Abstract
Abstract. The effects of forest canopies on snow accumulation and ab-lation processes can be very important for the hydrology of mid- and north-latitude basins. A mass and energy balance model for snow accumulation and ablation processes in forested environments was developed utilizing exten-sive measurements of snow interception and release in a maritime climate mountainous site in Oregon. The model, which was calibrated against one year of weighing lysimeter data and tested at the same site against measure-ments from the next year was able to reproduce the SWE evolution through-out both winters beneath the canopy as well as the nearby clearing, with cor-relations ranging from 0.87 to 0.99. Additionally, the model was evaluated using measurements from the BOREAS field campaign in Canada, without any calibration to test the model robustness in a boreal climate given the effects of micro-meteorology on snow interception. Simulated SWE was rel-atively close to the observations for the forested sites, while simulated snow depth was underestimated during the accumulation period at the forested sites but simulated fairly accurately during ablation.
