Analysis of atmospheric aerosol observation data in Kanazawa, Japan from 2003 to 2005

摘要

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 Angstroem 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.
