New preprint for the #DeepFeatures project:
Why choose between spatial detail and temporal fidelity in #EO data?
We developed a #ContextAware #multimodalAI framework that unifies satellite data ( #Sentinel1 & #Sentinel2) into a single, high-resolution view of land surface properties.

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?

🌍 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.

Recently published: deforestation leads to an increase in albedo, but this cooling effect of climate is by almost half compensated for by decreases in cloudiness www.nature.com/articles/s41...
Decreased cloud cover partially offsets the cooling effects of surface albedo change due to deforestation - Nature Communications
This study shows that deforestation locally reduces global low-level and tropical high-level clouds, with the resulting warming partially counteracting the cooling of increased surface albedo.
