内容 研究概要:Arctic Study of Tropospheric Aerosol and Radiation (ASTAR2000) were conducted in March and April 2000. The principal objectives of ASTAR2000 were to observe and clarify the behavior of tropospheric aerosols, especially of the "Arctic haze", and their radiative effects. During the ASTAR2000, we carried out aerosol profile measurements with a Micro Pulse Lidar (MPL) and sky radiance measurements with a Sky-radiometer at Ny-Alesund (79N, 12E). Svalbard. The MPL is a useful tool to observe the temporal and spatial aerosol behavior, while the Sky-radiometer measures the. sky radiance and can provide information on aerosol properties such as size distribution, scattering phase function, optical depth, Angstrom parameter, and refractive index. These instruments worked well during the campaign and we could observe representative features of the Arctic haze events. In the case of Arctic haze on the ground level, the height of the mixing layers was limited in the lower altitude with relatively small value of the Angstrom parameter. In contrast, when the haze layer was found in the higher atmosphere, the mixing layer height could not be distinguished clearly, and the Angstrom parameter exhibited larger values. This result is interpreted in relation to the aerosol transport.
