Overview of FY-3 Snow Monitoring Products and Applications in Remote Sensing Service

In this paper, main imaging sensors of FY-3 and snow monitoring products are firstly introduced. FY-3 meteorological satellites have the ability of global snow monitoring. Snow parameters include snow cover, snow depth and snow water equivalent can be produced from FY-3 level-1 data. For the payloads of FY-3, visible and near-infrared sensor provides information of snow cover, and passive microwave sensor provides information of snow depth and snow water equivalent. Then, in terms of disaster prevention, disaster mitigation and climate change response, the applications of snow monitoring products in remote sensing service are respectively introduced. Finally, the prospects of snow monitoring by using FY-3 data are discussed based on the development of snow remote sensing monitoring technology at home and abroad. It is proved that snow monitoring products of FY-3 can provide objective, reliable, comprehensive and near-real-time reference information.
