    • Brief Bio

    Dr. Chatterjee is a Scientist and the GESTAR Group Lead at the Global Modeling and Assimilation Office (GMAO), primarily working on carbon cycle dynamics and carbon-climate feedback problems. Prior to joining GMAO, he was a NOAA Climate and Global Change Postdoctoral Fellow (2013-2014) at the National Center for Atmospheric Research in Boulder, Colorado. He received his PhD ('12) from the University of Michigan, Ann Arbor working with Anna Michalak and Richard Rood. During this time, he also spent a couple of years as a Visiting Investigator at the Carnegie Department of Global Ecology (Stanford University). 

    Research Interests

    Constraining Carbon-Climate Feedback using Contemporary Observations

    Dr. Chatterjee's research interests include global carbon cycle dynamics, carbon-climate feedbacks, and coupled biosphere-atmosphere dynamics. His research aims to further the understanding of global carbon cycle processes and the ability to predict future co-evolution of atmospheric CO2 concentrations and climate. 

    Current Projects

    Carbon-climate dynamics

    Understanding the interactions between climate variability and the carbon cycle, with specific focus on the processes that maintain and alter the composition of the atmosphere and the climate
     

    Coupling between the carbon and the water cycle

    Understanding the linkages between carbon and the hydrological cycle over "hotspots" (e.g., high-latitudes, Tropics) by exploiting the synergy between NASA's remote-sensing missions (OCO-2 and SMAP) and field campaigns (ABoVE)
     

    Next-gen remote sensing missions to observe the carbon cycle

    Developing and implementing Observing System Simulation Experiments (OSSE) efforts to define NASA's next-generation of missions for observing greenhouse gases from space
