OpenMethane - v1.0.0

openmethane-prior v1.0.0 (2025-08-22)

⚠️ Breaking Changes

• Output changes:

  • OCH4_{SECTOR} output variables have been renamed to ch4_sector_{name}
  • OCH4_{SECTOR} variables which previously produced a single time-step are
    now expanded to include a time step for each day in the period
  • Output file coordinates have been normalised to ('time', 'vertical', 'y', 'x')
    to follow CF Conventions

  (#70)

• Default output filename has been changed from out-om-domain-info.nc to
  prior_emissions.nc (#75)

• Official Open Methane domains will now follow a simple incremental versioning
  scheme (v1, v2, etc.) rather than semver (v1.0.0) (#78)

• Major updates to the domain info file will require re-creating existing domain definitions (#106)

🗑️ Deprecations

• Output deprecations:

  • OCH4_TOTAL output variable is deprecated in favour of ch4_total
  • LANDMASK output variable is deprecated in favour of land_mask
  • These deprecated outputs will be removed in the next release

  (#70)

🎉 Improvements

• Test coverage has been improved and several low-value, high-cost tests have
  been disabled until they can be improved (#70)
• Output now follows more CF Conventions including projection details, bounds,
  and standard attributes for all data layers (#70)
• Improvements to test maintainability and consistency (#74)
• Add internal Grid utility class to provide common grid and coordinate logic (#81)
• Add grid "slug" or short name to output file (#82)
• Add "cell_name" to output file with a short unique name for each grid cell (#83)
• Fix Grid performance by removing @property usage (#86)
• Add Grid.lonlat_to_cell_index method which works efficiently on lists (#86)
• Adopt standard reprojection approach using Grid class throughout the project (#87)
• Replace print statements with configurable logger (#100)
• add inventory mask (#103)
• use inventory mask on relevant sectors (#105)
• Remove XORIG and YORIG from domain format, use x_bounds and y_bounds instead (#112)
• Add create_subset_domain script to make it easier to create a domain inside aust10km (#113)
• Allow prior domains that dont share projection with the inventory (#115)

🐛 Bug Fixes

• Fix reprojection in agriculture, LULUCF and waste layers (#90)
• Add grid_mapping attribute to land_mask output variable (#92)
• Disable _FillValue in output meta variables like coords and bounds (#92)
• Added the grid projection offsets in XORIG/YORIG to the Grid projection (#106)
• fixing national inventory normalisation (#114)
