What's new in this version
Updates that will not affect fullchem benchmark simulations
| Feature | Contributor(s) | Model scope | Notes and references |
|---|---|---|---|
| Fix incorrect indexing for TOMAS OCIL/OCOB and ECIL/ECOB species | Nicholas Balasus (Harvard) | Aerosol microphysics | |
| Prevent TOMAS debug print statements from executing unless verbose output is requested | Nicholas Balasus (Harvard) | Aerosol microphysics | |
| Specify AOD wavelength (in nm) in the geoschem_config.yml file for the aerosol-only simulation so that dust AOD diagnostics will work properly | Bob Yantosca (Harvard) | Aerosol-only simulation | |
| Add RxnRate, RxnConst and KppDiags diagnostics to the carbon and Hg simulations | Bob Yantosca (Harvard) | Diagnostics | |
| Add script to generate lists of species per simulation for ReadTheDocs documentation | Bob Yantosca (Harvard) | Diagnostics | |
| Edit GCHP emission diagnostic entries in HEMCO_Config.rc and HISTORY.rc files for consistency | Bob Yantosca (Harvard) | GCHP | |
