Mari Tye (Jul 15 2022 at 17:49): Mari Tye (Jul 15 2022 at 17:49):I have a netcdf file from the UK ESM with 360 day calendar origin 2015-01-01. The netcdf will only open in xarray if I use "decode_cf = False".... so then I lose all of the time data. What argument(s) should I use to open the file and specify calendar type and origin?
Deepak Cherian (Jul 15 2022 at 17:50):What's the error it raises?
Mari Tye (Jul 15 2022 at 17:59):If I open without the "decode_cf = False" argument I get
AttributeError: 'CFTimeIndex' object has no attribute '_cache'
Opening with the argument means I get time as a series of days since origin. Oh I forgot to mention time is "t" not "time":
