Carbon Cycle And Ecosystems

Project Scientist for OCO-3 and Deputy Project Scientist for OCO-2


Dr. Chatterjee is an expert in carbon cycle science, Earth system models, and utilization of remote-sensing data for tackling large-scale geophysical problems. His research focuses on understanding the interactions between climate variability and the carbon cycle, both globally and in key regions of change, such as the high latitudes and the Tropics. Dr. Chatterjee is part of multiple NASA mission and science Teams. He has also served on multiple synthesis reports, including the 2nd State of the Carbon Cycle Report (SOCCR-2), the 5th National Climate Assessment (NCA5) and has been recently appointed as one of the lead authors for the Third Decadal US Carbon Cycle Science Plan.

Dr. Chatterjee is currently the Project Scientist for the OCO-3 mission and the Deputy Project Scientist for the OCO-2 mission.
