I have not used NetCDF with MapServer, so take all of my response with

Yes, GDAL can read NetCDF, but remember, NetCDF is a generic data
format, not a geographic data format. You can store geographic data in
it, but it can be any kind of hierarchical data. It would be your
responsibility to read your data using GDAL, and then, use GDAL to
convert its relevant portions (the geographic portions) into one of
the many formats that MapServer can understand.

You are responsible for reading the NetCDF data using GDAL, extracting
the geographic portions, and converting them. GDAL is basically a
converter that can read in various formats and write out various
