| Outline of Final Research Achievements |
The objective of this research is to improve the accuracy of Aerosol Optical Thickness(AOT) and Single Scattering Albedo(SSA) estimated in the SKYNET (http://atmos.cr.chiba-u.ac.jp/). The SSA has had a trend of a little overestimation compared with other data. In this research, both viewpoints of hardware and software in the SKYNET observation/analysis system are re-examined in detail. The newly developed spectro-pyranometer has been introduced for comparison of AOT and SSA with SKYNET products, and the calibration system has been also examined using an integrating sphere which is operated in AERONET/NASA. As a result, the most plausible reason of the overestimation of SSA in the SKYNET might be due to the small underestimation of the solid-view-angle of sensor of sky radiometer. Based on this result, a new calibration and revised method is proposed.
