Purpose

The chemical composition of the Earth’s atmosphere is changing due to the influence of human activity. These changes are affecting, and will continue to affect, the quality of life on Earth. Currently, three of the most important issues in atmospheric science are ozone layer recovery, emission and transport of air pollutants and climate change because of their negative effects on human health and ecosystems. Measurements of atmospheric gases are necessary to understand these issues and to monitor atmospheric gases as part of international treaties and protocols. To address these issues, my research group makes measurements from the ground to study the chemical makeup of the Earth's atmosphere and how it is changing with time. To further this research program, we will undertake the following projects over the next five years.
