xpbch is a simple utility for reading the proprietary binary punch format (bpch) outputs used in versions of GEOS-Chem earlier than v11-02. The utility allows a user to load this data into an xarray- and dask-powered workflow without necessarily pre-processing the data using GAMAP or IDL. This opens the door to out-of-core and parallel processing of GEOS-Chem output.

Recent Updates

v0.3.3 (March 18, 2018)

  • Clean-up for xarray v0.10.2 compatibility
  • Tweak to more reliably infer and unpack 3D field shape (from Jenny Fisher)
