A weather chart showing pressure systems and rainfall over the North Atlantic and Western Europe, with coloured precipitation areas and labelled storm tracks.
📣 OpenIFS is now open source!
The move will make it easier to collaborate and generate new ideas.

A world map with red and blue dots. Each dot denotes a water quality measurement station that is included in Caravan-Qual. Red dots are stations with additional streamflow observations. Blue dots are stations without streamflow observations.
Excited to unveil Caravan-Qual! 🌊
We've expanded the Caravan framework to bridge the gap between water quantity and quality.
This new open dataset features: 🔹 ~70M observations 🔹137k stations 🔹 100 constituents 🔹 Linked streamflow, forcing & attributes

Integrating mobile CRNS soil-moisture data into the mHM model greatly boosts its ability to capture spatial and temporal moisture patterns. Forests remain challenging, but results show strong gains and good transferability for better hydrological forecasts.

If you are going to attend EGU 2026 and are interested in statistical ML-based forecasting / nowcasting / post-processing in the geosciences, consider sumitting an abstract to our session NP 5.1, www.egu26.eu/session/55791
⏰ Deadline: January 15, 2026
Soil moisture shapes droughts, floods, and heat extremes, yet is hard to observe from space. Our new paper offers the first structured review of how AI is transforming soil moisture remote sensing, and where hybrid physics-AI approaches can take us next.

Next week, we will mark our 50th anniversary in Reading, UK, following events earlier in the year at our sites in Germany and Italy.
Join us online on 3 December for the Showcase of European capabilities in machine learning and weather forecasting.

So, your forecasts are sharp and reliable, but are they valuable? Our new EMS paper on RUVPY is out - reference implementation of RUV. Honest assessment needs to be tailored to the specific decision. RUV is general enough to model almost any context. Go forth and tinker. doi.org/10.1016/j.en...
EGU Hydrological Sciences is looking for its next Early Career Scientist Rep!

I just published Version 1.6. The main update is that the source data for CAMELS-AUS was upgraded to CAMELS-AUS v2. This means more basins (561 vs 222) and more recent streamflow data (2022 vs 2014).
