    SEAC4RS - Goals:

    1. To determine how pollutant emissions are redistributed via deep convection throughout the troposphere.

    2. To determine the evolution of gases and aerosols in deep convective outflow and the implications for UT/LS chemistry.

    3. To identify the influences and feedbacks of aerosol particles from anthropogenic pollution and biomass burning on meteorology and climate through changes in the atmospheric heat budget (i.e., semi-direct effect) or through microphysical changes in clouds (i.e., indirect effects).

    4. To serve as a calibration/validation test bed for future satellite instruments and missions.

    Focused studies to address SEAC4RS goals: To achieve the goals listed above, we will conduct a series of 4 focused studies. Some science issues overlap with several focused studies and will be included within the focused studies. However, these overlapping issues are discussed separately here.   >> more
