Melt Detection and Estimation in Greenland Using Tandem QuikSCAT and SeaWinds Scatterometers
… scatterometers are used to classify the melt state and estimate melt severity in Greenland. Backscatter measurements are organized into high temporal and high spatial resolution images created using the Scatterometer Image Reconstruction (SIR) algorithm and a new temporal data …

A New Method for Melt Detection on Antarctic Ice-Shelves and Scatterometer Calibration Verification
… (SSM/I) are used to determine periods of surface melt and freeze in the Antarctic ice-shelves. The normalized radar backscatter (sigma-0) and backscatter polarization ratio (PR) are used in the maximum likelihood estimation of the ice-state. This method is used to infer the daily ice-surface …

Snowmelt Detection on Alpine Glaciers using Synthetic Aperture Radar Time Series
… of sensitive aquatic alpine ecosystems. As snowmelt onsets sooner, lasts longer, and snowfields retreat due to increases in global temperature, the hydrologic dynamics of catchments draining HKH threaten to change the availability of surface freshwater resources for nearly one fifth of the …

Microwave Remote Sensing of the Greenland Ice Sheet: Models and Applications
… the microwave signature of the snow surface, (3) detection of snow melt, and (4) classification of snow melt. The results are applicable for identifying geophysical properties of the snow surface and monitoring changes on the ice sheet in relation to melt duration/extent, accumulation, and wind …
