At the height of the COVID-19 pandemic in 2020, UCI Earth system science researchers and their collaborators at UC Riverside drove a mobile lab around Southern California to collect air samples. They found a significant drop in carbon dioxide emissions on the region’s freeways during that time, but the decline soon rebounded as more people took to the roads in the summer of 2021.
