Abstract

We investigated the remote sensing of aerosol optical properties at ground-based and mountain site by using the Sky radiometer (POM-01, 02: PREDE Co. Ltd., Tokyo, Japan.). Our objectives were to understand the effect on the earth climate change and radiative forcing based on height difference observation of aerosol optical properties. These data have revealed various some events and seasonal trend. However, there are still some things to consider in different observation environments, effect of cloud and climatic conditions, such as changes in some parameters (surface albedo, atmospheric pressure, and so on). Based on height difference observations, we are conducting different research (Atmosphere, Ocean, Cryosphere, Land) to proposals for next validation and analysis, focusing on the wavelength dependence of optical properties by solar radiation. We provide the wavelength dependence of solar aureole, in this presentation, on the aerosol optical properties measurements with vertical variability based on height difference at two area of Toyama and Nagasaki, Japan. Toyama area (Toyama (TOY: 36.699N, 137.187, alt. 30m) and Mt. Jodo (JOD: 36.566N, 137.606E, alt. 2839m)) is located in the center of Japan, near the Toyama Bay on the cost of Sea of Japan. Nagasaki area (Nagasaki (NGS: 32.786N, 129.865E, alt. 35m) and Mt. Unzen-Nita (UZN: 32.751N, 130.286E, alt. 1100m)) is located in the south-west part of Japan. Both areas are observed to be affected by Asian dust, anthropogenic aerosols, and volcanic eruptions. In this presentation, on the aerosol optical properties measurements with temporal and spatial variability.
