There was a problem hiding this comment.
The new function name is much clearer, thanks!
I should have mentioned this in the first review, but it is generally better to include required variables in the function call, rather than relying on them as global variables. In this case, the function needs start_time, end_time, lat_slice, and lon, but none of them are included in the function call.

This notebook is to decompose variable changes (e.g., temperature, salinity, age tracer) into changes along isopyncals (water mass transformation) and isopycnal heaving. I used
xgcmto do depth-density coordinate transfers and calculate the changes along isopycnals. After that, I transfer this change back to the depth coordinate. The residual term (total change minus change along the isopycnal) is referred to as the change due to isopycnal heaving.
