Particle number size distributions (10-461 nm) measured by SMPS at the ENA site during the AGENA campaign

Overview:

During the Aerosol Growth in the Eastern North Atlantic (AGENA) campaign at the ENA site, particle number size distributions ranging from 10.6 to 461 nm were measured using SMPS with a time resolution of 4 minutes. The local pollution was identified and flagged by the “pollutionflag” field, where 0 denotes the clean periods and 1 denotes the polluted periods.

Abstract:

During the Aerosol Growth in the Eastern North Atlantic (AGENA) campaign at the ENA site, particle number size distributions ranging from 10.6 to 461 nm were measured using SMPS with a time resolution of 4 minutes. The local pollution was identified and flagged by the “pollutionflag” field, where 0 denotes the clean periods and 1 denotes the polluted periods.
Purpose:

This dataset offers basic information on aerosol size distribution and its evolution during the campaign, enabling the further exploration of aerosol growth events in the remote marine boundary layer.

Data Quality:
Attribute Accuracy: No formal uncertainty assessments were conducted and no estimates of uncertainty are reported.
Positional Accuracy: No formal positional accuracy tests were conducted
Consistency and Completeness Report: Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Factor Affecting the Research: The local anthropogenic pollution frequently affected the aerosol observations, causing extremely high concentrations. These polluted periods are flagged by the "pollutionflag" field in the file. Users are advised to remove the polluted data.
Use Restrictions: No use constraints are associated with this data.
