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 ⬇️

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!

🌍 After excluding clouds, shade and snow, how much #Sentinel-2 and #Landsat 🛰️ do we really have for 2025?! Continuing our mission and previous research (tinyurl.com/2kbwesbj), we added 2025 to our #GEE App tinyurl.com/322e63p2. Take advantage of this data when planning your #RemoteSensing analysis

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.
 A few things stood out in the data! 📊 ⬇️

The #GreenGrass 2.0 Project aims to enhance the resilience and long-term protection of grassland pasture systems in Germany with smart farming systems. Check out our new StoryMap to see how #remotesensing helps to develop these sustainable pasture management strategies ➡️ arcg.is/1LOKDC1

Observations from 3 #Sentinel2 satellites! Increased revisit frequency. Terrific news! “This configuration will enhance the availability of Sentinel-2 data, with additional Sentinel-2 observations on the same relative orbit, occurring 2 days apart from Sentinel-2B and 1 day apart from Sentinel-2C.”
