Her work combines aircr aft, tall tower and eddy flux measurements, with process based models to understand the atmospheric budget of a range of trace gases, with a focus on carbon in the Arctic. She is co-lead of the NASA Arctic and Boreal Vulnerability Experiment (ABoVE) Carbon Dynamics Working Group and a member of the Science Leadership Group of the North American Carbon Project (NACP). As part of NASA’s Atmospheric Tomography Mission (ATom), she recently made airborne measurements of CO2, CH4, N2O and CO on the NASA DC8 on flights in the remote atmosphere above the Pacific and Atlantic oceans 2016-2018.
