Au mois d’août, l’Atacama (Chili) a connu des chutes de neige, un phénomène très inhabituel dans cette région parmi les plus arides du monde. Si le sommet du volcan Licancabur (ici à gauche) est parfois coiffé d’un chapeau blanc, il est fort rare que la neige descende jusqu’à son pied, comme sur cette image satellite capturée le 14 août dernier.
Ce manteau blanc souligne les « pressure ridges » à la surface des coulées de lave visqueuse qui rayonnent depuis le sommet. Ces structures en arc de cercle se forment perpendiculairement à l’écoulement. Leur morphologie rappelle celle des ogives glaciaires, même si le processus de genèse est différent. -

“HIGHLIGHTS:
• ViT-based forest mask, multispectral ensemble LandTrendr and terrain shadow mask.
• District-level RF/XGBoost model training with expert-weighted validation.
• Outperformed GFC and REDD + AI benchmarks in accuracy and F1 performance.
• RF excelled in High Mountains/Himalayas; XGBoost in the lower Mountain regions.
• NBR contributed the most; snow-impacted forest loss uncertainty was observed..."
