During June 2025, Luke Western enhanced the openghg/openghg_inversions repository by implementing NetCDF output compression for HBMCMC results, targeting improved data storage efficiency and I/O performance. He achieved this by integrating ncdf_encoding during the fixedbasisMCMC file saving process, leveraging Python and NetCDF for robust data handling. To ensure consistent test reliability across environments, Luke addressed test instability by explicitly specifying the h5netcdf engine when opening NetCDF files. He also updated project documentation in Markdown to reflect these changes, including details on PARIS NetCDF outputs and RHIME space-saving shuffles, demonstrating thoroughness in both engineering and documentation practices.
