Describe the update

This is the corresponding pull request for https://github.com/geoschem/geos-chem/issues/1288 and should be merged in alongside https://github.com/geoschem/geos-chem/pull/2430.

Yi Wang (@ywang37) updated the soil NOx algorithm in HEMCO to utilize soil temperature as described in Yi Wang et al. (ERL, 2021).

A new option "UseSoilTemperature" has been added to the soil NOx extension. When this option is activated, the soil temperature field from the external model (TSOIL1) will be passed to the SoilTemp function instead of T2M (the temperature at 2 meters). The algorithm in the SoilTemp function will also use the updated calculation from Yi Wang et al. (2021). By default, this function will be turned off until the full record of TSOIL1 fields can be archived for input.

The error messages in the soil NOx extension have also been updated here to provide more detailed information.

Expected changes

This is a zero-difference change with respect to the full-chemistry benchmark because this updated scheme is off by default. To view the expected changes when the algorithm is used, see https://github.com/geoschem/geos-chem/issues/1288#issuecomment-1254031284 in the original Github issue.
