Graph Neural Networks Reconstruct Historical Water Storage Data

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel approach using spatio-temporal graph neural networks (MTGNN) to reconstruct historical terrestrial water storage (TWS) data. This deep learning model learns from meteorological forcing data to generate monthly TWS anomalies dating back to 1940, extending the satellite record. The method shows strong performance, achieving high correlations at both grid-cell and basin scales, and reproduces major climate events like El Niño and La Niña. Compared to existing reconstruction techniques, the graph-based model is competitive while requiring fewer predictors and revealing common weaknesses in arid regions across all tested models. AI

IMPACT Enhances historical climate data availability, potentially improving climate modeling and water resource management.

    Reconstructing GRACE Terrestrial Water Storage with Spatio-Temporal Graph Neural Networks: An Application to South America

    arXiv:2606.23833v1 Announce Type: new Abstract: Terrestrial water storage (TWS) integrates snow, soil moisture, surface water, and groundwater and is a key indicator of how climate variability and human activity reshape the global water cycle. The GRACE and GRACE-FO satellite mis…
