[gdal-dev] Reading a DODS file from GrADS Data Server

I currently have GDAL 2.2.3. `gdalinfo --formats` includes "DODS -raster- (ro): DAP 3.x servers". However, if I download a small MERRA-2 DODS file from NASA with this OPeNDAP URL

wget 'http://opendap.nccs.nasa.gov/dods/merra2_gmi/tavg1_2d_aer_Nx.dods?pm25[1:3][1:3][1:3]' -O out.dods

then `gdalinfo out.dods` yields "ERROR 4: `out.dods' not recognized as a supported file format." Sadly, this OPeNDAP server software, namely GrADS Data Server, doesn't seem to support any binary output format other than DODS.

Any idea what's going on? Does this work with a newer version of GDAL?
