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 Phenology and Hydrologic Timing in the Yukon River Basin, AK, USA [PDF]

Remote Sensing, 2021
The Yukon River basin encompasses over 832,000 km2 of boreal Arctic Alaska and northwest Canada, providing a major transportation corridor and multiple natural resources to regional communities. The river seasonal hydrology is defined by a long winter frozen season and a snowmelt-driven spring flood pulse.

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 ...

Complex responses of spring vegetation growth to climate in a moisture-limited alpine meadow. [PDF]

, 2016
Since 2000, the phenology has advanced in some years and at some locations on the Qinghai-Tibetan Plateau, whereas it has been delayed in others. To understand the variations in spring vegetation growth in response to climate, we conducted both regional ...

Soil respiration in a northeastern US temperate forest: a 22‐year synthesis [PDF]

, 2013
To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter‐annual variations in soil respiration (Rs), we analyzed more than 100,000 individual measurements of soil ...

Observational evidence for the convective transport of dust over the central United States [PDF]

, 2016
Bulk aerosol composition and aerosol size distributions measured aboard the DC-8 aircraft during the Deep Convective Clouds and Chemistry Experiment mission in May/June 2012 were used to investigate the transport of mineral dust through nine storms ...
