CDO

Hi Ingrid,

if you had googled the question, you would have got the answer immediately.

cdo -setgridtype,regular infile outfile

Hi Karin, thanks for your answer.

I have tried some solutions that I found on the internet, but still without sucess.

I tried your code and cdo says "There is no reduced grid". I need to convert a T126 Gaussina Grid (lat from 0 to 360) to the traditional LatLon (lat from -180 to 180).

The solution that worked was "cdo remapbil,grid_example.nc if.nc of.nc". The problem now is that my example file has a high resolution and the file I'm trying to convert changed from 500 MB to 31 GB.
Probably I need a example file with a resolution more similar to T126, or I need to change the method.

Can you upload the data file? One timestep is enough.

Of course! Its attached.

I also tried "cdo remapbil,t126 if.nc of.nc" and CDO warned "grid type spectral not suported", although when I tried "sp2gp" operator it says "No spectral data found".

What is example_file.nc?

Remap the gaussian grid to lonlat grid:

cdo -sellonlatbox,-180,180,-90,90 -remapbil,r384x192 gaussian.nc outfile_T126_lonlat.nc

Example_file.nc is in the type of grid I want gaussian.nc to be converted.

I need to compare their values... Starting from an specific point, same coordinate in both files.

Then the above information was misleading.

cdo -remapbil,example_file.nc gaussian.nc outfile_grid_of_example_file.nc

Thanks Karin!

Problem solved
