Application of a Cloud Removal Algorithm for Snow-Covered Areas from Daily MODIS Imagery over Andes Mountains

Atmosphere, 2022
Snow cover area is dramatically decreasing across the Los Andes Mountains and the most relevant water reservoir under drought conditions. In this sense, monitoring of snow cover is key to analyzing the hydrologic balance in snowmelt-driven basins.

Towards a webcam-based snow cover monitoring network: methodology and evaluation [PDF]

, 2020
Snow cover variability has a significant impact on climate and the environment and is of great socioeconomic importance for the European Alps. Terrestrial photography offers a high potential to monitor snow cover variability, but its application is often

The new indices to describe temporal discontinuity of snow cover on the Qinghai-Tibet Plateau

npj Climate and Atmospheric Science
Snow cover on the Qinghai-Tibet Plateau significantly impacts the climate, hydrology, and ecology of China and East Asia. Current studies mainly use snow cover days to describe its duration, overlooking the snow’s discontinuous nature.

A Comparative Study of Albedo and Microclimatic Characteristics of Snow and Snow Free Covered Underlying Surfaces on the Qinghai-Xizang Plateau

Gaoyuan qixiang
As an important component of the cryosphere， snow cover is an indispensable part of the Earth's system and also an "indicator" of global climate change.The impact of snow cover on the climate system mainly originates from its physical properties such as ...

Spatiotemporal patterns of snow cover retrieved from NOAA-AVHRR LTDR: a case study in the Tibetan Plateau, China

International Journal of Digital Earth, 2017
Snow cover plays an important role in hydrological processes and seasonal water balance. Especially in the Tibetan Plateau (TP), snow cover is an important source of the Yangtze River, Yellow River and Lancang River (SRYYL), which greatly influences ...

Assimilation of snow cover and snow depth into a snow model to estimate snow water equivalent and snowmelt runoff in a Himalayan catchment [PDF]

The Cryosphere, 2017
Snow is an important component of water storage in the Himalayas. Previous snowmelt studies in the Himalayas have predominantly relied on remotely sensed snow cover. However, snow cover data provide no direct information on the actual amount of water

Soil erosion in an avalanche release site (Valle d'Aosta: Italy): towards a winter factor for RUSLE in the Alps [PDF]

, 2014
Soil erosion in Alpine areas is mainly related to extreme topographic and weather conditions. Although different methods of assessing soil erosion exist, the knowledge of erosive forces of the snow cover needs more investigation in order to allow soil ...

Inconsistent response patterns of snow cover duration and snow depth over the Tibetan Plateau to global warming

Advances in Climate Change Research
Snow cover possesses high albedo and thermal insulation properties, greatly influencing climate change and responding rapidly to climatic variation, particularly on the Tibetan Plateau. The region's combination of low latitude and intense solar radiation
