Hydrofluorocarbons (HFCs) and SF₆ are industrially produced gases with a large greenhouse-gas warming potential. In this study, we estimated the emissions of HFCs and SF₆ over Europe by combining measurements at three background stations with four different model systems. We identified significant differences between our estimates and nationally reported numbers, but also found that the network of only three sites in Europe is insufficient to reliably attribute emissions to individual countries.
