Black carbon aerosol measurements at Cataract Scout Park, Australia, taken during the COALA-2020 campaign

Measurements of black carbon aerosol were collected using a multi-angle absorption photometer (MAAP 5012, Thermo Fisher Scientific, Waltham, MA, USA). Measurements were taken at Cataract Scout Park, Appin, N.S.W. (34°14'42.29"S 150°49'24.97"E) from an inlet 4.8 m above ground level as part of the Characterizing Organics and Aerosol Loading over Australia (COALA-2020) campaign. The instrument was operated using a sample flow rate of 1000 L/hr (16.67 LPM). The inlet was not heated. It was fitted with a PM10 cap, restricting the measured aerosol to diameters less than 10 µm. Measurements are taken at 1-minute time resolution, as reported here. Flagged measurements have been removed, except for the "Temperature error" flag. This flag was persistent throughout the campaign and relates to the use of a non-heated inlet. Measurements below 0.0005 ug/cm3 have been removed as this is below the detection limit of the instrument. Instrumental details and calculation of aerosol absorption coefficient can be found in Petzold et al. (2002)
