Cold regions (including high-latitude and high-elevation landscapes) and areas of permafrost and glacial ice cover, are experiencing ecosystem changes caused by global warming. Remote sensing has become increasingly important for monitoring and understanding the patterns and mechanisms of change in cold region ecosystems where the frozen season is a significant constraint on eco-hydrological processes and functionings. Recent advances in remote sensing include the development of new sensors (multispectral, hyperspectral, thermal, microwave, SAR, and SIF), airborne platforms (UAVs), and big data analytics. These technologies provide many opportunities to quantify hydrological, ecological, and cryospheric variables with characterizing cold region ecosystems. The aim of this Special Issue is to collect state-of-the-art research in remote sensing technology and applications of cold region ecosystems. Studies using multi-scale and multi-component data (in-situ measurements, satellite observations, and modeling) are also welcome. Submissions on the following topics are invited (but not limited to):

• Remote sensing of cold region ecosystems, including ecosystem productivity, phenology, greening/browning, evapotranspiration, and arctic species distribution;
• Tundra vegetation ecology, boreal ecosystem ecology, boreal wetlands;
• Land cover/land use change;
• Disturbance and recovery of cold region ecosystems;
• Landscape freeze/thaw status;
• Remote sensing of snow/ice, permafrost;
• Remote sensing of water bodies;
• Glacial mass, movement, and melting;
• Multiple scale monitoring (field/plot, landscape, regional) and bottom-up scaling;
• Application of new algorithm, comparison/evaluation of methods.
