Dear sir
I would like to use etopo2. I found only GMT format of etopo2 "etopo2.grd".
However, the netcdf format of etopo2.grd is quiet different from etopo5.cdf and etopo2.grd does not look like two dimensions unlike etopo5.cdf.
Could you suggest me how to use etopo2.grd in ferret?
or Is there etopo2.nc or etopo2.cdf available anywhere?
Best Regards
