Variable "Time" is not "unlimited" when written to file via DropDigits #22

Closed olafurrognvaldsson closed 4 years ago

DropDigits does not label the time-variable as unlimited when writing it to a new file

IIRC this allows the files to be compressed more aggressively and the idea was that the dataset was already compete. What is the problem being caused by this?

olafurrognvaldsson commented 4 years ago

The files can not be read by the LVC code. I think this Stackoverflow issue is relevant - https://stackoverflow.com/questions/20340977/using-mfdataset-to-combine-netcdf-files-in-python

@kstanislawska could you give a more accurate description?

logi commented 4 years ago

The MFDataset can only read a collection of files if their time dimension is unlimited. And I suppose it is out of the question to combine them into a single file.

yes, a typical size for a one-year batch is ~350GB
