Abstract

The invention relates to the technical field of atmospheric environment monitoring and particularly relates to a sand storm monitoring method based on multi-source satellite remote sensing data. The sand storm monitoring method for monitoring sand storm more accurately comprises the following steps: obtaining satellite detecting initial data; calculating a ratio of a near-infrared albedo to a visible light albedo in the initial data, and calculating a difference value between an infrared brightness temperature and a thermal infrared brightness temperature in the initial data; performing brightness temperature calculating of two wavebands of an infrared splitting window on the initial data; if the calculated results of the ratio, the difference value and the brightness temperature calculated results of the infrared splitting window are within corresponding regions, indicating the identified results as a sand storm region.

Description

technical field [0001] The invention relates to the technical field of atmospheric environment monitoring, in particular to a sandstorm monitoring method based on multi-distant satellite remote sensing data. Background technique [0002] Sandstorms are a relatively common natural phenomenon caused by special geographical environment and meteorological conditions. They mainly occur in deserts and their adjacent arid and semi-arid areas. North Africa, the Middle East, Central Asia, South Asia, East Asia, North America, and Australia are The world's main sandstorm occurrence areas, the western part of my country is a part of the Central Asian sandstorm area, and the northern part of China is a part of the East Asian sandstorm area. The frequent occurrence of sandstorms is one of the important signs of environmental deterioration. Sandstorms are a meteorological disaster and a serious ecological environment problem. According to the definition of meteorology, sand and dust weath...
