Description:Gas-phase volatile organic compounds (VOCs) we re measured at three vertical levels between 0.6 m and 5.4 m in the Arctic boundary layer in Barrow, Al aska, for the Ocean-Atmosphere-Sea Ice-Snowpack (OASIS)-2009 field campaign during March –April 2009. C 4-C8nonmethane hydrocarbons (NMHCs) and oxygenated VOCs (OVOCs), including alcoh ols, aldehydes, and ketones, were quanti fied multiple times per hour, day and night, during the campaign using in situ fast ga s chromatography-mass spec trometry. Three canister samples were also collected daily and subsequently analyzed for C 2-C5NMHCs. The NMHCs and aldehydes demonstrated an overall decrease in mixing ratios during the experiment, whereas acetone and 2-butanoneshowed increases. Calculations of time-i ntegrated concentrations of Br atoms, ∫[Br]d t, yielded values as high as
