10-year trends of particle size distributions and equivalent black carbon at the Environmental-Climate Observatory (ECO) in Lecce (Italy).
This study investigates the long-term (2015-2024) inter-annual and seasonal trends of PM2.5, coarse particles (PM10-2.5), particle number size distribution (PNSD, 10-10,000 nm), and equivalent black carbon (eBC) at the ECO Observatory in Lecce (Southern Italy) measured with online instruments.
