Project Grant 2242034

This $337,455 Project Grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) will fund research to constrain the continental-scale terrestrial carbon cycle using data from the National Ecological Observatory Network (NEON). The awardee, Cornell University, will develop refined continental-scale carbon profiles and flux products through a novel approach integrating NEON observations, satellite data, data-driven methods, and data-model integration techniques. Specifically, the researchers will utilize NEON data to produce hourly, gridded gross primary production estimates with uncertainties. They will also develop complementary gross primary production products using NEON data and solar-induced chlorophyll fluorescence from satellites. The investigators will apply multiple NEON datasets and production models to quantify the U.S. land carbon sink and evaluate NEON data's ability to reduce model uncertainties and constrain parameterization. Insights on continental carbon dynamics and regulatory mechanisms are expected.
