🛰️ That’s a wrap! The 2nd EnMAP User Workshop brought 3 packed days of talks, posters & hands-on tutorials —exploring how EnMAP data supports research on vegetation, water, soil & atmosphere.

Highlights included hands-on tutorials, lively garden chats, and an exclusive look behind the scenes at @DLR & #ohb

Thanks to all who joined, shared, and inspired! 🌍🚀 #EnMAP #RemoteSensing #EarthObservation #Geography #Hyperspectral #DLR #LMU #CHIME #EnvironmentalScience #research #science #news

ZenodoSupporting Open Science with the CF Metadata Conventions for NetCDFSlides for the presentation given on 11 December 2024 at the AGU Annual Meeting to the session for the AGU Open Science Recognition Prize. Abstact:The CF (Climate and Forecast) Conventions are a community-developed standard that promotes the sharing and automated processing of Earth systems science data in the netCDF data format (and in Zarr/GeoZarr). The CF conventions define metadata that can be used to describe the coordinate systems, data structure, and geophysical meaning and units of each variable. This enables users of data from different sources to decide which quantities are comparable and facilitates building applications with powerful extraction, analysis, and display capabilities. There is a mature and growing ecosystem of FOSS (Free and Open Source Software) and commercial software tools which work with CF. The CF standard has been essential to the success of high-profile internationally-coordinated modeling activities (e.g, the Coupled Model Intercomparison Project, which hosts more than 30 million files and more than 15 petabytes of data, all compliant with CF). CF is widely used by weather, climate, ocean and Earth observation scientists, and is gaining traction among others, such as the biogeochemistry and atmospheric chemistry communities.

HIGHLIGHTS:
• Proposed U-ViT model based on Prithvi GFM for multi-sensor glacial lake mapping.
• Achieved an F1 score of 0.894 on Sentinel-1&2, surpassing CNNs scoring below 0.8.
• Maintains strong performance with 50% less training data, proving efficiency.
• Excels in detecting small lakes (<0.01km²) and handling clouds and complex terrains..."

The Guardian: Tree loss from hurricane leaves Asheville vulnerable to new climate shocks

"The city of Asheville and its surrounding areas have been left vulnerable to floods, fires and extreme heat after Hurricane Helene uprooted thousands of trees that provided shade and protection from storms....

The extent of the tree damage is “extraordinary and humbling”, according to Steve Norman, a research ecologist who conducted the assessment using remote sensing satellites at the Forest Service’s Southern Research Centre."

Lasers reveal 1,000-year-old Indigenous road near Chaco Canyon aligned with winter solstice Researchers have found a sacred road system near Chaco Canyon in New Mexico, revealing the cosmological and spiritual significance of these ancient pathways. A team from Dartmouth College used advanced lidar technology to identify a new road running parallel to an existing one at the Gasco site. Their research points to these roads being built for Indigenous rituals, not for transportation. The paths seem to align with significant celestial events...

I've imagined modern-day Zeppelins some day performing useful tasks, inexpensively though with sedate "deliberate speed." Hauling freight to roadless, runway-less destinations. Loitering over #wildfires dumping water or flame retardant for extended periods. Or festooned with #RemoteSensing instruments, measuring #ecosystem attributes.
