摘要
积雪在全球水文和气候变化中扮演着十分重要的角色。利用遥感技术进行积雪监测已有40多年的研究历史,在雪盖制图、雪深反演、冰雪反照率等方面发展了一系列的算法及产品。其中,光学遥感以其高时空分辨率的特点在积雪监测中得到了非常广泛的应用。随着对地观测系统(Earth Observation System,EOS)的发展,以及国产环境卫星的陆续升空,越来越多的遥感数据被应用于积雪监测,遥感技术势必在积雪监测领域发挥更加重要的作用,为模拟地球辐射平衡、地表水文研究、全球变化等提供丰富的数据资料。
Snow plays a very important role in global hydrology and climate change. Using remote sensing technology in snow cover monitoring has a history of more than 40 years. A series of algorithm and products were developed in the snow cover mapping, snow deeps inversion and snow-ice albedo. Among them, the optical remote sensing data were used widely in snow cover monitoring because of their high resolution in time and space. As the earth observation system （EOS） developed and domestic environmental satellite launched in succession, more and more remote sensing data will be used in the snow monitoring field, and provide abundant data source for earth radiation balance simulation, surface hydrologic, and global change researches.
