- The high-mountain Third Pole (TP) in Asia is undergoing rapid warming, profoundly impacting river discharge. Changes in precipitation and the degradation of glaciers and permafrost exert a substantial impact on TP rivers, affecting millions downstream. Nevertheless, conventional estimation methods that rely on in -situ observations and models face considerable challenges due to inconsistent data quality and availability, complex terrain, and difficulty in representing hydrological processes. Here, we harnessed the power of high-resolution (3 m) Dove/ PlanetScope satellite images to meticulously measure river width and propose a novel formula for estimating discharge. This approach facilitates a coherent assessment of discharge at various river section shapes. Its efficacy is demonstrated through applying to thirteen high-mountain TP rivers, revealing an estimated total mountain discharge of 3786 billion m 3 during 2017 - 2021, equaling water from approximately 167 Great Lakes. These findings have immediate implications for integrated water resources management at the poorly-gauged transboundary basins of Asia.
