| Zusammenfassung |
| The chemistry-climate model EMAC interactively simulates stratospheric and tropospheric
chemistry, aerosols and dynamics, accounting for trace gas and particle emissions
including volcanic SO2 injections derived from MIPAS satellite data and other
data sources. Aerosols are represented using a seven-mode submodel from which
optical properties are calculated based on Mie theory, feeding back into radiative
heating rates and atmospheric dynamics. We demonstrate that medium and even
smaller volcanic eruptions contribute significantly to the radiative forcing of climate
by perturbing the background stratospheric aerosol in the period 2003 to 2011. |
