Spatiotemporal variations of alpine climate, snow cover and phenology

2017 9th International Workshop on the Analysis of Multitemporal Remote Sensing Images (MultiTemp), 2017
Understanding the relationships between vegetation phenology and its seasonal drivers under varying site conditions is of high interest in mountain areas, since alpine ecosystems are assumed to be particularly sensitive to climatic changes. Through the joint analysis of NDVI, snow metrics, and climate data at 250 m and 2 km spatial resolution ...

Snow goose migration phenology is related to extratropical storm climate

International Journal of Biometeorology, 1984
The phenologies of autumn and spring migrations by greater snow geese (Anser caerulescens atlantica) are shown to be statistically independent. Spring and fall migration phenologies are demonstrated to be significantly related to synoptic scale atmospheric circulation systems (extratropical storms) rather than a factor such as temperature.

Ground observed climatology and trend in snow cover phenology across China with consideration of snow-free breaks

Climate Dynamics, 2020
Accurate understanding of snow cover phenology and its changes is important to hydrological processes and climate system. Having recognized the potential uncertainties in remote sensing snow cover products, we used daily snow depth observations from 514 meteorological stations across China to investigate the spatiotemporal variations in snow cover ...

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
