Stationary precipitation measurements are frequently affected by undercatch errors, which are particularly pronounced in cold and alpine regions with strong winds. Since gridded precipitation products used in land surface modeling are often derived from spatial interpolation of meteorological station data, these measurement …

Monitoring and forecasting mountainous runoff is essential, as snowmelt provides vital freshwater resources while also posing flood and drought risks to downstream regions. However, spatiotemporal modeling of the high-alpine snowpack remains challenging, due to shortcomings in their process-based descriptions and substantial deficits …

Abstract Hydroclimatic extremes such as droughts cause significant anomalies in the global carbon cycle, e.g. via reductions in ecosystem gross primary production (GPP), and hamper the storage capacity of the terrestrial carbon sink. At the same time, across snow covered ecosystems, plant-water …

Abstract:Knowledge of spatio-temporal snow storage is crucial to understand snow-hydrological dynamics in complex, high alpine environments. Due to the low cost and fast deployability, photogrammetry in combination with commercial aerial photography UAVs has become a viable method for capturing high-resolution snowpack information. …

Snow depth (SD) estimations are very valuable in particular for snow-hydrological modelling, water resource management, ecological studies, and natural hazard assessment such as avalanche forecasting. In statistical SD models, snow-covered area is often used as a source of information. This study explores …

Monitoring snow water resources is crucial to understand the dynamics of snow-fed mountain rivers. Still, in harsh and remote environments like mountain regions using conventional measurement techniques remains particularly challenging. Cosmic-Ray Neutron Sensing (CRNS) constitutes an emerging method for autonomous and non-invasive …

Estimating the amount of snow, its evolution and spatiotemporal distribution in complex high-alpine terrain is currently considered as one of the most important challenges in alpine hydrology and water resources management. This is predominantly caused by the lack of accurate information on …

Abstract The lack of accurate information on the spatiotemporal variations of snow water equivalent (SWE) in mountain catchments remains a key problem in snow hydrology and water resources management. This is partly because there is no sensor to measure SWE beyond local …
