Please provide a clear and concise description of your question or discussion topic.

Dear sir, I want to work on a project related to new particle formation using GEOS-Chem. I'm considering using the TOMAS module to study the nucleation process. I need to incorporate various chemical mechanisms to simulation new particle formation, but I'm unsure how to integrate nucleation mechanisms into the TOMAS module. Do I need to modify the TOMAS code myself?

Thanks for writing and thanks for your patience. Most of us were at the IGC11 meeting earlier in June.

I am tagging @BettyCroft, who is our contact for the TOMAS simulation and perhaps can give you a better perspective than I can.

Thank you for your message and interest in TOMAS. You can go ahead and add additional nucleation mechanisms by modifying the code in tomas_mod.F90 (in the GeosCore directory). Near line 140 of tomas_mod.F90 there are switches for some of the nucleation mechanisms that are currently in use (e.g., bin_nuc and. tern_nuc). Those existing mechanisms can serve as an example for adding further nucleation mechanisms.
