Abstract One of the main sources of organic aerosols (OA) is biomass burning. In particular, during winter, residential burning is likely to dominate over wildfires and prescribed burning. Therefore, in the winter, it is important to be able to determine the contribution of residential biomass burning to the total OA concentration. Smoke marker measurements provide one of the most common methods to make this determination. The Wintertime Investigation of Transport, Emissions, and Reactivity (WINTER) Campaign provided an opportunity to explore this as it was an aircraft-based study aimed at examining daytime and nighttime wintertime chemistry along the East Coast of the United States. Therefore, we collected levoglucosan data, a smoke marker, from aboard the C-130 aircraft during the 13 research flights. Results were obtained by coupling a Particle-into-Liquid Sampler (PILS) with a fraction collector to provide off-line samples for levoglucosan analysis by high-performance anion-exchange chromatography with pulsed amperometric detection. In this work, results from these measurements will be presented. The correlation of levoglucosan with OA and carbon monoxide will be explored. A determination for the contribution of residential biomass burning across the sampling region will be provided.
