CDO

Hello,
I have an unstructured Netcdf file. I want to convert it to a regular grid and then interpolate with remapbil. I need to calculate the average of different models and have a common grid of 2 ° x2 °, so I must do this.

Any recommendation, I would appreciate it.

This is the description of the file.
