We use isotopes in Environmental and Atmospheric Physics to define how trace gases and atmospheric particles influence cloud characteristics, meteorology and climate. One focus is on tracing how microorganisms at soil/air and water/air interfaces contribute to intense precipitation events. We also work on trace detection of carbon dioxide (CO₂) leaks and factors in soil that affect CO₂ uptake. Three topics we're recently focused on are:
- Aerosol formation
- Trace gas and pollution detection and attribution
Our research is based on a combination of laboratory and field work, as well as data analysis and system modeling.
