Hi @peterdudfield
I hope this message finds you well

As I was reviewing the paper, I came across something I wanted to clarify regarding the 12 x 12 pixel slicing for NWP. When selecting one region of interest (ROI) as the central position, moving 6 pixels up and 6 pixels down would actually result in a 13 x 13 pixel area, not 12 x 12 pixels. Could you please explain how the 12 x 12 pixel dimension was determined in this context?

Hey

We then use this idx to select the data like this

xr_data = xr_data.isel({xr_x_dim: slice(left_idx, right_idx)})

I think this means that ;eft_idx is include, but right_idx is not. This is similar to range(0,12), not include 12.

Hope this helps
