I would like to select Indian Ocean 40E-100E, 20S-20N idir = '/g/data/p66/mrd599/cq880/history/ocn/' fname = idir + 'ocean-2d-surface_pot_temp-1-monthly-mean-ym_03*.nc' ds = xr.open_mfdataset(fname, combine='by_coords') ds.surface_pot_temp lat_range = (-20, 20) lon_range = (40, 100) ds2 = ds.assig…

[image] ars599: ds.assign_coords({“xt_ocean”: (ds[“xt_ocean”] + 360) % 360}) This just resets the coordinate values to be in the range 0-360 deg, but the Indian Ocean is still split across the edge of the array. There are a number of ways of dealing with slicing periodic coordinates across ar…
