Global Mountain Snow Cover Extent and Phenology Over 2000-2022 Derived from MODIS Imagery at 500 m

IEEE International Geoscience and Remote Sensing Symposium, 2023
This paper presents data sets derived from MODIS imagery related to snow cover extent and phenology (duration, start and end of the season). The data are based on yearly information and can provide support for understanding the related changes in the ...

A Novel Survival Analysis Model for Quantifying Time-Lagged and Nonlinear Effects of Meteorological Conditions on Snow Phenology

IEEE Transactions on Geoscience and Remote Sensing
Snow phenology is a crucial indicator that captures the dynamic changes in snow cover, which play a significant role in shaping hydrological processes and influencing ecosystem functioning. Recent climate change has affected the temporal dynamics of snow

Snow melt timing acts independently and in conjunction with temperature accumulation to drive subalpine plant phenology

Global Change Biology, 2021
Organisms use environmental cues to align their phenology—the timing of life events—with sets of abiotic and biotic conditions that favor the successful completion of their life cycle.

Observed trends in snow phenology and duration across Romania (1961 to 2020)

2022
<p>Snow cover phenology (onset, melting) and duration are expected to react to temperature trends. Quantification of snow cover changes is an essential step for further climate change impact evaluations given their multiple meteorological, hydrological, ecological, and societal implications.

Disentangling remotely-sensed plant phenology and snow seasonality at northern Europe using MODIS and the plant phenology index

Remote Sensing of Environment, 2017
Land surface phenology is frequently derived from remotely sensed data. However, over regions with seasonal snow cover, remotely-sensed land surface phenology may be dominated by snow seasonality, rather than showing true plant phenology.

Performance and phenology of alpine herbs along a snow‐melting gradient

Ecological Research, 1992
Abstract Responses of plants to the length of the growing season were studied in an alpine snow‐bed by setting five plots along a snow‐melting gradient. Performance and phenology were compared between the plots for five herbaceous species ( Peucedanum multivittatum, Primula cuneifolia, Veronica

Rising Net Shortwave Radiation and Land Surface Temperature Drive Snow Cover Phenology Shifts Across the Mongolian Plateau During the 2000–2022 Hydrological Years

Remote Sensing
Snow cover phenology (SCP) serves as a critical regulator of hydrological cycles and ecosystem stability across the Mongolian Plateau (MP). Despite its importance, the spatiotemporal patterns of SCP and their climatic drivers remain poorly quantified ...

Land surface phenology and greenness in Alpine grasslands driven by seasonal snow and meteorological factors

Science of The Total Environment, 2020
Snow accumulation and melt have multiple impacts on Land Surface Phenology (LSP) and greenness in Alpine grasslands. Our understanding of these impacts and their interactions with meteorological factors are still limited. In this study, we investigate this topic by analyzing LSP dynamics together with potential drivers, using satellite imagery and ...

Impacts of snow cover on vegetation phenology in the arctic from satellite data

Advances in Atmospheric Sciences, 2013
The dynamics of snow cover is considered an essential factor in phenological changes in Arctic tundra and other northern biomes. The Moderate Resolution Imaging Spectroradiometer (MODIS)/Terra satellite data were selected to monitor the spatial and temporal heterogeneity of vegetation phenology and the timing of snow cover in western Arctic Russia (the

Response of vegetation carbon uptake to snow-induced phenological and physiological changes across temperate China

Science of The Total Environment, 2019
Snow cover, which is undergoing significant change along with global climate change, has considerable impacts on the functioning of terrestrial ecosystems. However, how snow cover change affects the vegetation gross primary production (GPP) in temperate regions still requires in-depth exploration.
