Short summary

The quantification of anthropogenic emissions with current CO₂ satellite sensors is difficult, but NO₂ is co-emitted, making it a suitable tracer of recently emitted CO₂. We analyze enhancements of CO₂ and NO₂ observed by OCO-2 and S5P and estimate the CO₂ plume cross-sectional fluxes that we compare with emission databases. Our results demonstrate the usefulness of simultaneous satellite observations of CO₂ and NO₂ as envisaged for the European Copernicus anthropogenic CO₂ monitoring mission
