Re: Reprojecting S3B-OLCI Level-2 Reduced Resolution to GeoTIFF

The coordinate arrays are recognized as "geolocation arrays": ``` gdalinfo NETCDF:"S3B_OLCI_ERRNT.20250101T164657.L2.IOP.NRT.nc":/geophysical_data/bb_443 ... Geolocation: SRS=GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS 84",6378137,298.257223563,AU...

Re: VIIRS Snow Cover L3 user guide wrong CRS information?

I've made a note of this and will try to get this fixed in a future GDAL, this is presumably a common way to georeference with the XDim/YDim coord values. Just generally, I would suggest reporting examples like this directly as issues on the repo, or ask on gdal-dev, there's no end to the variations...

Re: SST

R can lazy load from netcdf via URLs in the usual ways, here the {terra} package leverages GDAL to do the work (I'm not using your dataset exactly but happy to rejig if you want to share specifics): ``` library(terra) url <- "https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-protecte...
