| Abstract: |
This project’s area of emphasis is in theoretical/process modeling. The focus in this project is to address the need to improve the theoretical representation of organic aerosol processes and to enhance the incorporation of aerosol process information into large scale atmospheric models. Our project aims are
(i) to develop a comprehensive and flexible thermodynamic treatment of equilibrium gas-particle partitioning, water uptake, size and phase state in atmospheric aerosol systems containing both organic and inorganic compounds;
(ii) to use this model to derive simplified representations of SOA (Secondary Organic Aerosol) formation and properties suitable for large scale atmospheric models.
We achieve these aims, and incorporate the results into atmospheric models for use within the Atmospheric Science Program, through a wide-ranging alliance with DOE scientists and university colleagues applying for funding in this program. The thermodynamic treatment is based upon an extension of the Aerosol Inorganics Model (AIM), which is a well established gas/aerosol partitioning code used for model development and interpretation of field and laboratory observations. The project impact is maximized by making the models available for public, interactive use on the world wide web. |
