CDO

hi!

I could interpolate without problem with cdo-2.0.4 and cdo-2.0.5:

cdo -v -P 4 -remapbil,r10x10 -seltimestep,1 `lf` ~/t.nc                                                                      [Tue 2022-04-12|09:04:15]

The only issue is, that you have time-varying coordinate bounds. CDO does not support this feature. so your are limited to interpolations without bounds

regarding the update: Which operating system do you use?

Hi
I'd like to thank you so much for your return.
I use CDO on Ubuntu Windows. As I said, I tried to update CDO by "Sudo apt update" kind of code lines. Yet, it didn't update to CDO 2.0.4 or 2.0.5
So, I'd be so glad if you could explain to me how I can update the CDO on my PC to higher releases/versions.
Lastly, since I am a newbie on these subjects, forgive for such a basic question but I could not get what you mean by "I have time-varying coordinate bounds". I'd be so happy as well if you could describe it to me.
Thanks in advance
Best regards

Hi again,
I forgot to add, sorry for that. Yet, I already installed CDO on Ubuntu in Virtual Environment "Linux". So, I can upgrade my CDO in Linux as well if it is easier to explain

ubuntu comes with a pre-built binary installable with apt, but you wont get the latest release with this. But you can use conda for that - have a look at the Anaconda page

Hi,
Thanks a lot for your return and help.
