Abstract

This study aims to quantify the contributions to surface ozone (O3) concentration in the Iberian Peninsula (IP) from the main NOx emission sectors in the region along with the imported O3 during a 10-day episode. The work applies an Integrated Source Apportionment Method within the CALIOPE air quality system at 4-km resolution. This study finds that the imported O3 is overall the larger contribution to its surface concentration. Contributions from local/regional sources are decisive in the O3 peaks downwind of main nitrogen oxides (NOx) hotspots in the IP under stagnant conditions.
