Outline of Final Research Achievements

Infrared radiation sensor IIR on NASA satellite CALIPSO is used to detect the yellow sand concentration in Asia based on the IR split window method. In this study, we used the space Mie-Lidar CALIOP mounted on CALIPSO. We also applied the yellow sand transport model to examine the dust retrieved results. We found that the IIR split window method can detect the dust over the Taklimakan desert area however the detection accuracy decreased over the Japan area because of low dust concentration of high atmospheric humidity condition.
