The Eastern North Atlantic (ENA) central facility is periodically affected by episodes of local aerosols. High-concentration aerosol events associated with potential local aerosol sourcesare sampled by the Concentration Particle Counter (CPC) and can be observed in the high-time-resolution data. In an effort to remove aerosol data that is not regionally representative from the CPC data, an aerosol mask (ENA-AM)has been previously developed and validated during the ACE-ENA campaing (Gallo et al., 2020). TheENA-AM is a standard deviation algorithm based on the statistically different behavior of adjacent data points used to determine periods when the measurements are impacted by local aerosols. Thisfilecontain one-minute time resolutionsubmicron aerosol particle concentration datasets from the CPCfor the year2018, and the correspondingENA-AM datasets to remove datapoints affected by local aerosol sources.
