Chemical properties measurements of aerosols were made over a few years in Tiksi, Norilisk and Yakutsk, Siberia. Results at Tiksi indicate a strong seasonal variation, high concentration in late winter to early spring and low value in summer, and that the major component of aerosols is sulfate. These results suggest that Siberian Arctic have been also poluted by Arctic Haze as well as other Arctic region. Optical properties of Siberian Arctic Haze were calculated using scattering theory of Mie. And also upward radiative flux from the top of atmosphere was estimated based on the optical properties. Furthermore, possibility of application of infrared remote sensing to Arctic haze was discussed.
