Changes in removal pathway has twice impact of key source on ozone pollution levels

Better understanding of this ozone sink is essential for improved modeling and prediction of air pollution, ecosystem health, and climate.

COM Program partnership with NCEI's Applied Research Center puts instrumental record into long-term context 31 March 2020

COM Program partnership with NCEI's Applied Research Center puts instrumental record into long-term context

The partnership has resulted in a number of high quality paleo datasets, without which significant advancements over the last 5 years in understanding societally-relevant risks such as drought and temperature changes in a long-term context would not have been possible.
