Satellite altimetry reveals heterogeneity in global flood peak timing and its shifts

Flood peak timing (FloPT) is a key indicator of hydrological responses to climate change. Yet global FloPT assessments is limited by sparse and uneven in-situ discharge observations. Here, we demonstrated the capability of satellite altimetry to estimate FloPT worldwide and prese...

Improved estimation of lake storage variation via DEM reconstruction integrating elevation and morphological constraints

High-quality Digital Elevation Models (DEMs) are essential for accurately estimating lake storage variations, but the high cost of in-situ measurements limits their large-scale application. Reconstructing DEMs from remote sensing-derived lake contours is a promising low-cost alte...
