K085: Drivers of Global Change in the Antarctic: Atmospheric Remote-sensing

Dan Smale

The Antarctic atmosphere is an important and unique part of the global climate system. It provides a unique opportunity for us to measure global trends in atmospheric trace gases at sites isolated from anthropogenic sources.

The goal of this research is to improve understanding of how the Antarctic atmospheric chemistry drives and responds to global atmospheric change. Research topics include: ozone depletion chemistry, greenhouse gas measurements, sea-ice/atmosphere trace gas interactions and the pole-ward transport of atmospheric constituents.

To this end, we measure the atmospheric composition throughout the year using ground-based remote sensing instruments and surface in-situ air samples, located at Scott Base and Arrival Heights.
