Short summary
Predicting hydrological runoff in Arctic permafrost regions is difficult due to limited observations and complex terrain. We used a detailed physics-based model simulations to improve runoff estimates in a Earth system land model. Our method improved runoff accuracy and worked well across two different Arctic regions. This helps make runoff parameterization schemes more reliable for understanding water flow in permafrost areas under a changing climate.
