On-going Aerosol Working Group Developments

We plan to add these aerosol-related updates to GEOS-Chem in the next few releases:

Update Authors Planned release
Simplified description of uptake of SO2, nitric acid and sulfuric acid on mineral dust Duncan Fairlie, Langley
  • Delivered to GCST
  • Slated for inclusion into v10-02

Future Development Priorities

These are topics which were raised at IGC6 as future updates & development priorities for GEOS-Chem which have not yet been incorporated into the standard code:

Update Authors Priority
Addition of effective wind speed to met fields for consistent resolution dust/sea salt emissions Jeff Pierce (CSU)
David Ridley (MIT)
GCST
medium
Addition of deposition observations to aerosol benchmark Colette Heald (MIT) low
dust simulation expansion (tagged simulation, oxalate, P, Fe chemistry) Matthew Johnson (NC State) low
DMS oxidation scheme updating TBD low
Investigation of how aerosol water is treated in PM comparisons (ISORROPIA vs. hygroscopic growth curves) TBD low
APM capability for nested grid Fangqun Yu (SUNY Albany)
TOMAS capability for nested grid Jeff Pierce (Dalhousie)
Tagged sulfate and nitrate simulation Becky Alexander (U. Washington)
Improved dust simulation in nested-grid model Rokjin Park (Seoul National University)
