Snow depth measurements from Arctic tundra and boreal forest collected during NASA SnowEx Alaska campaign [PDF]

open access: yesScientific Data
Boreal forest and Arctic tundra environments collectively hold the largest percentage of global terrestrial seasonal snow cover. Тhe in-situ snow measurement network is sparse and costly in these remote northern regions. Here, we complement existing snow

Reconstruction of Snow Depth Data at Moderate Spatial Resolution (1 km) from Remotely Sensed Snow Data and Multiple Optimized Environmental Factors: A Case Study over the Qinghai-Tibetan Plateau

open access: yesRemote Sensing, 2021
Snow depth distribution in the Qinghai-Tibetan plateau is important for atmospheric circulation and surface water resources. In-situ observations at meteorological stations and remote observation by passive microwave remote sensing technique are two main

Snow Depth Fusion Based on Machine Learning Methods for the Northern Hemisphere

open access: yesRemote Sensing, 2021
In this study, a machine learning algorithm was introduced to fuse gridded snow depth datasets. The input variables of the machine learning method included geolocation (latitude and longitude), topographic data (elevation), gridded snow depth datasets ...

Snow Depth Inversion in Forest Areas from Sentinel-1 Data Based on Phase Deviation Correction

open access: yesRemote Sensing, 2022
At present, snow depth inversion based on active microwave remote sensing is concerned essentially with areas having a relatively simple underlying surface.

Mapping snow depth on Canadian sub-arctic lakes using ground-penetrating radar [PDF]

open access: yesThe Cryosphere, 2023
Ice thickness across lake ice is mainly influenced by the presence of snow and its distribution, which affects the rate of lake ice growth. The distribution of snow depth over lake ice varies due to wind redistribution and snowpack metamorphism ...

Snowpack Distribution Using Topographical, Climatological and Winter Season Index Inputs

open access: yesAtmosphere, 2021
A majority of the annual precipitation in many mountains falls as snow, and obtaining accurate estimates of the amount of water stored within the snowpack is important for water supply forecasting. Mountain topography can produce complex patterns of snow

Modeling Snow Depth and Snow Water Equivalent Distribution and Variation Characteristics in the Irtysh River Basin, China

open access: yesApplied Sciences, 2021
Accurate simulation of snow cover process is of great significance to the study of climate change and the water cycle. In our study, the China Meteorological Forcing Dataset (CMFD) and ERA-Interim were used as driving data to simulate the dynamic changes

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.

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.

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.
