Assessment of the Daily Cloud-Free MODIS Snow-Cover Product for Monitoring the Snow-Cover Phenology over the Qinghai-Tibetan Plateau [PDF]

Remote Sensing, 2017
Snow cover plays a crucial role in surface hydrology and energy balance, especially in the Qinghai-Tibetan Plateau (QTP). This study used 12 years (2000–2011) of ground-observed snow depth at 87 meteorological stations to assess and verify the accuracy ...

Spatiotemporal variation characteristics and influencing factors of snow density in the High Mountain Asia from 1960 to 2023. [PDF]

PLoS ONE
Under the context of climate change, significant variations in snow density have been observed in the High Mountain Asia, however, its spatiotemporal patterns and underlying drivers remain incompletely understood.

Phenological Responses to Snow Seasonality in the Qilian Mountains Is a Function of Both Elevation and Vegetation Types

Remote Sensing, 2022
In high-elevation mountains, seasonal snow cover affects land surface phenology and the functioning of the ecosystem. However, studies regarding the long-term effects of snow cover on phenological changes for high mountains are still limited.

Characterizing ecosystem phenological diversity and its macroecology with snow cover phenology [PDF]

Scientific Reports, 2019
AbstractOne critical challenge of exploring flora phenology is on characterizing ecosystem phenological diversity (EPD), and thus how EPD’s performance is influenced by climate changes has also been an open macro-ecological question. To fill these two gaps, we proposed an innovative method for reflecting EPD, by taking the advantage of the often ...

Variability in snow cover phenology in China from 1952 to 2010 [PDF]

Hydrology and Earth System Sciences, 2016
Abstract. Daily snow observation data from 672 stations in China, particularly the 296 stations with over 10 mean snow cover days (SCDs) in a year during the period of 1952–2010, are used in this study. We first examine spatiotemporal variations and trends of SCDs, snow cover onset date (SCOD), and snow cover end date (SCED).

Altitude-dependent influence of snow cover on alpine land surface phenology [PDF]

Journal of Geophysical Research: Biogeosciences, 2017
AbstractSnow cover impacts alpine land surface phenology in various ways, but our knowledge about the effect of snow cover on alpine land surface phenology is still limited. We studied this relationship in the European Alps using satellite‐derived metrics of snow cover phenology (SCP), namely, first snow fall, last snow day, and snow cover duration ...

Snow and vegetation seasonality influence seasonal trends of leaf nitrogen and biomass in Arctic tundra

Ecosphere, 2023
Climate change, including both increasing temperatures and changing snow regimes, is progressing rapidly in the Arctic, leading to changes in plant phenology and in the seasonal patterns of plant properties, such as tissue nitrogen (N) content and ...

Evaluation of E3SM land model snow simulations over the western United States [PDF]

The Cryosphere, 2023
Seasonal snow has crucial impacts on climate, ecosystems, and humans, but it is vulnerable to global warming. The land component (ELM) of the Energy Exascale Earth System Model (E3SM) mechanistically simulates snow processes from accumulation, canopy ...

Declining snow cover may affect spring phenological trend on the Tibetan Plateau [PDF]

Proceedings of the National Academy of Sciences, 2013
Zhang et al. (1) report that the Tibetan Plateau experienced a continuous advancing start of green-up date (SOS) from 1982 to 2011 based on the merged Global Inventory Modeling and Mapping Studies (GIMMS)-based with Moderate Resolution Imaging Spectroradiometer (MODIS) [Systeme Pour l’Observation de la Terre vegetation (SPOT-VGT)]-based SOSs.

Impact of Snowpack on the Land Surface Phenology in the Tianshan Mountains, Central Asia

Remote Sensing, 2022
The accumulation and ablation processes of seasonal snow significantly affect the land surface phenology in a mountainous ecosystem. However, the ability of snow to regulate the alpine land surface phenology in the arid regions is not well described in ...
