We are delighted that recent research assistant Andrew Hallward-Driemeier has joined the graduate program in the Columbia University Dept. of Earth and Environmental Sciences and will continue in the group as a graduate student. With his experience running the long-term CO2 and CH4 observation sites around NYC, Andrew will be investigating some of the interesting processes we have seen in the urban area, including the impacts of incomplete combustion.
