Soil moisture is a small signal with a large influence: it shapes crop growth, drought development, flood risk, and the exchange of water and heat between land and atmosphere. Yet this hidden variable remains difficult to track continuously at a global scale. A new study shows how reflected navigation signals from space can be combined to map soil moisture more consistently across diverse landscapes. By integrating observations from Tianmu-1 and Fengyun-3, the researchers developed an attention-Read More
