GEOS-Chem v11-02-final will also carry the designation GEOS-Chem 12.0.0. We are migrating to a purely numeric versioning system in order to adhere more closely to software development best practices. For a complete description of the new versioning system, please see our GEOS-Chem version numbering system wiki page.
The GEOS-Chem species database provides a central location for storing the physical properties of GEOS-Chem species, including names, indices, molecular weights, and Henry's law constants. It also stores logical flags that denote whether each species is advected, is dry deposited, or is wet scavenged.
all species are now just stored in the State_Chm%Species array.
Please see the following resources for detailed information about the species used in GEOS-Chem simulations as well as the data structures in which they are stored:
