Paper Abstract

In recent years, with the frequencies and intensities was increasing in environmental issues, much more attentions were focus on sandstorm in the fields of natural science and social science research. The geostationary satellite imagery can continuously observe the surface of the earth in a short period of time, and has a good monitoring advantage for the sand- dust, which has a fast-moving target. Based on the geostationary meteorological satellite data of Himawari-8(H8) at 4:00 on May 3, 2017, the results of remote sensing retrieval of sand-dust intensity are compared by using a variety of exist sand- dust identification models. The results show that the multi-channel threshold method has the best effect on sand-dust identification, the reflected radiation dust index method is the second, and the infrared split window channel difference method and the infrared split window channel ratio method have the worst identification effect. Single channel threshold method, infrared multi-channel threshold method, infrared split window channel difference method and infrared split window channel ratio method have poor distinction between cloud layer and sand dust, multi-channel threshold method and reflected radiation dust index method are poor distinguished between low temperature zone and the sand-dust.
