How long does it take until we detect forced signals in global and regional land carbon fluxes?

And can we use dynamical adjustment to reduce the noise and shorten the detection time?

Constraining the time of emergence of anthropogenic signal in the global land carbon sink

Abstract. The global land carbon sink has increased since the preindustrial period, driven by increasing atmospheric CO2 concentration and climate change. However, detecting these anthropogenic signal...

You’ll work on spatiotemporal anomaly detection and use explainable AI to link impacts to weather, soil, and human land use—paving the way for better predictions.

One of 34 funded PhD topics at ScaDS.AI Dresden/Leipzig, spanning ML, time series, ethics, and more.

More details below! Check T9.3!

Introducing #Lexcube4Jupyter
An open-source tool for interactive 3D data cube visualization, seamlessly integrated into scientific workflows. It enables:
✅ Efficient, memory-aware handling of large datasets
✅ Direct integration into Python workflows (e.g., Jupyter Notebooks)

Miguel D. Mahecha @miguelmahecha.bsky.social · Mar 5

We believe that interactive (!) visualisation is key to making high-dimensional Earth system data more accessible, interpretable, and actionable. With this you can achieve
✅ Real-time exploration of model outputs & residuals
✅ Quick data quality checks & anomaly detection

🌿 The dataset focuses on sampling areas impacted by climate extremes, across diverse vegetation types. By prioritizing compound heatwave and drought events, it provides a globally representative and reproducible resource for studying these phenomena!

💡 DeepExtremeCubes is a new database designed to address this gap. 📊 Key features of DeepExtremeCubes: 40,000 globally sampled mini data cubes (2.5 x 2.5 km) with Sentinel-2 L2A for vegetation monitoring, ERA5-Land variables, and ancillary data, including land cover and topography maps.

🌍 Climate extremes, such as compound heatwaves and droughts, are increasing in both frequency and intensity, yet predicting their impacts on terrestrial ecosystems remains a challenge. Machine learning holds promise, but traditional datasets often struggle to represent these rare events effectively.
