The Cocotohai Cryosphere Observation and Research Station (Cocotohai Station), located in Cocotohai Town, Fuyun County, Xinjiang, was established in August 2011, and in 2020, it entered the field station construction sequence of the State Key Laboratory of Cryosphere Science. Up to now, Cocotohai Station has formed a systematic field observation network covering the two river source areas of Altai Mountains, with snow and permafrost monitoring as the main part. The field observation sites of CocoTokai Station are mainly located in the south slope of Altai Mountains, and the source areas of the Irtysh and Ulungu Rivers (the two river source areas). This area is located in the area of strong action of the westerly wind and the Arctic polar vortex, and belongs to the Arctic Ocean water system (the Irtysh River is the only river in our country that flows into the Arctic Ocean), and is the demarcation line between the arid zone of Central Asia and the cold zone of Siberia in the Arctic. The southern slope of Altai Mountains is one of the three major snow areas in China, and also the southern boundary region of the northern hemisphere latitude perennial permafrost, rich snow and permafrost resources significantly affect the Altai Mountains and even the northern border region of water and ecological environment security. For this reason, with the joint support of the State Key Laboratory of Cryospheric Science, the State Key Laboratory of Permafrost Engineering, the National Glacier, Permafrost and Desert Science Data Center, the Two Rivers Nature Reserve of Altay Mountains in Xinjiang, the Altay Hydrographic Survey Bureau, and the Erqis River Basin Construction Management Bureau, the Cocotocai Station has carried out systematic monitoring of meteorology, snowpack, and permafrost in the Altay Mountains and Two Rivers area, and has accumulated a wealth of data and information. The field monitoring platform of the Cocotocai Station will provide basic scientific research data support for the prevention and control of snowmelt floods in the Irtysh River Basin, the efficient utilization of water resources in the northern Xinjiang region, and the monitoring and protection of the ecological environment of the Altai Mountains.
