The Atmospheric Chemistry and Dynamics Branch (Code SGG) conducts scientific
research on important environmental issues in stratospheric chemistry and ozone
depletion, stratospheric-troposphere exchange, pertubations in the chemical
composition of the troposphere, and climatic changes from clouds, aerosols, and
greenhouse gases. The SGG effort includes: a) development and deployment
of sensitive, state of art instruments on airborne platforms (including aircraft,
balloons, and uninhabited aerial vehicles UAV's, b) modeling of chemistry, dynamics
and radiative transfer processes to understand and elucidate controlling mechanisms,
c) laboratory experiments which advance the understanding of detailed dynamic
chemical interactions in the stratosphere, and d) advocacy, planning and execution
of selected field projects for the Office of Earth Science.

SGG is organized into four groups: 1) Chemistry 2) Dynamics 3) Sunphotometer-Satellite
4) Project management.
