Seasonal Variation of Atmospheric Aerosols above Tokyo-Bay Area

Abstract

This study installed a sky radiometer in Yokohama City in order to make clear the optical characteristics of aerosols above the Tokyo Bay area.

The observed values were evaluated by month, and the aerosol optical thickness tended to be high in April, and the value varied in August. A point-to-point comparison showed that the single scattering albedo at Yokohama was lower than that at the surrounding sites, and the angstrom exponent was higher than that at the surrounding sites.
