[gdal-dev] Metadata exceeding 32000 bytes cannot be written into GeoTIFF....

[Even Rouault]

Yes, there's this limitation to 32kb for the metadata stored in the 
GDAL_METADATA TIFF tag. I'm not sure where this comes from. I think this 
could probably be raised. Could you open a ticket about that ?

In the meantime, you could do

gdal_translate -a_srs EPSG:4326 -strict 
NETCDF:MITO_20210713_20210713T00.nc:V temp.vrt

then with a text editor edit temp.vrt to remove metadata items you don't 
need

and then

gdal_translate temp.vrt /Users/lollo/Desktop/TESTMITO/V.tiff
