Convert latlon to gaussian grid

Added by Oliver Angelil over 7 years ago

File is attached.

How can I convert the attached latlon grid to a gaussian grid (and keep the 46 x 59 dimension), so that I can apply the "uv2dv" operator to it.

Thanks,
Oliver

This seems to work:

cdo intgridbil,r59x46 latlon_grid.nc latlon_grid2.nc

Actually the above was incorrect. Still looking for help.

Also, what is the difference between:

cdo intgridbil,t159grid ifile.nc ofile.nc

and, for example...

cdo remapbil,t159grid ifile.nc ofile.nc

(assume I have a file with data over the whole world, not just Australia like I attached earlier).

Hi Oliver,

I would expect that intgridbil is doing the same as remapbil. It is not documented anymore and seems to be really old. I would recommend to use the remapbil operator.

Thanks.

I'll go with remapbil,t159grid
