Climate change, phenology, and phenological control of vegetation feedbacks to the climate system

Agricultural and Forest Meteorology, 2013
a b s t r a c t Vegetation phenology is highly sensitive to climate change. Phenology also controls many feedbacks of vegetation to the climate system by influencing the seasonality of albedo, surface roughness length, canopy conductance, and fluxes of water, energy, CO2 and biogenic volatile organic compounds.

Variations in satellite‐derived phenology in China's temperate vegetation

Global Change Biology, 2006
AbstractThe relationship between vegetation phenology and climate is a crucial topic in global change research because it indicates dynamic responses of terrestrial ecosystems to climate changes. In this study, we investigate the possible impact of recent climate changes on growing season duration in the temperate vegetation of China, using the ...

Photoperiod Explains the Asynchronization Between Vegetation Carbon Phenology and Vegetation Greenness Phenology

Journal of Geophysical Research: Biogeosciences, 2020
AbstractVegetation carbon phenology is a key indicator of vegetation actual photosynthesis activity and regulates terrestrial ecosystem carbon balance. A comprehensive understanding of the structural difference of carbon phenology and greenness phenology is still lacking.

Climate Change and Vegetation Phenology

2020
The rate at which climate change is influencing the living organisms and ecosystem is considered as a major threat to sustaining the resources that are required for the human survival in the future. Environmental impacts on the life stages and functioning of organisms have been a major area of study over the last century. The information available from

Template phenology for vegetation models

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
To assist the representation of phenology in vegetation models we created several templates of phenology-driver relations by characterizing the annual phase differences between phenology and two phenology drivers. We did this using the results of a cross spectral analysis of MODIS EVI with radiation (CPTEC) and with precipitation (TRMM).

Spring phenology alters vegetation drought recovery

Nature Climate Change, 2023
A changing climate is altering vegetation phenology and likely impacts drought frequency and severity. Changes in vegetation phenology have some unexpected consequences on the trajectories of drought recovery.

Phenology of Vegetation Photosynthesis

2003
In this chapter, we expanded the traditional research area of plant phenology by characterizing plant community growth activities from vegetation photosynthesis. We introduced a systematic approach to objectively determine the various stages in the seasonal march of vegetation photosynthesis.

Evaluation of Urban Vegetation Phenology Using 250 m MODIS Vegetation Indices

Photogrammetric Engineering & Remote Sensing, 2022
The dynamics of urban vegetation phenology play an important role in influencing human activities. Previous studies have shown high-resolution remote sensing as a tool for urban vegetation mapping, but the low temporal resolution of these data limits their use for phenological modeling.

Vegetation Phenology in Global Change Studies

2003
Global change, encompassing natural and anthropogenic changes to the Earth system at sub-annual to geologic time scales, has strong interactions with vegetation phenology. In this chapter we will refer to global change as alterations to the Earth system that are certainly or probably influenced by human activity, primarily since the industrial ...

Vegetation Phenology in Global Change Studies

2013
Changes in the character of the vegetated land surface are frequently expressed in terms of temporal trends in the Normalized Difference Vegetation Index (NDVI) retrieved from spaceborne sensors. In the past these change studies were typically based upon AVHRR data.
