In general, aerosols influence the climate directly by scattering and absorbing the solar radiation and indirectly by acting as cloud condensation nuclei and ice nuclei, which modify the radiative properties of clouds. To estimate the effects of anthropogenic aerosols on the climate in future, we used earth system model simulations. The emission of anthropogenic aerosols can be decreased by controlling...
Solar geoengineering (or Solar Radiation Management, SRM) refers to any intentional, large-scale manipulation of the Earth's incoming solar radiation to offset some of the effects of anthropogenic greenhouse gases, reducing the associated risks from climate changes. Examples of such methods are injecting aerosols into the stratosphere or increasing marine cloud reflectivity, both of which would reflect...
The climate effects of black carbon (BC) aerosol due to anthropogenic and biomass burning emission over East Asia in spring time from year 2000 to 2004 have been simulated. the net downward radiative flux at top of atmosphere (TOA) in both clear and all sky are increased by BC, but it is decreased at the surface (SRF). The changes of radiation in the Si Chuan basin can reach 4W/m2 at TOA, and -5.5W/m...
The Regional Climate Model version 3 (RegCM3) is used to investigate the effect of organic carbon (OC) and sulfate aerosol on radiation forcing and regional climate in East Asia. The simulation results show that OC aerosol produces a negative radiation forcing at the whole atmosphere column and at the surface in this region. The negative radiation forcing becomes less significant from south to north...
