A total of 126 weekly averaged observations of submicron-particle chemistry andparticle microphysics made at the Dr. Neil Trivett Global Atmospheric Watch Observatory at Alert, Nunavut (82.5°N, 62.5°W; elevation 210 m a.m.s.l.) from April 2012 to October 2014. Teflon filters (Teflo, Gelman Sciences, Ann Arbor, MI) were collected once a week after a 1.0 μm cyclone (SCC, Rupprecht & Patashnick, East Greenbush, NY). A Bruker Tensor 27 FTIR spectrometer with a deuterated triglycine sulfate (DTGS) detector (Bruker, Waltham, MA) was used to scan the filters both before and after sampling. The baselined spectra are provided for each sample including filter number, start and stop times, wavenumber, and absorption. Filters were loaded in a wooden box outside of the Alert sampling station to minimize losses due to vaporization of higher vapor pressure components and reactions that could change organic composition during storage. An automated algorithm was applied to quantify the mass of the organic functional groups [Russell et al., 2009; Takahama et al., 2013]. Five functional groups are included: Alkane, Amine, Alcohol, Carbonyl and Carboxylic acid groups. Other groups (Organosulfate, Organonitrate, Aromatic and Alkene group) were also fit but more than 80% of the samples were below detection limit.
