| 158078410 | MDU6SXNzdWUxNTgwNzg0MTA= | 865 | How to reduce the output size with to_netcdf? | 19703996 | closed | 0 | 6 | 2016-06-02T07:45:28Z | 2022-08-24T14:42:48Z | 2022-08-19T01:32:04Z | NONE | Hello, The options of the ds.to_netcdf method allow several netcdf modes and a control of several options (missing values, format...). Our current options are as follows: ds.to_netcdf(filenam, 'w', 'NETCDF4', 'netcdf4', encoding={ vkey2:{'dtype': float32,'_FillValue':0}}) Whereas the input size is 6 GiB / variable, the output size reaches 23 GiB / variable. What is the best strategy in the options to reduce the netcdf output size, other than changing the format (in my exercice we have float32)? In particular, is there some interest in modifying the deprecated "missing_values" attribute? Thank you in advance, |
