager.

A lot of the data we have available from the data center seems incomplete. I'm having trouble finding a whole time step. One thing to note is that the filenames currently look like this:

MTG-I1_FCI_true_color_20231201_114000_mtg_fci_fdss_1km.tif

Where "MTG-I1" is the platform/satellite name, "mtg_fci_fdss_1km" is the grid name of the native data.

@kathys what do you think about the filenames mentioned above? Do we put in the work to try to make these prettier for what we expect or do we leave them? If we leave them as they are and end up changing them in the future we may break (kind of) backwards compatibility with anyone depending on a specific style of filenaming.

@djhoese I think we should try to get these right now so that there will be as little change as possible in the future. What things are you concerned about that might change?

djhoese commented 10 months ago

I assumed MTG-I1 was incorrect, but it looks like "-I1" is actually part of the official satellite name so that seems OK. There are notes from the EUMETSAT folks in the Satpy reader that after operational status the platform/satellite name may change to "Meteosat-XX". So this may be a change users have to deal with.

The other concern is the "mtg_fci_fdss_1km" name in the filename, but this comes from the area (grid) name defined in the Satpy reader. Normally I try to make these human-readable and I'm not sure this one is...although it is very specific so maybe it should stay this way. I don't think I have an easy way to rename the grid name in Geo2Grid when it comes from the Satpy readers.

I think you have done the best with the filenames from what is known now. I would hate to try and predict what the Satellite name may change to after launch. I think you should go with what you have, and we can make decisions in the future if and when we need to.

Ok. I'm going to close this then and we can consider the initial "experimental" version of the "fci_l1c_nc" reader done.
