Abstract. This paper reports on the transport of ozone (O3) and related species over the North Atlantic ocean and its im-pact on Europe. Measurements of nitrogen dioxide (NO2) and carbon monoxide (CO) columns from the GOME and MOPITT satellite instruments, respectively, are used in con-junction with the GEOS-CHEM global model of transport and tropospheric chemistry to identify the major events of long range transport that reach Europe over the course of summer 2000. Sensitivity model simulations are used to analyse observed O3 distributions with respect to the im-pact of long range transport events. For that purpose, we used in-situ O3 observations taken at the mountain site of Jungfraujoch as well as O3 vertical profiles taken in the vicin-ity of central European cities. Over the course of summer 2000, we identified 9 major episodes of transatlantic pol-
