Remove data from 4D .netcdf files through a for loop

Hi,

I am wondering if anyone could help me to find a practical, and fast, solution to remove "layers" from .netcdf files that have 4 dimensions. Specifically, my files have size (X, Y, Z, Time):

The original size is: 360x180x33x1980

and my goals is to reduce the 3rd dimension (Z), leaving me a new file with size: 360x180x10x1980

Here I would like to keep the first 10 (Z) layers and remove layers 11 to 33. Then save the file with the same name.

I have hundreds of files where I need to do the same removal, so ideally I would like to find a solution where I can use the script through a loop.

Thank you for your help in advance!

You can do this using MATLAB's built-in ncread and ncwrite functions.

You can read more about it from the links below:
