Organic tracers from biomass burning in snow from the coast to the ice sheet summit of East Antarctica by Shi, G., Wang, X., Li, Y., Trengove, R., Hu, Z., Mi, M., Li, X., Yu, J., Hunter, B., He, Tianhua

“…Here, using ultra-high-performance liquid chromatography-tandem mass spectrometry techniques, we quantified three organic compounds (levoglucosan, vanillic, and syringic acids) released by biomass burning in snow samples collected along a 1250-km transect from the coast to the ice sheet summit Dome A in East Antarctica. Results indicate that these tracers are ubiquitous and have reached the ice sheet summit from the continental emissions in the Southern Hemisphere. …”
