Short summary

This study presents the absorption enhancement of internally and externally mixed black carbon (BC) particles in a Mediterranean city and countryside. We showed the importance of secondary organic aerosols (SOAs) and particle ageing by increasing the BC absorption enhancement. We performed a trend analysis on the absorption enhancement. We found a positive trend of the absorption enhancement at the regional station in summer driven by the increase over time of the relative contribution of SOA.
