The analysis of atmospheric aerosol observation data at Kanazawa, Japan from 2003 to 2005

Abstract

We made the operational sky measurements for two and half years from April 2003 to September 2005, using the sky radiometer and presented the analized results of the aerosol optical properties over Kanazawa area, Japan, namely, the optical thickness τ a (500) at the wavelength of 0.5µm and Ångström exponent α. The reflectance ratios between the visible and short wave infrared bands were computed for typical ground covers, such as the vegetation, urban, and others (soil and sand), using several image data sets of Terra/MODIS and these sky observation data sets.
