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.

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.

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.

Global-Scale Associations of Vegetation Phenology with Rainfall and Temperature at a High Spatio-Temporal Resolution

open access: yesRemote Sensing, 2014
Phenology response to climatic variables is a vital indicator for understanding changes in biosphere processes as related to possible climate change. We investigated global phenology relationships to precipitation and land surface temperature (LST) at ...

Improving vegetation phenological parameterization of a land surface model [PDF]

open access: yes, 2016
Abstract. The growing degree day (GDD) model and the growing season index (GSI) model are two common approaches used in various land surface models (LSMs) for simulating phenophases. The capacity of these two models for simulating phenolphases was evaluated by coupling them to a LSM (DLM: Dynamic Land Model) and validated by observation data from the ...

Assessing satellite-derived land product quality for earth system science applications: results from the ceos lpv sub-group [PDF]

open access: yes, 2011
The value of satellite derived land products for science applications and research is dependent upon the known accuracy of the data. CEOS (Committee on Earth Observation Satellites), the space arm of the Group on Earth Observations (GEO), plays a key ...

Development of a global annual land surface phenology dataset for 1982–2018 from the AVHRR data by implementing multiple phenology retrieving methods

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
The land surface phenology (LSP) associated with vegetation dynamics plays an important role in influencing the land surface processes and land–atmosphere interactions.

Near-surface remote sensing of spatial and temporal variation in canopy phenology [PDF]

open access: yes, 2009
There is a need to document how plant phenology is responding to global change factors, particularly warming trends. “Near-surface” remote sensing, using radiometric instruments or imaging sensors, has great potential to improve phenological monitoring ...

Land surface phenology as an indicator of biodiversity patterns [PDF]

open access: yesEcological Indicators, 2016
Abstract With the rapid decline in biodiversity worldwide it is imperative to develop procedures for assessing changes in biodiversity across space. The synoptic view provided by imaging remote sensors constitutes a suitable approach for analyzing biodiversity from local to regional scales.
