Posterior model-observation mismatch at nine INFLUX towers. Left: Modeled CO2 enhancement as a function of observed CO2 enhancement for the Hestia prior (blue), ODIAC posterior (green), iODIAC posterior (orange), and the 1-to-1 line (black dashed). Numbers indicate data point for individual sites. Right: Posterior model-observation mismatch at nice INFLUX towers for the Hestia posterior (blue), ODIAC posterior (green), iODIAC posterior (orange). The site number is shown in the upper right corner of each plot and the black circles indicate the locations of the sites. Open black circles indicate the location of the power plants within the city. The y-axis for each plot extends from –1 to +1 ppm CO2. The observation are not available for this time period at Site 06, 08, 11 and 13. DOI: https://doi.org/10.1525/elementa.146.f5
