Short summary
We developed a new model to estimate snow depth using radar satellite data. By correcting for how the viewing angle affects signal reflection, we reduced errors by nearly 40 %. Tested in the Alps and Norway, the method improves fine-scale snow monitoring, supporting avalanche forecasting and water management.
