| Zusammenfassung |
| The framework of ICTP-RegCM is coupled with full gas-phase chemistry. The main object of this work is to study the impact of ozone on regional climate change. Our gas-phase mechanism is based on (Ito et al. 2007 and Sillman et al. 2007.). This gas phase mechanism has 532 reactions, and 175 compounds, 21 compounds are transported, including NOx,O3, CO, SO2, H2SO4, CO, HCHO, DMS, H2O2, HNO3, PAN, ISOP, CH4, …
Full gas-dry deposition module is coupled with RegCM to compute the interactive gases dry deposition.
Different gas phase mechanisms have been tested as box model and validated using gas-chamber data. We use such comparison to select the fastest mechanism for climate-chemistry simulation. We select (Ito-Sillman) mechanism to be coupled with RegCM because it is comprehensive and fast. |
