Project Summary:

 

UTLS

Work with Laura Pan on the UTLS project performing chemical transport analysis in the tropopause region using available model, aircraft, and satellite data sources. He has also working on the following projects with the external & internal collaborators listed:

  • Modeling Cloud-Aerosol interactions with detailed particle and hydrometer spectra: W.W Wobrock and A.I Flossmann, Université Blaise Pascal, Clermont-Ferrand, France

  • Modeling winter time snow clouds over the Japan Sea: Masatak Murakami  Meteorological Research Institute, Ibaraki JAPAN

  • Modeling aerosol effects on precipitation formation:- Roelof Bruintjes, RAL, NCAR.

  • The development of an improved two-moment microphysical scheme with improved
    aerosol physics: Richard Farley , Institute of Atmospheric Sciences, South Dakota School of Mines
    and Technology, Rapid City, South Dakota
