Editorial statement
This paper presents a global, high-resolution dataset of snowmelt runoff onset spanning a decade of Sentinel-1 observations. Its combination of global coverage, fine spatial resolution, comprehensive documentation, and broad applicability makes it a valuable resource for hydrology, cryosphere research, and water resource management.

Short summary
Meltwater from seasonal snow sustains over a billion people globally, making the timing of snowmelt runoff onset a critical hydrological parameter. We used satellite radar images, which can detect liquid water in snowpack regardless of cloud cover, to create a global dataset of snowmelt runoff onset timing from 2015 to 2024 at 80 m resolution. The dataset shows close agreement with a network of ground-based snow sensors, and can support water resource management in snow-dominated watersheds.
