Recently, i downloaded this NetCDF4 .nc4 file from OCO-2 (Orbiting Carbon Observatory) from NASA and i'd like to Make a Raster Layer using Multidimensional Tools in ArcGIS Pro (1.1). But when i try to create the raster layer i can't choose latitude and longitude as dimensions only the band dimension and sounding_id
The Description i received from Panoply (NetCDF Reader )for this data is the following.
