3D views of Aru Co avalanches from Pléiades stereo imagery

In English snow-ice

Simon Gascoin, 21 octobre 2016

A Pléiades stereo pair has been acquired on 2016-Oct-01 just a few days after the second glacier collapse in the Aru mountains. The panchromatic band has 0.5 m resolution, which allowed us to generate a post-event digital elevation model of the area. From this digital elevation model and the Pléiades 2 m multispectral imagery, Etienne Berthier generated these stunning 3D views of the aftermath…

Preliminary estimates of the volume detached from the glaciers are 66 Mm3 (first, north one) 83 Mm3 (second, southern one).

Impact of the August 12, 2026 eclipse on photovoltaic electricity generation in Spain

Photovoltaic (PV) energy supplies more 20% of Spain’s total electricity, and this share hit a new high in July 2026 (28.3% of the nation’s monthly electricity mix). Some media outlets were concerned about the drop in photovoltaic power generation during the 12-Aug-2026 eclipse. Le Monde explained that « the drop is expected to be particularly pronounced […]
