From: Snow depth variability in the Northern Hemisphere mountains observed from space
Backscatter and snow depth time series at 4 sites. The left column shows the co-polarized backscatter (σ 0vv; in dB), the middle column the cross-polarized backscatter (σ 0vh; in dB), and the right column the cross-polarization ratio (σ 0vh/σ 0vv; in dB). Snow cover presence (dimensionless) from IMS is shown in gray. Site details, including mountain range and latitude/longitude/elevation: a Omineca Mountains, British Columbia, Canada (57.53°N/−126.73°E/1331 m), b Absaroka Range, Wyoming, USA (45.22°N/−110.24°E/2697 m), c San Juan Mountains, Colorado, USA (37.71°N/−107.51°E/3535 m), d European Alps, Austria (46.87°N/10.71°E/2464 m). The ranges of the backscatter (dB) and snow depth (m) measurements have been adjusted between sites to improve visualization
