Mountain glaciers analyzed by remote sensing

Methods

Ice velocities

Study of SAR radiometric changes: Leclerc and REACTIV methods

Study of snow cover: Nagler Method, Lievens Method and NDSI

The Guil basin

Karakoram

Mask obtained by the Leclerc Method to identify rapid backscattering changes
The REACTIV_season algorithm, applied here on the Karakoram chain, allows to quickly identify particular change phenomena, and the years in which the main change is recorded.

Glacier Speed

Velocities computed over the Kyagar glacier.
Surface velocities for Rimo glacier on the left and Miar glacier on the right. The datasets are from RETREAT on the top and ITS_LIVE at the bottom.

Snow Cover Analysis

Velocity magnitude over a point on the Rimo glacier based on ITS_LIVE dataset

Alaska, Malaspina Glacier

REACTIV_by_season applied to Alaska, reveals strong variations on the Agassiz Lake
REACTIV_season applied to Malaspina Glacier
