Nalini, P. Ciais, C. Abdallah, and T. Lauvaux were supported by the French program Make Our Planet Great Again (project CIUDAD, CNRS). We acknowledge the French monitoring network for greenhouse gases (SNO-IFA) coordinated by LSCE-OVSQ (M. Ramonet and O. Laurent) for providing the data for the study. K. Nalini performed the inversions using the inversion system developed by T. Lauvaux. J. Lian performed the WRF-Chem model outputs for the LPDM simulations and inversion, C. Abdallah provided the LPDM trajectory outputs, H. Utard developed and prepared the Origins.Earth emission product. P. Ciais provided comments and discussed the results of the study. |

Popis: | International audience; • Quantification and mapping of fossil fuel CO 2 emissions over the Paris metropolitan area during the COVID-19 pandemic lockdown • Lockdown has resulted in an emission decrease of about 43% in 2020, with a 37% contribution from the inventory itself • Spatial error correlations, different background conditions and prior uncertainty impact the posterior emission estimates |
