What new functionality do you need?

UFSWM lossy compression will be changed to use netcdf quantization routine instead of builtin routines currently used in the model.

The UFSWM PR that implements this change is ufs-community/ufs-weather-model#1990

What are the requirements for the new functionality?

This requires the change in model_configure file. The two new options will be added:

  • quantize_mode: character string. Possible values 'quantize_bitgroom', 'quantize_granularbr', 'quantize_bitround'
  • quantize_nsd: integer, number of significant digits.

See documentation here.

Current option that controls the quantization nbits: will be removed.

Acceptance Criteria

model_configure file must be updated to use new configuration options.
