CARBON DIOXIDE (CO2) IS THE SINGLE MOST IMPORTANT GREENHOUSE GAS IN THE EARTH S CLIMATE SYSTEM. UNDERSTANDING THE PROCESSES THAT GOVERN THE FLOW OF CARBON AMONG THE OCEAN ATMOSPHERE AND BIOSPHERE IS CRUCIAL TO PREDICTIONS OF ATMOSPHERIC CO2 CONCENTRATIONS AND ITS CONSEQUENCES TO FUTURE CLIMATE. WE PROPOSE TO UTILIZE TEMPORALLY AND SPATIALLY DENSE REMOTE SENSING OBSERVATIONS OF TOTAL COLUMN CO2 (DENOTED XCO2) FROM THE TOTAL CARBON COLUMN OBSERVING NETWORK (TCCON) AND NASA S ORBITING CARBON OBSERVATORY (OCO-2) SATELLITE TO INFER REGIONAL-SCALE BIOSPHERIC FLUXES. WE WILL CONTRIBUTE TO QUANTIFYING THESE FLUXES FROM XCO2 OBSERVATIONS BY (1) QUANTIFYING THE IMPRINT OF ATMOSPHERIC TRANSPORT ON THE TEMPORAL AND SPATIAL VARIABILITY OF XCO2 MEASUREMENTS (2) USING KNOWLEDGE OF CONTEMPORARY TRANSPORT AND CARBON FLUXES TO PREDICT HOW XCO2 MEASUREMENTS WILL CHANGE IN FUTURE CLIMATES AND (3) QUANTIFYING THE IMPRINT ON XCO2 LEFT BY EMISSIONS FROM WILDFIRES AND BIOMASS BURNING AND USING STATISTICAL LEARNING TECHNIQUES TO PROVIDE MORE REALISTIC PREDICTIONS AND ESTIMATES OF EMISSIONS FROM WILDFIRES AND BIOMASS BURNING.
