Thanks! I tracked this down to the difference between reading the file remotely, or downloading first and accessing a local copy on v0.20.2 (the latter is what I used to produce my figures). Can you reproduce? remote = xr.open_dataset( "http://kage.ldeo.columbia.edu:81/SOURCES/.LOCAL/.sst.mon.mean.nc/.sst/dods" ).sst.sel(lat=20, lon=280, method="nearest") local = xr.open_dataset("~/Downloads/data.cdf").sst.sel(lat=20, lon=280, method="nearest")

(remote.groupby("time.month") - remote.groupby("time.month").mean()).plot()

(local.groupby("time.month") - local.groupby("time.month").mean()).plot()
