Small and Medium‐Sized Inland Waterbodies: Water Volume Predictions and Flood Implications

open access: yesWater Resources Research, Volume 62, Issue 1, January 2026.
Abstract Small (<10 ha) and medium (10–100 ha) inland waterbodies are crucial for water storage and flood regulation, necessitating an improved understanding of their water volume. Traditional water volume measurement methods, modeling techniques, and advanced altimetry missions struggle to capture the non‐linear volume changes in these waterbodies ...

Spaceborne Canopy Height Products Should Be Complemented With Airborne Laser Scanning Data: Toward a European Canopy Height Model

open access: yesEarth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Measuring and mapping vegetation structure is essential for understanding the functioning of terrestrial ecosystems and for informing environmental policies. Recent years have seen a growing demand for high‐resolution data on vegetation structure, driving their prediction at fine resolutions (1–30 m) at state, continental, and global spatial ...

On Optimal Parameterization for Mascon Solution of Surface Mass Changes From GRACE(‐FO) Satellite Gravimetry

open access: yesEarth and Space Science, Volume 13, Issue 1, January 2026.
Abstract The Gravity Recovery and Climate Experiment (GRACE) and its successor, GRACE‐Follow On, play an important role in monitoring mass transport across the Earth. Compared to spherical harmonic solutions, mass concentration (mascon) solutions offer less signal leakage and a “higher” spatial resolution. How the shapes, sizes, and positions of mascon
