A shift toward more severe and persistent compound hot–dry extremes across the Mongolian Plateau

Climate extremes have become increasingly frequent and severe worldwide under global warming. Among them, compound hot–dry events pose particularly acute threats to ecosystems, water resources, and agricultural systems, often producing greater impacts than heatwaves or droughts occurring alone. Using the ERA5-Land...

Mathematical Simulation‐Based Evaluation of Measurement Error Impacts on Topographic Change Detection

Topographic change detection is widely applied in fields such as geological hazard early warning, environmental monitoring, and geographic process analysis. However, measurement errors—such as random and systematic errors—are inevitable during the acquisition of topographic data, and their propagation and accumulatio...
