HAO Colloquium

back to top

    Speaker: Mike Mills, LASP, University of Colorado

    Time: December 20, 2006, 1:30 pm, CG1-2126

    Title: The mesospheric sulfate aerosol layer

    Abstract:

    We investigate the heretofore-unstudied role of volcanic and non-
    volcanic sulfur aerosols and gases in the mesosphere. Two- dimensional
    microphysical calculations show that sulfur may be an important source
    of particles below the cold summer mesopause. Observed increases in
    SO2 with altitude in the upper stratosphere had previously suggested
    ultraviolet destruction of H2SO4, discounting its survival in the
    mesosphere.
    For more of the abstract, please visit our website...

    For more information, contact Amy Knack at ext. 2174, knack@ucar.edu,
    or see the Web page at HAO Colloquia.
