Aerosol Discussion Points
for the 12th Annual CCSM Workshop
- What are the candidate treatments of oxidant chemistry and aerosols?
- Should more than one be supported on the trunk? For how long?
Discrimination of Schemes
- Do aerosols have to be simulated online to simulate direct and indirect effects?
- Which oxidant chemistry needs to be treated to simulate direct and indirect effects?
- How important is ammonia nitrate in the past/present/future?
- What are the trade-offs between run time and realism in different representations of oxidant chemistry and aerosol physics?
- Which aerosol sources are missing?
- Can aerosol
sources be treated independently of the representation of aerosol
mixing state and size distribution? What simplifications in the
representation of the aerosol mixing state and size distribution are
Dust and Seasalt
- How should these be binned to interact with the microphysics
What interfaces can be introduced that will facilitate the application of aerosol modules to the CCSM to treat:
- Dependence of emissions on surface properties and processes
- Dependence of dry deposition on surface properties
- Gas-to-particle production of aerosol in clear air
- Activation, aqueous-phase production and wet scavenging of aerosol (cloud-aerosol interactions)
- Optical properties of aerosol
- Which aerosol measurements would be most useful for validation?
- Should the aerosol scheme(s) be represented in Aerocom?.
