The Atmospheric Chemistry and Dynamics Laboratory advances understanding of changes in the Earth’s radiation balance, air quality, and the ozone layer that result from changes in atmospheric composition. Using a combination of satellite data, atmospheric models, and in situ observations, the Laboratory strives to understand:
• the factors that control stratospheric ozone and trace gases that influence ozone,
• the natural processes and human activity that impact the composition of Earth's troposphere, and
• the impact of climate change on future concentrations of stratospheric ozone and tropospheric gases.
