New Datasets From The North American Carbon Program (NACP)

The ORNL DAAC is pleased to announce the release of four data sets associated with The North American Carbon Program (NACP):

NACP Integrated Wildland and Cropland 30-m Fuel Characteristics Map, U.S.A., 2010, http://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1163

NACP Regional: National Greenhouse Gas Inventories and Aggregated Gridded Model Data, http://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1179

NACP Site: Terrestrial Biosphere Model and Aggregated Flux Data in Standard Format, http://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1192

NACP Site: Tower Meteorology, Flux Observations with Uncertainty, and Ancillary Data, http://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1178

The North American Carbon Program (NACP), is a multi-disciplinary research program designed to obtain scientific understanding of North America's carbon sources and sinks and of the changes in carbon stocks needed to meet societal concerns, and to provide tools for decision makers. NACP began in 2002 and continues to date. The NACP data collection contains continental carbon budgets, dynamics, processes, and management of the sources and sinks of carbon dioxide, methane, and carbon monoxide in North America and in adjacent ocean regions.

The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data.

Global Carbon Project Releases 2012 Global Carbon Budget Update

Josep (Pep) Canadell, from the Global Carbon Project, informed the science community that the Global Carbon Project has just released the 2012 update of the Global Carbon Budget.

This year’s budget includes the latest trends in global and regional carbon dioxide emissions and sinks, and analysis of how these trends relate to keeping global temperatures below 2C.

A commentary in Nature Climate Change focuses on comparing observed emission trends with four generations of IPCC emissions scenarios and considers the mitigation challenge to keep temperatures below 2C.

A detailed manuscript in Earth System Science Data Discussions describes the full carbon budget (emission sources and sinks), and the methods and data used.
