Amines in Boreal Forest Air at SMEAR II Station in Finland

Abstract

Abstract. We measured amines in boreal forest air in Finland both in gas and particle phase with 1-hour time resolution relative humidity of air was >90%, gas phase DMA correlated well with 1.1-2 nm particle number concentration (R 2 =0.63)suggesting that it participates in new particle formation. 0.63 EA concentrations were low all the time, July means were <0.36 ng m -3 and 0.4±0.4 ng m -3 in gas and aerosol phase respectively, but they correlated well with monoterpene concentrations in July. Monthly means of PA and BA were all the time below detection limits. 30Atmos. Chem. Phys. Discuss., https://doi
