Short summary
Vanillic acid is reported in the Tunu ice core from northeastern Greenland. It is an aerosol-borne acid produced by biomass burning. North American boreal forests are likely the source regions of the vanillic acid deposited at the ice core site. Vanillic acid levels were elevated during warm climate periods and lower during cooler climate periods. There is a positive correlation between the vanillic acid ice core record and ammonium and black carbon in the NEEM ice core from northern Greenland.
