To facilitate provenance within E3SM experiments and model intercomparisons, the following standards should be followed in all files output by E3SM components.
History global attributes
History files from E3SM components should all have these global attributes. Examples are from EAM and should be adjusted as appropriate.
Anything labeled as “from coupler” can get its value from the infodata block in the coupler with a call to seq_infodata_GetData
