Regional & Process Modeling

Group Lead: Mary Barth

Scientific Objectives

RPM contributes to ACOM's primary research goals through the identification of key atmospheric chemical transformations and physical processes affecting chemical constituents.

Topics include: 1) global, regional, and urban air quality,  2) the chemistry of the climate system, and 3) radiative properties and forcing of anthropogenic pollutants, . 

Research Topics

  • Field campaign data analysis (MIRAGE, DC3, SAS, FRAPPE)
  • Explicit and 3D modeling of secondary organic aerosol (SOA) constituents
  • Cloud-aerosol interactions
    • Learn more about WRF-Chem modeling of cloud-aerosol interactions in India
  • Future Air Quality in South Asia using WRF-Chem (PIs: Rajesh Kumar, Mary Barth)
  • Effects of UV radiation on photochemistry and the biosphere
  • Changing Emissions on Regional and Global Scales
    • Learn more about development and evaluation of fire emissions
    • Learn more about emissions and impacts in Africa
    • Learn more about WRF-chem studies to evaluate the impacts of residential emissions in China
