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

Geoscientific 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.

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

Ecological 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.

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

Ecological 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 ...

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

, 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 ...

Impacts of Thermal Time on Land Surface Phenology in Urban Areas [PDF]

Remote Sensing, 2017
Urban areas alter local atmospheric conditions by modifying surface albedo and consequently the surface radiation and energy balances, releasing waste heat from anthropogenic uses, and increasing atmospheric aerosols, all of which combine to increase temperatures in cities, especially overnight, compared with surrounding rural areas, resulting in a ...

The blsp R package with a Bayesian land surface phenology model

, 2022
This software is an R package providing the Bayesian land surface phenology (BLSP) model that quantifies long-term annual land surface phenology from temporally sparse optical remote sensing time series (originally developed for 30 m Landsat time series).

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

Remote 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 ...

Estimating and Monitoring Land Surface Phenology in Rangelands: A Review of Progress and Challenges [PDF]

Remote Sensing, 2021
Land surface phenology (LSP) has been extensively explored from global archives of satellite observations to track and monitor the seasonality of rangeland ecosystems in response to climate change. Long term monitoring of LSP provides large potential for the evaluation of interactions and feedbacks between climate and vegetation.

Land surface phenological response to decadal climate variability across Australia using satellite remote sensing [PDF]

Biogeosciences, 2014
Land surface phenological cycles of vegetation greening and browning are influenced by variability in climatic forcing. Quantitative spatial information on phenological cycles and their variability is important for agricultural applications, wildfire ...

Alternative methods to predict actual evapotranspiration illustrate the importance of accounting for phenology – Part 2: The event driven phenology model [PDF]

Biogeosciences, 2012
Evapotranspiration (ET) flux constitutes a major component of both the water and energy balances at the land surface. Among the many factors that control evapotranspiration, phenology poses a major source of uncertainty in attempts to predict ET ...
