Title

Biomass burning markers and residential burning in the WINTER Aircraft Campaign

Abstract

As part of the WINTER (Wintertime Investigation of Transport, Emissions, and Reactivity) campaign, a Particle-into-Liquid Sampler with a fraction collector was flown aboard the National Center for Atmospheric Research C-130 aircraft. Two-minute integrated liquid samples containing dissolved fine particulate matter (PM1) species were collected and analyzed off-line for the smoke marker levoglucosan using high-performance anion-exchange chromatography-pulsed amperometric detection to compare levoglucosan with aerosol mass spectrometer (AMS) biomass burning markers and investigate the contribution from residential burning during the study. Levoglucosan was correlated with AMS organic aerosol (R-2=0.49) and with carbon monoxide (CO; R-2=0.51) for all flights. Levoglucosan was not correlated with the inorganic smoke marker water-soluble potassium but was correlated with the AMS markers C2H4O2+ (high resolution, R-2=0.60) and m/z 60 (unit mass resolution, R-2=0.61). However, at low levoglucosan, AMS markers deviated potentially due to interferences from other sources or differences with the species captured by the AMS markers. Analysis of levoglucosan changes relative to carbon monoxide as plumes advected from source regions showed no systematic levoglucosan loss for plumes up to 20hr old. Based on literature residential burning source ratios and measured levoglucosan, contributions of organic carbon (OC) due to residential burning were estimated. The contribution ranged from similar to 30 to 100% of the OC, with significant variability depending on the source ratio used; however, the results show that biomass burning was a significant PM1 OC source across the entire sampling region. A GEOS-Chem model simulation predicted significantly less smoke contribution.
