The SO 2 mass for all significant explosive eruptions in our database (VEI 3+) was converted to sulfate mass in this plot using a typical SO 2 /sulfate mass ratio (assuming complete conversion of SO 2 to sultate aerosol with composition 75 wt% H 2 SO 4 - 25 wt% H 2 O). To simulate the decay of sulfate aerosol mass with time we assumed a fixed, latitude-dependent e-folding time.

Sulfur Dioxide | Wisconsin Department of Health Services
Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid. Sulfuric acid is a major component of acid ...
