Remote Sensing Phenology of Antarctic Green and Red Snow Algae Using WorldView Satellites [PDF]

Frontiers in Plant Science, 2021
Snow algae are an important group of terrestrial photosynthetic organisms in Antarctica, where they mostly grow in low lying coastal snow fields. Reliable observations of Antarctic snow algae are difficult owing to the transient nature of their blooms and the logistics involved to travel and work there.

Relationship between vegetation phenology and snow cover changes during 2001–2018 in the Qilian Mountains

Ecological Indicators, 2021
Vegetation phenology has a profound impact on soil and water conservation and biogeochemical cycles, while its relationship with snow parameters has not been well addressed for parts of the Qinghai-Tibet Plateau (QTP).

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 ...

Relative Influence of Timing and Accumulation of Snow on Alpine Land Surface Phenology [PDF]

Journal of Geophysical Research: Biogeosciences, 2018
AbstractTiming and accumulation of snow are among the most important phenomena influencing land surface phenology in mountainous ecosystems. However, our knowledge on their influence on alpine land surface phenology is still limited, and much remains unclear as to which snow metrics are most relevant for studying this interaction.

Characteristics of Snow Depth and Snow Phenology in the High Latitudes and High Altitudes of the Northern Hemisphere from 1988 to 2018

SSRN Electronic Journal, 2022
Snow cover is an important part of the Earth’s surface and its changes affect local and even global climates due to the high albedo and heat insulation. However, it is difficult to directly compare the results of previous studies on changes in snow cover in the Northern Hemisphere mainland (NH) due to the use of different datasets, research methods, or

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 ...

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 ...

Snow Cover Phenology Change and Response to Climate in China during 2000–2020

Remote Sensing, 2022
Snow cover phenology (SCP) is critical to the climate system. China has the most comprehensive snow cover distribution in the middle and low latitudes and has shown dramatic changes over the past few decades. However, the spatiotemporal characteristics of SCP parameters and their sensitivity to meteorological factors (temperature and precipitation ...
