Dear WRF-Chem officials
I want to use WRF-Chem to simulate DMS and its impact on air quality. Although the user manuals do include some information about DMS, I still have many questions.
As many articles mentioned, the sources of DMS include 3 main aspects: oceanic, anthropogenic and biogenic. Both anthropogenic and biogenic DMS emissions can be found in the official 'emission guide'. So my question is how to contain oceanic emission into WRF-Chem.
I notice there is a chemistry namelist option named 'dmsemis_opt', and the related explanation says 'need to provide dms reference field (currently only working for GOCART options)'. Suppose I have a netcdf file contains DMS sea surface concentration(or DMS flux), then how should I use it and make it a wrfchem input file. I think each kind of emission input correspond to an 'auxinput channel', for example, auxinput_5 -> Anthropogenic emissions and auxinput_6 -> Biogenic emissions (BEIS, MEGAN). But I can't see a channel correspond to oceanic emission.
What's more, is GOCART the only alternative aerosol scheme to simulate DMS as the explanation says? In the registry.chem file, I found some other options include dms,dmsp, like CBM-Z. So if it's possible to use these other options to simulate DMS? And If so, the 'dmsemis_opt' should set to 0 or 1?
I hope my description is detailed and comprehensible and any guidance is appreciated.
