Simone Stuenzi, @smstuenzi.bsky.social, postdoc at the EOLab, and colleagues from @awi.de, @vuamsterdam.bsky.social and @uio.no, use process-based permafrost modeling, satellite time-series, and field data to study canopy-ground thermal dynamics, addressing a blind spot in Earth system models.

How do trees keep permafrost frozen? Research by @smstuenzi.bsky.social shows forest cover cools the ground surface and can reduce active layer thickness by up to 60 percent compared to open ground. The forest canopy regulates ground temperature through complex, multi-directional processes.

Beneath the tundra and forests of the Arctic lies permafrost: ground frozen year-round. @smstuenzi.bsky.social's research focuses on how boreal forests and permafrost interact, and what happens when that relationship breaks down. Read all about it in this new StoryMap! arcg.is/18Wa810

A new study by @jalsleben.bsky.social et al. introduces a national approach to map tree dieback across Germany using Sentinel-2 time series. Instead of just measuring greenness, it directly quantifies non-photosynthetic vegetation at a sub-pixel scale. Let's have a closer look ⬇️

Grassland age is a critical parameter influencing carbon sequestration potential, biodiversity support, and ecosystem resilience. 
A new study published in Remote Sensing of Environment presents a national-scale framework to estimate grassland age across Germany using satellite time series:

"Detectives from Space - Discovering Geography from Above": We were delighted to present the fundamentals and possibilities of remote sensing at this year's Long Night of Science at HU Berlin's Campus Adlershof. A great opportunity to engage with and inspire potential future students! #LNDW2026

The Geography Department of the HU Berlin is part of The Long Night of Science 2026! Tomorrow, June 6th, 5-10pm, Alfred-Rühl-Haus, Rudower Chaussee 16. The Earth Observation Lab, @biogeoberlin.bsky.social and many more will await you with exhibitions, games, lectures and hands-on experiments!

EARSeL VP Jean-Christophe Schyns congratulates @lasseharkort.bsky.social for winning the Young Scientist Award at the Imaging Spectroscopy SIG. Lasse's presentation "Capturing the Pulse of the Dry Season" showed how EnMAP time series can disentangle different NPV types from space. Congrats, Lasse!

EOLab’s @jakimowb.bsky.social , @lasseharkort.bsky.social and Shawn Schneidereit participated in the 14th EARSeL Workshop on Imaging Spectroscopy, hosted by Aalto University (@aalto.fi) in Helsinki, presenting their recent research utilizing EnMAP hyperspectral time series and the EnMAP-Box.

Smallholder farming systems are notoriously difficult to map from space. Landscapes are fragmented and global maps often disagree, yet data on where farming actually happens is fundamental to designing effective land use and sustainability policies.
