TL;DR: In this paper, a process-based model was used to estimate global patterns of net primary production and soil nitrogen cycling for contemporary climate conditions and current atmospheric CO2 concentration, with most of the production attributable to tropical evergreen forest.

TL;DR: A comparison of 17 global models of terrestrial biogeochemistry with respect to annual and seasonal fluxes of net primary productivity (NPP) for the land biosphere is presented in this article.

TL;DR: In this paper, the authors provide a conceptual framework to guide efforts toward improved estimates of forest net primary production (NPP) in the world's forests, and assess the implications of the limitations of past studies for current understanding of NPP in forest ecosystems, discuss how field NPP* measurements can be used to complement tower-based studies of forest carbon flux, and recommend design criteria for future field studies of Forest NPP.

TL;DR: Seasonal patterns of NPP in South America are correlated with moisture availability in most vegetation types, but are strongly influenced by seasonal differences in cloudiness in the tropical evergreen forests.

TL;DR: In this paper, the concurrent effects of increasing atmospheric CO2 concentration, climate variability, and cropland establishment and abandonment on terrestrial carbon storage between 1920 and 1992 were assessed using a standard simulation protocol with four process-based terrestrial biosphere models.
