Though I am beginner, would like to know how to add time dimension in pre-process mode to open all the files at one calls.

Hello @HARSHBARDHANK94

You should try something like:

def preprocess(ds):
	# is time in ds.attrs ; if it's in the filename look at ds.encoding['source']
	ds["time"] = ...
	return ds


xr.open_mfdataset(..., concat_dim="time", preprocess=preprocess)
