A CSL and GML team, tropospheric ozone

Kai-Lan Chang, Owen Cooper, and Audrey Gaudel (NOAA Chemical Sciences Laboratory) and Irina Petropavlovskikh (NOAA Global Monitoring Laboratory) initiated the Tropospheric Ozone Assessment Report (TOAR), a research activity in the framework of the International Global Atmospheric Chemistry (IGAC) project. TOAR a) produced the first tropospheric ozone assessment report based on the peer-reviewed literature and new analyses, and b) generated easily accessible data on ozone exposure and dose metrics at hundreds of measurement sites around the world, helping with research on the global-scale impact of ozone on climate, human health and crop/ecosystem productivity. The team’s work has resulted in many high-impact publications and has greatly improved our knowledge of tropospheric ozone trends as it relates to climate change and health impacts.
