Dynamics of Multiscale Atmospheric Chemistry
Focus: To develop a deeper understanding of the underlying dynamics, physics and chemistry involved in transport, dispersion and transformation of atmospheric pollutants, particulates and chemical constituents.
Atmospheric chemical and particulate transport, dispersion and transformation depend on accurate specification of the dynamics and physics across a wide range of scales, from microscale to mesoscale.
Important processes include:
- Surface-atmosphere interactions;
- Boundary layer turbulence transport and dynamics;
- Exchange between the boundary layer and free troposphere; and,
- Boundary layer venting via convective transport, rainout, and chemistry.
Our research focuses on the following topics:
- tracer transport in complex terrain
- tracer transport in and above forest canopies
- wildland fires and their impact on air quality
- tracer transport in boundary layer with shallow cumulus clouds
- fumigation of passive tracers
- mesoscale transport of tracers downwind of megacities
- transport and transformation of tracers in deep convection
- modification of clouds by anthropogenic aerosols
