Methane (CH₄) sources in Krakow, Poland: insights from isotope analysis by M. Menoud, C. van der Veen, J. Necki, J. Bartyzel, B. Szénási, M. Stanisavljević, I. Pison, P. Bousquet, T. Röckmann

“…The simulated isotopic source signatures, obtained with Keeling plots on each simulated peak, indicate that a higher contribution from fuel combustion sources in the EDGAR v5.0 inventory would lead to a better agreement than when using CAMS-REG-GHG v4.2 (Copernicus Atmosphere Monitoring Service REGional inventory for Air Pollutants and GreenHouse Gases). The isotopic mismatches between model and observations are mainly caused by uncertainties in the assigned isotopic signatures for each source category and the way they are classified in the inventory. …”
