Generation of daily high-spatial resolution snow depth maps from in-situ measurement and time-lapse photographs

open access: yesCuadernos de Investigación Geográfica, 2020
Acquiring information on snow depth distribution at high spatial and temporal resolution in mountain areas is time consuming and generally these acquisitions are subjected to meteorological constrains.

Accuracy assessment of late winter snow depth mapping for tundra environments using Structure-from-Motion photogrammetry

open access: yesArctic Science, 2021
Arctic tundra environments are characterized by a spatially heterogeneous end-of-winter snow depth resulting from wind transport and deposition. Traditional methods for measuring snow depth do not accurately capture such heterogeneity at catchment scales.

Brief communication: Comparison of in situ ephemeral snow depth measurements over a mixed-use temperate forest landscape [PDF]

open access: yesThe Cryosphere, 2023
The accuracy and precision of snow depth measurements depend on the measuring device and the conditions of the site and snowpack in which it is being used.

Unmanned Aerial Vehicle-Based Structure from Motion Technique for Precise Snow Depth Retrieval—Implication for Optimal Ground Control Point Deployment Strategy

open access: yesRemote Sensing, 2023
Unmanned aerial vehicle (UAV)-based snow depth is mapped as the difference between snow-on and snow-off digital surface models (DSMs), which are derived using the structure from motion (SfM) technique with ground control points (GCPs).

An Approaching on Estimating of Snow Depth and Snow Water Equivalent.

open access: yesAir and Water Components of the Environment Conference, 2020
Snow water equivalent (SWE) and snow depth (SD) is estimating using Snow 17 model for several meteorological mountain stations from Romania. The model uses air temperature as the sole index to determine the energy exchange across the snow-air interface.
