FLUXNET: A New Tool to Study the Temporal and Spatial Variability of Ecosystem-Scale Carbon Dioxide, Water Vapor, and Energy Flux Densities
FLUXNET is a global network of micrometeorological flux measurement sites that measure the exchanges of carbon dioxide, water vapor, and energy between the biosphere and atmosphere. At present overExpand

Reduction of forest soil respiration in response to nitrogen deposition
The use of fossil fuels and fertilizers has increased the amount of biologically reactive nitrogen in the atmosphere over the past century. As a consequence, forests in industrialized regions haveExpand

Gap filling strategies for defensible annual sums of net ecosystem exchange
Abstract Heightened awareness of global change issues within both science and political communities has increased interest in using the global network of eddy covariance flux towers to more fullyExpand

Modeling and measuring the effects of disturbance history and climate on carbon and water budgets in evergreen needleleaf forests
The effects of disturbance history, climate, and changes in atmospheric carbon dioxide (CO2) concentration and nitrogen deposition (Ndep) on carbon and water fluxes in seven North American evergreenExpand

Global patterns of land-atmosphere fluxes of carbon dioxide, latent heat, and sensible heat derived from eddy covariance, satellite, and meteorological observations
We upscaled FLUXNET observations of carbon dioxide, water, and energy fluxes to the global scale using the machine learning technique, model tree ensembles (MTE). We trained MTE to predict site-levelExpand

Environmental controls over carbon dioxide and water vapor exchange of terrestrial vegetation
The objective of this research was to compare seasonal and annual estimates of CO2 and water vapor exchange across sites in forests, grasslands, crops, and tundra that are part of an internationalExpand

Old-growth forests as global carbon sinks
Old-growth forests remove carbon dioxide from the atmosphere at rates that vary with climate and nitrogen deposition. The sequestered carbon dioxide is stored in live woody tissues and slowlyExpand

Seasonal and annual respiration of a ponderosa pine ecosystem
The net ecosystem exchange of CO2 between forests and the atmosphere, measured by eddy covariance, is the small difference between two large fluxes of photosynthesis and respiration. ChamberExpand

Evaluation of remote sensing based terrestrial productivity from MODIS using regional tower eddy flux network observations
The Moderate Resolution Spectroradiometer (MODIS) sensor has provided near real-time estimates of gross primary production (GPP) since March 2000. Expand

CO2 Balance of Boreal, Temperate, and Tropical Forests Derived from a Global Database
Terrestrial ecosystems sequester 2.1 Pg of atmospheric carbon annually. A large amount of the terrestrial sink is realized by forests. However, considerable uncertainties remain regarding the fate ofExpand
