Xarray find lat/lon coordinates for maximum/minimum values for each timestep
Question:
As the title says, supposing I have a ds with coords: [time lat lon], how can I obtain for each timestep in time the pair of ['lat','lon'] in which the maximum(or minimum) value for a given variable is located.
Answers:
Use xr.Dataset.idxmax to find the index label of the maximum along a dimension (one at a time). Same for xr.Dataset.idxmin.
max_lons = ds.max(dim="lat").idxmax(dim="lon")
max_lats = ds.max(dim="lon").idxmax(dim="lat")
The results will be datasets, with each variable giving the lon or lat coresponding to the maximum in each time step for that variable.
