Alternate bathymetry data

Hello,

I’m trying to use the GEBCO bathymetry dataset instead of the default set by:

elevfile (ifile) (default=$OCDATAROOT/common/ETOPO1_ocssw.nc) = global elevation netCDF file

I have downloaded the GEBCO_2020.nc file from the GEBCO webpage but the format is different from ETOPO1_ocssw.nc (ETOPO1 datasets are ‘height’ and ‘water_surface_height’ and GEBCO just has ‘elevation’, the metadata formats are also different). Is there a way to reformat the GEBCO file so that it can be opened by specifying the elev product?

Thanks,
Alex

It's a *little* more complicated than a simple reformat...but not much.
I could explain, but easier to just give you the file that will be used in our next reprocessing :grin:

It will soon be available with SeaDAS (our next release will be a beta for v8.0), but until then you can grab it from here:
