I know how to import rasters. Let me be more specific in my question. Do I download and import their “grid-registered netCDF”, “grid-registered georeferenced tiff”, “cell-registered netCDF”, or “cell-registered georeferenced tiff”?
A reason for my confusion was that I assumed one could only import images as rasters, and these didn’t seem like images to me (though I’m probably wrong). I’m also confused because, if it’s already an image, then that’s what I want. In general I am very easily confused.
