英文摘要	Snow plays an important role in the Earth's energy balance, causing more solar radiation to be reflected back into space compared to most snow-free surfaces. This chapter provides a brief overview of the remote sensing of snow cover using visible and near-infrared (VNIR) and passive microwave (PM) data. Snow can be mapped using the microwave part of the electromagnetic spectrum, even in darkness and through cloud cover, although at a coarser spatial resolution than when using VNIR data. Fusing VNIR and PM algorithms to produce a blended product offers synergistic benefits. Snow-water equivalent (SWE), snow extent, and melt onset are important parameters for climate models and for the initialization of atmospheric forecasts at daily and seasonal time scales. Snowmelt data are also needed as input to hydrological models to improve flood control and irrigation management. © 2015 by JohnWiley & Sons, Ltd. All rights reserved.
