Excited to announce Groundsource - an open-source dataset of historic flood events! This has easily been one of the coolest projects I've worked on recently! Thread 🧵 for details and all relevant links. 1/n

A worldmap of the spatial distribution of extracted flood events in the Groundsource dataset. The map displays the total number of flood events extracted by the LLM-based pipeline aggregated per grid cell. The data are visualized using a Robinson projection, with event counts represented by a logarithmic color scale. Red points indicate the spatial centroids of reference flood events from the GDACS database.

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 Links in 🧵

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.

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. www.frontiersin.org/journals/wat...

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. doi.org/10.1016/j.ja... #AI4SoilMoisture #EO

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...
