Description:	This file contains a summary of the total mass and chemical composition of coarse (10-2.5 μm) and fine (<2.5 μm) aerosol particles collected from Tuktoyaktuk, NWT during July-September 2018 using an AirPhoton Assembly, as described by Snider et al. (see related publication). Anions and cations were analyzed using ion chromatography with conductivity detection, and metals were analyzed by inductively coupled plasma-mass spectrometry (ICP-MS). An overview of method details is discussed by Snider et al. The system was mounted approximately 3.5 m above ground level at the Aurora College Community Learning Centre. Notes: the uncertainty of total mass is based on the error propagation associated with replicate filter weighing before and after sample collection. The mass of ions and metals in sample extracts was determined by multiplying extract concentrations (μg/mL or ng/mL) by the total extraction volume, which was 3 mL, and a factor of 2 to account for the mass on the entire filter. For the chemical composition analysis, the less-than sign is used to indicate when the masses of ions and metals are below their detection limit. Due to a file writing error during the study, the sample volume could not be determined and only the absolute mass collected on the filters is provided.
