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

open access: yesBiogeosciences, 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 ...

Spatiotemporal Variability of Land Surface Phenology in China from 2001–2014

open access: yesRemote Sensing, 2017
Land surface phenology is a highly sensitive and simple indicator of vegetation dynamics and climate change. However, few studies on spatiotemporal distribution patterns and trends in land surface phenology across different climate and vegetation types ...

Large scale climate oscillation impacts on temperature, precipitation and land surface phenology in Central Asia

open access: yesEnvironmental Research Letters, 2018
Central Asia has been rapidly changing in multiple ways over the past few decades. Increases in temperature and likely decreases in precipitation in Central Asia as the result of global climate change are making one of the most arid regions in the world ...

Response of Vegetation Phenology to Climate Change on the Tibetan Plateau Considering Time-Lag and Cumulative Effects

open access: yesRemote Sensing, 2023
The study of the response of vegetation phenology in the Qinghai Tibet Plateau to various climatic variables is paramount to unveiling the reaction of alpine ecosystems to worldwide climate alterations.

Generalization and evaluation of the process-based forest ecosystem model PnET-CN for other biomes [PDF]

open access: yes, 2015
Terrestrial ecosystems play an important role in carbon, water, and nitrogen cycling. Process-based ecosystem models, including PnET-CN, have been widely used to simulate ecosystem processes during the last two decades.

A longer vernal window: The role of winter coldness and snowpack in driving spring thresholds and lags [PDF]

open access: yes, 2017
Climate change is altering the timing and duration of the vernal window, a period that marks the end of winter and the start of the growing season when rapid transitions in ecosystem energy, water, nutrient, and carbon dynamics take place.

A prognostic pollen emissions model for climate models (PECM1.0) [PDF]

open access: yesGeoscientific Model Development, 2017
We develop a prognostic model called Pollen Emissions for Climate Models (PECM) for use within regional and global climate models to simulate pollen counts over the seasonal cycle based on geography, vegetation type, and meteorological parameters ...

Improving Remote Estimation of Vegetation Phenology Using GCOM-C/SGLI Land Surface Reflectance Data

open access: yesRemote Sensing, 2022
Vegetation phenology not only describes the life cycle events of periodic plants during the growing season but also acts as an indicator of biological responses to climate change.
