Abstract
Abstract. We examine the impact of different sources of ozone
precursors on the daily evolution of successive ozone pollution outbreaks
across Europe in July 2017 by using a multispectral satellite approach
called IASI+GOME2 and a tropospheric chemistry reanalysis named TCR-2.
IASI+GOME2, combining IASI (Infrared Atmospheric Sounding Interferometer)
and GOME-2 (Global Ozone Monitoring Experiment-2) measurements respectively
in the infrared and the ultraviolet, allows the observation of the daily
horizontal distribution of ozone in the lowermost troposphere (defined here
as the atmospheric layer between the surface and 3 km above sea level).
IASI+GOME2 observations show a fair capacity to depict near-surface ozone
evolution as compared to surface measurements from 188 European stations for the period 15–27 July 2017. At the beginning of this event (on 16 July), an ozone outbreak is initially
formed over the Iberian Peninsula likely linked with high
temperature-induced enhancements of biogenic volatile organic compound
concentrations and collocated anthropogenic emissions. In the following
days, the ozone plume splits into two branches, one being transported
eastward across the western Mediterranean and Italy and the other one over
western and Central Europe. The southern branch encounters ozone precursors
emitted over the Balkan Peninsula by wildfires along the coast of the
Adriatic Sea and biogenic sources in the inland region of the peninsula.
Ozone concentrations of the northern plume are enhanced by photochemical
production associated with anthropogenic sources of ozone precursors over
Central Europe and by mixing with an ozone plume arriving from the North Sea
that was originally produced over North America. Finally, both ozone
branches are transported eastwards and mix gradually as they reach the
northern coast of the Black Sea. There, emissions from agricultural fires
after harvesting clearly favour photochemical production of ozone within the
pollution plume, which is advected eastwards in the following days. Based on satellite analysis, this paper shows the interplay of various ozone
precursor sources to sustain a 2-week-long ozone pollution event over
different parts of Europe.
