| Abstract | Snow plays an important role in the energy and water balance of drainage basins in alpine regions. Contribution of snowmelt to runoff is one of the important water resources in mountainous regions, in addition to rainfall and glacier melt. Snow stores at least one-third of the water usage for irrigation and growth of crops worldwide. Snow covered area and snow depth/water equivalent estimations are important parameters for regional climate change studies, agriculture, and water resource management. Traditional in situ measurements provide critical snow observations in limited areas and for calibration and validation (cal/val) of remotely sensed estimation of snow parameters. Satellite-based snow measurements have revolutionized the monitoring of spatiotemporal variations of snow cover and snow depth/water equivalent in complex natural conditions at regional and global scales. This special section provides a picture of state-of-the-art research in snow remote sensing, algorithm development and improvement, and snow modeling and application. It includes 20 papers that cover four major topics: snow cover and snow depth/snow water equivalent (SWE) mapping using optical and passive microwave remote sensing (10 papers), algorithm developments for snow cover and glacier mapping (6 papers), snow cover and snow melt-runoff modeling (3 papers), and one review paper. Many of the papers are extended versions of materials that were presented in the first Snow Remote Sensing of China Workshop (Lanzhou, China, August 2013). The review paper “Remote sensing for snow hydrology in China: challenges and perspectives” by Wang et al. (CID 084687) provides a detailed summary of the development of snow remote sensing, snow parameters retrieving and applications in China since the 1980s. In particular, since 2007, two major large-scale field-based experiments: (1) Watershed Allied Telemetry Experimental Research (WATER) in the Heihe River Basin of Northwest China and (2) Cooperative Observation Series for Snow Properties in three major snowfall regions (Northwest China, Northeast China and the Tibetan Plateau), have been initiated and have obtained many first-hand data for algorithm development and validation of remotely sensed snow parameters retrievals. One particular application of remote sensing snow products in China is the early warning system of snow-caused livestock death (disasters) in pastoral areas. The system is a unique application and development, particularly for undeveloped high mountainous areas such as the Tibetan Plateau (TP), where mean elevations are over 4000 m and there is little or no infrastructure and industry. There are 10 papers about snow cover and snow depth/SWE mapping and applications. Of these, 5 papers use optical remote sensing, primarily MODIS snow cover products; 4 papers use passive microwave remote sensing; and one paper evaluates the accuracy of the U.S. National Ice Center’s Multisensor Snow and Ice Mapping System (IMS) snow cover product in China. Two papers by Chen et al. and by Li and Ke present applications of different MODIS snow cover products for northeast China. Both find an increased trend of snow covered area (SCA) in the most recent 10 years, primarily correlated with the recent decreased tendency of air temperature in the region, although there is a clear long-term increased trend of air temperature since 1960. The recent decreasing trend in air temperature in the region is interesting and deserving offurther |
