Description

This collection includes separate data sets of atmospheric aerosol submicron particle composition that include organic functional group concentrations at locations within the Arctic. Measurements include analysis of ambient aerosol particles sampled on Teflon filters that were analyzed by Fourier transform infrared (FTIR, Bruker Tensor 27) spectroscopy in a temperature and humidity controlled clean room. The FTIR spectrum for each filter was analyzed with an automated algorithm that baselined the spectra. Absorptivity and molar masses were used to convert peak area at specific wavenumbers to mass for the organic functional groups: hydroxyl, alkane, amine, carboxylic acid, and carbonyl. The total organic mass (OM) is calculated as the sum of the concentrations of the organic functional groups. Some filters were also analyzed by Chester laboratories for X‐ray fluorescence (XRF) spectroscopy to quantify elemental concentrations.
