Notes

[aethr]

After a full run of the prior, the output file has these global attributes (from ncdump):

// global attributes:
		:DX = 10000.f ;
		:DY = 10000.f ;
		:TRUELAT1 = -15.f ;
		:TRUELAT2 = -40.f ;
		:MOAD_CEN_LAT = -27.644f ;
		:STAND_LON = 133.302f ;
		:XCELL = 10000. ;
		:YCELL = 10000. ;
		:XCENT = 133.302001953125 ;
		:YCENT = -27.5 ;
		:XORIG = -2270000. ;
		:YORIG = -2165629.25 ;
                // attributes below are added in this PR
		:title = "Open Methane Prior Estimate" ;
		:comment = "Gridded prior emissions estimate for methane across Australia" ;
		:history = "2024-11-25 22:09:22.573050+00:00: scripts/omPrior.py --start-date 2022-07-22 --end-date 2022-07-22" ;
		:openmethane_prior_version = "v0.2.0" ;

The version in openmethane_prior_version comes from the OPENMETHANE_PRIOR_VERSION env var in docker, or from pyproject.toml if run locally. The OPENMETHANE_PRIOR_VERSION value is baked into the container at build time using --build-arg VERSION, and if run locally it will be set to development.
