| Outline of Final Research Achievements |
Aerosol optical properties, the target of our research, depend strongly on the aerosol particle size, and its influence is most remarkable in the forward scattering (scattering with a small scattering angle). However, the measurable scattering angle of conventional instruments are not so small, around 3 deg with angular resolution of 1 deg. In this research, we used a hyperspectral camera and succeeded in measuring radiance distribution around the sun as close as 1 deg with an angular resolution of 0.1 deg. Accordingly, we could obtain more reliable aerosol size distribution. Besides, since we take radiance distribution as images, we can make observation efficiently, and we can distinguish obstacles like clouds easily.
