Abstract:
We propose to apply a high-resolution regional inverse modeling framework to quantify
CO2 fluxes that are optimally consistent with surface, aircraft, and satellite data, both
current and planned. We will develop objective metrics for weighting the data and use a
Lagrangian atmospheric transport model to compute a library of footprints corresponding
to the various sources of CO2 observations. We will investigate consistency among the
available datasets, taking into account uncertainties caused by satellite retrieval errors and
model inadequacies, such as errors in simulated atmospheric transport and structural and
numerical limitations of current inversion approaches (particularly when applied to the
large volume of satellite data). This work fosters collaboration between Federal agencies,
academia, and private industry engaged in greenhouse gas research and monitoring and
leverages multiple NASA- and USGCRP-funded efforts to obtain measurements of
atmospheric CO2 and develop regional-scale inverse modeling tools for quantifying
carbon dioxide fluxes and their uncertainties. The proposed work will inform the
development of the NASA Carbon Monitoring System (CMS) Flux Product, in particular
regarding strategies for incorporating diverse CO2 observations and quantifying fluxes at
policy-relevant scales. The proposed data products will be directly useful for evaluating
the current CMS Flux Product.
