Within the Solomon group at MIT, we focus on interactions between chemistry and climate, at both poles of the Earth as well as the tropics. A selection of current projects includes:
• Probing heterogeneous chemistry in the tropical stratosphere.
• Evaluating and understanding the healing of the Antarctic ozone hole.
• Quantifying emissions of chlorofluorocarbons, hydrochlorofluorocarbons and hydrofluorocarbons, including those from “banks” in applications such as refrigeration, air conditioning, and insulation foam.
• Developing methods to include gravity wave impacts on temperature-dependent atmospheric chemical reactions.
• Determining whether the width of the Earth’s tropics are changing, and why.
• Ocean-atmosphere interactions.

• Influences of volcanoes on the chemistry, climate, and radiative properties of the Earth’s atmosphere.
• Evaluating the spatial variability of the onset, duration, and severity of anthropogenic climate change.
• Improving the understanding of Antarctic ozone changes using satellite and ground-based data.
• Exploring the behavior of the ice-age stratosphere.
• Documenting the emergences of significant changes in climate in the stratosphere and troposphere, and comparing these for models and measurements.
