Investigating New Particle Formation and Growth Over an Urban Location in the Eastern Mediterranean.

ABSTRACT: This study investigates the new particle formation (NPF) events at an urban location in the Eastern Mediterranean. Particle size distribution, particulate chemical composition, and gaseous pollutants were monitored in Rehovot, Israel (31°53″N 34°48″E) during two campaigns: from April 29 to 3 May 2021 (Campaign 1) and from May 3 to 11 May 2023 (Campaign 2), coinciding with an intensive bonfire burning festival. The organic aerosols (OA) source apportionment identified two major factors-Hydrocarbon-like OA and Biomass-burning OA-as well as two secondary factors-MO-OOA (more oxidized-oxygenated OA) and LO-OOA (low oxidized oxygenated OA). NPF events were frequently observed during the day (mostly well-defined nucleation events) and at night (burst of ultrafine mode particles without any disce
