Description

Try compressing that gridded forcing netcdf as we save it and see how much it affects the file size and the forcing processing speed. It's currently completely uncompressed which makes it unreasonably large and makes it harder to share ngen-run folders without deleting it.

Contributor guide

Research direction
Investigate compression settings for netCDF files using the netCDF4 library, specifically zlib or szip compression, and evaluate the trade off between file size reduction and processing speed.
