Harmonized European long-term climate data for assessing the effect of changing temporal variability on land-atmosphere CO2 fluxes
Temporal variability of meteorological variables and extreme weather events is projected to increase in many regions of the world during the next century. Artificial experiments using process-oriented terrestrial ecosystem ...
Few extreme events dominate global interannual variability in gross primary production
Understanding the impacts of climate extremes on the carbon cycle is important for quantifying the carbon-cycle climate feedback and highly relevant to climate change assessments. Climate extremes and fires can have severe ...
Uncertainty analysis of gross primary production upscaling using Random Forests, remote sensing and eddy covariance data
The accurate quantification of carbon fluxes at continental spatial scale is important for future policy decisions in the context of global climate change. However, many elements contribute to the uncertainty of such ...
On the relationship between ecosystem-scale hyperspectral reflectance and CO2 exchange in European mountain grasslands
In this paper we explore the skill of hyperspectral reflectance measurements and vegetation indices (VIs) derived from these in estimating carbon dioxide (CO2) fluxes of grasslands. Hyperspectral reflectance data, CO2 ...
A Comparison of the Signal from Diverse Optical Sensors for Monitoring Alpine Grassland Dynamics
Grasslands cover up to 40% of the mountain areas globally and 23% of the European Alps and affect numerous key ecological processes. An increasing number of optical sensors offer a great opportunity to monitor and address ...
Influence of physiological phenology on the seasonal pattern of ecosystem respiration in deciduous forests
Understanding the environmental and biotic drivers of respiration at the ecosystem level is a prerequisite to further improve scenarios of the global carbon cycle. In this study we investigated the relevance of physiological ...
