US Carbon Cycle Science Program
An interagency partnership to provide critical unbiased scientific information on the fate of carbon dioxide in the environment to contribute to the ongoing public dialogue.

Carbon Dioxide Information Analysis Center (CDIAC)
Global-change data and information analysis for the US Department of Energy (DOE). Atmospheric concentrations of carbon dioxide and other radiatively active gases; role of the terrestrial biosphere and oceans in biogeochemical cycles of greenhouse gases; emissions of carbon dioxide; long-term climate trends; effects of elevated carbon dioxide on vegetation; vulnerability of coastal areas to rising sea level.

Mystery of the Missing Carbon
Discusses the BOREAS research program, which investigated the "missing carbon" problem in global carbon cycle studies.

United States Trace Gas Network
The TRAGNET network is meant to accomplish the following two goals: 1. Document contemporary fluxes of CO2, CH4 and N2O between regionally important ecosystems and the atmosphere and 2. Determine the factors controlling these fluxes and improve our ability to predict future fluxes in response to ecosystem and climate change.

The BOREAS Project
The Boreal Ecosystem-Atmosphere Study (BOREAS) is a large-scale international interdisciplinary experiment in the northern boreal forests of Canada. Its goal was to improve our understanding of the boreal forests - how they interact with the atmosphere, how much CO2 they can store, and how climate change will affect them.

Climate and Carbon Cycle Modeling Group (CCCM)
The CCCM is a part of Atmospheric Science Division at Lawrence Livermore National Laboratories. Site provides acces to some of their publications, as well as information on the centre, their models and their projects.

Global Carbon Project
Scientific partnership that aims to develop a complete picture of the global carbon cycle, including both its biophysical and human dimensions together with the interactions and feedbacks between them. A project of the Earth System Science Partnership of the International Geosphere Biosphere Programme (IGBP), World Climate Research Programme (WCRP), and the International Human Dimensions Programme (IHDP)

Fluxnet Canada
A Canadian research network, based on eddy covariance flux measurements, that studies the effects of climate and disturbance on carbon cycling processes in forest and peatland ecosystems.

NOFRETETE: Nitrogen oxides emissions from European forest ecosystems
A Project funded by the European Commission DG Research - V th Framework programme Programme in the thematic programme "Energy, Environment and Sustainable Development", Key Action 2 "Global change, climate and biodiversity"
