Wrapping up the week with exciting days at Advanced Training Course on Land Remote Sensing.
I contributed to #ESALTC2025 with a session on phenology, in-situ data and accuracy assessment.
Many thanks to @esaearth.esa.int and Aristotle University of Thessaloniki for the excellent organization.

Just finished two packed days attending the AK Fernerkundung, where I had the pleasure of giving a keynote on #EarthObservation in #agriculture.

Grateful for the invitation and a big shout-out to the team at the Uni Bochum for the excellent hosting and insightful discussions.

The potential of Sentinel-1 time series for large-scale assessment of maize and wheat phenology across Germany Monitoring crop phenometrics is crucial for understanding crop conditions and dynamics. Dense time series are needed for accurate information. Recent work has shown that remote sensing data can be ...

Great to see our latest work on #Sentinel-1 based #phenology assessment out! Thanks to Laura Flores Palma for pushing this study forward.

In the new EOAgriTwin research project, researchers are using satellite images, artificial intelligence and modeling to create a digital twin of agricultural landscapes. This replica can provide predictions, for example on crop yields and water consumption.

The Remote Sensing for Agriculture group of @zalf.bsky.social has two open positions:

βœ… PhD: shorturl.at/qqR0o
βœ… PostDoc: shorturl.at/vNpkT

Both positions focus on the multiscale assessment of soil organic carbon (SOC) and tillage practices, using UAV and satellite #EarthObservation data.
