Atmospheric aerosol has a potential to change the global climate by the direct and indirect effects on the radiation balance in the planetary atmosphere. The direct effect is generally expected to be small in the polar regions, but the indirect effect may cause a large difference of cloud optical properties between the Arctic and Antarctic regions. National Institute of Polar Research promotes the atmospheric research in both polar regions, and employs remote-sensing instruments for aerosol and cloud studies. For investigating the columnar aerosol optical properties, sky-radiometry based on a radiation inversion algorithm is powerful to retrieve the aerosol volume size distribution, single scattering albedo and complex refractive index as well as aerosol optical thickness and Angstrom exponent. In order for long-term monitoring of the aerosol properties, we are operating a Prede POM-02 skyradiometer at Syowa Station （69.0N, 39.6E） in Antarctica. Also we recently developed a new skyradiometer POM-01 MK III for ship-based measurements. In this paper, we will show preliminary results from surface-based and ship-based skyradiometer measurements during winter-over research activities at Syowa Station and the Antarctic cruises by Icebreaking R/V Shirase of the Japanese Antarctic Research Expeditions.
