Outline of Final Research Achievements

Aerosols and clouds play an important role in the Earth climate change. We provide the information, in this presentation, on the aerosol and cloud optical properties with respect to their temporal and spatial variability in the world. The global distributions of aerosols have been derived from earth observation satellite and have been simulated in numerical model, which assume optical parameters. However, these distributions are difficult to derive because of variability in time and space. Therefore, Aerosol optical properties were investigated using the measurements from ground-based and ship-borne sky radiometer. We started the long-term monitoring of aerosols optical properties since 1990’s, by using a sky radiometer. The obtained Aerosol optical properties clearly and slightly showed seasonal and decrease variability. We understand their temporal and spatial variability.
