Title: Snow melting over the Alps
Backscatter composite of the Alps over a full year: 16 August 2016 – 16 August 2017. Obtained using available images from the Sentinel-1A and -1B satellites, in VH-polarisation, applying a 12-day temporal window with 6-day steps.
With a resolution of 90 m, it shows melting (dark, wet snow backscatter signature) visible first at low elevations in early springtime, then wet snow is left only near the highest peaks.
