Get specific timesteps defined by a multiplier

Added by Alonso Arriagada over 4 years ago

Hi all!

I need to select specific values from a variable considering timesteps defined by a multiplier, for example, get only the multiples of 4 of the entire list of time steps of the original NC file.

The NC file has 54056 timesteps.

If anyone could help, I will be very grateful!

Thank you!
Best!
Alonso.

Hi Alonso!
I think you can use the splitsel operator. It will generate lots of files, but only in an intermediate step.

cdo splitsel,1,0,3 -seltimestep,1/200 out_1.nc outT

could be first test for selecting only the real year values.

you can concatenate the files with

cdo cat outT0000* _outT.nc

this should give you a proper start, I hope

cheers
