Focus
The focus of our research group is to improve understanding of atmospheric processes that underlie regional and continental air quality and the influence that these processes have on climate change, regionally and globally. The goal of our research is to enhance our ability to predict and monitor future changes, leading to improved scientific information in support of decision making.
Measurements
Staff in our group develop and deploy state-of-the-art instruments to measure important atmospheric gas species from ultra-trace levels to the extremely high concentrations found at emission sources. Field studies are critical to our research: Recent field work has included long-term monitoring, short-term limited deployments, and intensive regional campaigns using multiple platforms.
Research platforms
used for field campaigns: NOAA WP-3D aircraft, NOAA R/V Ronald H. Brown, typical ground site.Collaborations
Our research group works in close coordination with other CSD and ESRL groups involved in measurements of atmospheric transport and mixing phenomena, aerosol measurements, laboratory studies, and modeling studies to explore all aspects of the processes in the atmosphere that influence air quality and climate.
