Abstract

The effect of altitude and latitude of sulfate aerosol injection into the stratosphere on climate is studied with Earth system model INMCM. The model includes the general circulation of the atmosphere and oceans as well as a sulfate aerosol component, and is used to determine the most effective injection scenario for reducing changes in temperature and precipitation at a global level and in the Arctic.
