Abstract:
Our project goal is to experiment utilize continental, regional and urban-scale in situ CO2 observational networks and associated atmospheric analyses to evaluate OCO-2 observations. In particular we will apply tower-based observations and atmospheric inversions from North America, the U.S. Midcontinent Intensive, an upcoming Gulf Coast intensive, and the ongoing Indianapolis flux experiment to compare to OCO-2 observations. We will attempt to use OCO-2 observations, in combination with the tower-based observations described above, to infer CO2 fluxes using atmospheric inversions at continental, regional and urban scales. We will thus evaluate observing strategies for quantification of both sinks and discrete sources of CO2. This work will be highly leveraged by existing research activities which include first-hand data collection, the development of innovative inversion methodology, and assessing and ultimately reducing uncertainty in atmospheric inversions. This work will be focused primarily on regions where existing observations are currently dense and inventories are relatively well developed, thus providing strong sites for calibration and testing of OCO-2’s capabilities. The information gleaned from these intensely instrumented domains should be applicable to regional studies using OCO-2 at many similar locations around the world where in situ data are less abundant.
