1 year ago @gkb999 - I don't think the anomaly should necessarily be zero. If I have 6 temperature values: [255, 260, 265, 265, 260, 255] and I use the full period (all values) then the mean is 260. I subtract the mean from each value to get the departures: [-5, 0, 5, 5, 0, -5]. So there are zero values, but the anomalies are not always zero.
Greetings From the page : https://xcdat.readthedocs.io/en/stable/generated/xarray.Dataset.temporal.departures.html Departures calculated say: if no Reference_period is provided, the climatological reference period will be the full period covered by the dataset. In that case, the anomaly should be zero, right? I used that option, where I left xcdat to use the default way to calculate anomalies and I don't get zero yet. Any explanation would be appreciated
