Cropping NetCDF by NCO

Question

I would like to crop my NetCDF file for a specific location using NCO. However, I am quite lost in the documentation. So far, I've tried this:

ncks -v Precipitation_Flux -d lon,-18.751,-7.684314, -d lat,-40.9972,33.696913 C3S_concat.nc C3S_concat_cropped.nc

With error:

ncks: ERROR parsing hyperslab specification for dimension lon,-18.751,-7.684314,
Stride must be specified (and be a positive integer)

Deleting float and negative values didn't help me. And I am not understanding what is the Stride.

Okey I see that NCO topics are quite intensively discussed in StackOverflow. Should I put it there? — Luckasino, Commented Nov 25, 2020 at 9:46

The error you received was due to the extra comma in the -d lon option. Try this:

ncks -v Precipitation_Flux -d lon,-18.751,-7.684314 -d lat,-40.9972,33.696913 C3S_concat.nc C3S_concat_cropped.nc
