The SO2 mass for all significant explosive eruptions in our database (VEI 3+) was converted to sulfate mass in this plot using a typical SO2/sulfate mass ratio (assuming complete conversion of SO2 to sultate aerosol with composition 75 wt% H2SO4 - 25 wt% H2O). To simulate the decay of sulfate aerosol mass with time we assumed a fixed, latitude-dependent e-folding time. |
