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.

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.

Carbon Modeling Consortium - The CMC's mandate is to develop a carbon system model capable of providing assessments of past, present, and future CO2 sources and sinks that cause (and affect) atmospheric carbon dioxide levels. Website describes research and explains the basic features of the carbon cycle.

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

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.

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.
