Spatiotemporal Characteristics and Heterogeneity of Vegetation Phenology in the Yangtze River Delta

open access: yesRemote Sensing, 2022
Vegetation phenology and its spatiotemporal driving factors are essential to reflect global climate change, the surface carbon cycle and regional ecology, and further quantitative studies on spatiotemporal heterogeneity and its two-way driving are needed.

Global Assessment of Cumulative and Time-Lag Effects of Drought on Land Surface Phenology

open access: yesGIScience & Remote Sensing, 2022
Increased frequency and intensity of droughts under climate change will have a significant impact on land surface phenology, however, the drought-phenology interactions that are associated with complex temporal effects are not well understood. This study

Implementation of a new crop phenology and irrigation scheme in the ISBA land surface model using SURFEX_v8.1 [PDF]

open access: yesGeoscientific Model Development, 2022
With an increase in the number of natural processes represented, global land surface models (LSMs) have become more and more accurate in representing natural terrestrial ecosystems.

Comparisons of numerical phenology models and machine learning methods on predicting the spring onset of natural vegetation across the Northern Hemisphere

open access: yesEcological Indicators, 2021
The timing of vegetation spring onset is largely influenced by climate factors, making it sensitive to climate variation. Robust models that predict vegetation spring onset via the climate forcing data are needed in the land surface models for ...

Mapping Crop Cycles in China Using MODIS-EVI Time Series [PDF]

open access: yes, 2014
As the Earth’s population continues to grow and demand for food increases, the need for improved and timely information related to the properties and dynamics of global agricultural systems is becoming increasingly important.

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

open access: yesRemote 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 ...

Detecting and predicting spatial and interannual patterns of temperate forest springtime phenology in the eastern U.S. [PDF]

open access: yes, 2002
We performed a diagnostic analysis of AVHRR-NDVI and gridded, temperature data for the deciduous forests of the eastern U.S., calibrating temperature accumulation model with satellite data for 1982–1993.

Global land surface phenology trends from GIMMS database [PDF]

open access: yesInternational Journal of Remote Sensing, 2009
A double logistic function has been used to describe global inventory mapping and monitoring studies (GIMMS) normalized difference vegetation index (NDVI) yearly evolution for the 1981 to 2003 period, in order to estimate land surface phenology parameter.

Modelling fire occurrence at regional scale. Does vegetation phenology matter? [PDF]

open access: yes, 2015
Through its influence on biomass production, climate controls fuel availability affecting at the same time fuel moisture and flammability, which are the main determinants for fire ignition and propagation.

War, Drought, and Phenology: Changes in the Land Surface Phenology of Afghanistan Since 1982 [PDF]

open access: yes2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
War and resulting institutional changes can be important drivers of land use and land cover change. We explore how war, its consequences, and drought have affected the land surface phenology (LSP) of Afghanistan. Afghanistan offers a unique case of a semi-arid country with multiple institutional changes during the past two decades.
