On a higher level of access note, netCDF data can also be accessed with GMT.jl, (either from GMT itself or its GDAL bridge), And it’s mapping capabilities are … good.
For example, to display the SST layer of an .nc file in the OceanColor site, one can do
using GMT
# file address and SUBDATSET selection
julia> fname = "/vsizip/vsicurl/https://oceandata.sci.gsfc.nasa.gov/cgi/getfile/SNPP_VIIRS.20191001_20191031.L3m.MO.NSST.sst.9km.nc=gd?NETCDF:\"SNPP_VIIRS.20191001_20191031.L3m.MO.NSST.sst.9km.nc\":sst";
# Remotely read just the SST layer
julia> G = gmtread(fname, grd=true);
# and display it
imshow(G, region=:global, projection=:Mollweide, frame=:ag, title="SST - September 2019", figsize=15, colorbar=true, coast=true)
