Exploration of the Mechanistic Relationship Between Improved Regional North American Inverse Carbon Fluxes and Climate Variability/Trends

Funded by the National Science Foundation

This project will use improved time-dependent net carbon exchange results from the TransCom intercomparison to advance quantitative understanding of the feedbacks between net carbon exchange and climate variability /change for the U.S. The project will improve upon recent inverse work through expansion and extension of observations, a state-of- the-art fossil fuel CO2 flux product, and sensitivity to inter-annually varying transport. The regional carbon-climate relationships will be further explored mechanistically through process datasets (NDVI, fire, drought) and terrestrial biosphere model results.
