oh I get it now. Thanks. Indeed it works now when chunking lat and lon from the start.

It has to compute the quantile first before overwriting ds. Your error is at that computation stage.

ds.chunk({'time': -1})

I suspect this is making your entire dataset one big chunk. I would chunk along lat and lon in open_mfdataset first.

But if I am doing ds.quantile(quantiles, dim='time') and assigning it again to ds, wouldn't that erase the big dataset from memory? (sorry for the ignorance). Thanks
