-:I don't think my fix for this issue is ready for prime time. I get chimneys of essentially unscavenged SO2 extending into the UTLS during Asian monsoon, leading to too much sulfate aloft. I think replacing the instantaneous titration of H2O2 in the standard code with the correct oxidation of SO2 by H2O2 (and O3?) is necessary.
