This special section contains nine selected papers in three groups. One group pertains mainly to Earth observation for ice and snow. “Glacier surface velocity estimation in the West Kunlun Mountain range from L-band ALOS/PALSAR images using modified synthetic aperture radar offset-tracking procedure” by Ruan et al. addresses SAR’s role. The results indicate that winter glacier motion on the north slope is faster than on the south slope—a result that corresponds well with the local topography. The SAR-based offset tracking is proven to be reliable and robust, making it possible to investigate comprehensive glacier movement and its response to environmental change. “Fluctuations and movements of the Kuksai Glacier, western China, derived from Landsat image sequences” by Yang et al. applies a normalized cross-correlation methodology, indicating that the velocity of the Kuksai glacier is higher in the upper portion and decreases downstream. The study demonstrates that glacial movements can be routinely monitored using Landsat images. “Methodology for geographical data evolution: three-dimensional particle-based real-time snow simulation with remote-sensing data” by Tan et al. addresses a methodology for geographical data evolution from a snow simulation. This computational simulation does not merely generate new data and spatial resolutions at a given time but offers multiscale environmental characteristics of the Earth and presents references for its future.
