Total aerosol and black carbon number concentration measured at the Eastern North Atlantic observatory in autumn 2020

The 6-hour time-averaged total particle concentration was measured with a condensation particle counter (CPC), and the 6-hour time-averaged mass concentration of black carbon was measured by a particle soot absorption photometer (PSAP). All measurements are from the Eastern North Atlantic Ocean (ENA) study period (2020). The measurement accuracy of CPC and PSAP is presumably dominated by inlet flow variability of 5%.
