Sulfate aerosols from volcanoes appear to play an important natural role in ozone depletion. Sulfur dioxide (SO2) reacts with water to form sulfuric acid (H2SO4) in an aerosol form. ... chlorine from the plume reaches the stratosphere. The general conclusion is that volcanically-produced sulfate aerosols have a destructive effect on ozone, but that volcanically-produced chlorine is of ...

Climatology
Aerosols block some sunlight and thus cause surface cooling. Sulfate aerosols are highly reflective which leads to cooling. Aerosols can have a strong effect on ... of sulfuric acid. These small drops produce a haze, also called an aerosol, which has a high albedo. The aerosol reflects sunlight, resulting in cooling. Sulfur dioxide also produces acid rain. Astronomy ...

The Regional Impacts of Climate Change
GHGs and aerosols. Because the anthropogenically induced sulfate aerosol burden has large spatial and temporal variations in the atmosphere, its regional- ... The implications of enhanced aerosol loading on tropospheric clouds, which could strongly modulate the monsoon climate, still are not clear. Because anthropogenic sulfate aerosol loadings are projected to ...
