“…Inverse systems designed to constrain fluxes on these scales typically incorporate a global chemical transport model that assimilates estimates of the atmospheric CO 2 dry air mole fraction with an optimization algorithm that derives estimates of the net surface CO 2 fluxes needed to match the observed CO 2 distribution to within its uncertainties in the presence of the imposed wind field (Baker, Doney, & Schimel, 2006; Bousquet et al., 2000; Enting, 2002; Enting et al., 1995; Peters et al., 2005). Studies of anthropogenic emissions from point sources or large urban areas typically employ simpler emission plume mass balance models (Nassar et al., 2017, 2021; Reuter et al., 2019; Varon et al., 2018) although some use more sophisticated inverse models with Eulerian (Lei et al., 2021; Ye et al., 2020) or Lagrangian transport schemes (Wu et al., 2018). Both types of systems are summarized here.…”

“…Space-based sensors do not yet have the coverage needed to track all local sources, but they do provide opportunities to assess the precision that could be delivered by future space-based instruments. For example, Nassar et al (2017Nassar et al ( , 2021 used OCO-2 XCO 2 estimates to quantify emissions from individual coal-fired power plants (Figure 4). They combine these estimates with wind speed and direction from ERA-5 (Hersbach et al, 2020) and MERRA-2 (Molod et al, 2015) in a simple Gaussian plume model to estimate the fluxes.…”
