Terrestrial ecosystem production: A process model based on global satellite and surface data
This paper presents a modeling approach aimed at seasonal resolution of global climatic and edaphic controls on patterns of terrestrial ecosystem production and soil microbial respiration. We useExpand
A narrow-waveband spectral index that tracks diurnal changes in photosynthetic efficiency
Abstract We present a new “physiological reflectance index” (PRI) isolated from narrow waveband spectral measurements of sunflower canopies. This index correlates with the epoxidation state of theExpand
Energy balance closure at FLUXNET sites
A comprehensive evaluation of energy balance closure is performed across 22 sites and 50 site-years in FLUXNET, a network of eddy covariance sites measuring long-term carbon and energy fluxes inExpand
Contributions to accelerating atmospheric CO2 growth from economic activity, carbon intensity, and efficiency of natural sinks
The growth rate of atmospheric carbon dioxide (CO2), the largest human contributor to human-induced climate change, is increasing rapidly and three processes contribute to this rapid increase: emissions, global economic activity, carbon intensity of the global economy, and the increase in airborne fraction of CO2 emissions.

A Revised Land Surface Parameterization (SiB2) for Atmospheric GCMS. Part I: Model Formulation
Abstract The formulation of a revised land surface parameterization for use within atmospheric general circulation models (GCMs) is presented. The model (SiB2) incorporates several significantExpand
Revisiting the commons: local lessons, global challenges.
New insights about the management of large-scale resources that depend on international cooperation and the conditions most likely to favor sustainable uses of common-pool resources are discussed. Expand
Global net primary production: Combining ecology and remote sensing
Terrestrial net primary production (NPP) is sensitive to a number of controls, including aspects of climate, topography, soils, plant and microbial characteristics, disturbance, and anthropogenicExpand
The velocity of climate change
A new index of the velocity of temperature change (km yr-1), derived from spatial gradients and multimodel ensemble forecasts of rates of temperature increase in the twenty-first century, indicates management strategies for minimizing biodiversity loss from climate change. Expand
Global scale climate–crop yieldrelationships and the impacts of recentwarming
Changes in the global production of major crops are important drivers of food prices, food security and land use decisions. Average global yields for these commodities are determined by theExpand
