Anthropogenic CO2 flux constraints in the Tokyo Bay Area from Lagrangian diffusive backward trajectories and high resolution in situ measurements
Description (Dublin Core)
In order to use high resolution in-situ measurements to constrain regional emissions of carbon dioxide (CO<sub>2</sub>), we use a Lagrangian methodology based on diffusive backward trajectory tracer reconstructions. We use aircraft, tall tower and ground sites for CO<sub>2</sub> data collected nearby the CO<sub>2</sub> emission hot spot of the Tokyo Bay Area during the CONTRAIL campaign, from the MRI/JMA Tsukuba tall tower and from the World Data Centre for Greenhouse Gases (WDCGG). We calculated Bayesian inversions based on EDGAR 4 and CDIAC a priori fluxes. Estimated fluxes for the Tokyo Bay Area for the analyzed period between 2005 and 2009 range between 4.80×10<sup>−7</sup> and 3.45×10<sup>−6</sup> kg<sub>CO<sub>2</sub></sub> m<sup>2</sup> s<sup>−1</sup> with significant time variations. Significant differences in retrieved fluxes of up to 21% were found when CONTRAIL measurements were added to the dataset. No significant trend was found in the time series of spatially averaged retrieved fluxes.
