The ORNL DAAC is pleased to announce the release of two data sets from the North American Carbon Program (NACP) Mid-Continent Intensive (MCI) Campaign:
- NACP MCI: CO2 Flux from Inversion Modeling, Upper Midwest Region, USA, 2007 . Data set prepared by A.E. Schuh, T. Lauvaux, S.M. Ogle, K.J. Davis, A.S. Denning, N.L. Miles, S.J. Richardson, and M. Uliasz. This data set provides estimates of Net Ecosystem Exchange (NEE) flux for the U.S. Upper Midwest at 0.5-degree resolution for the year 2007. Estimates were produced by two atmospheric CO2 inversion systems (“top-down”), referenced as the continental Colorado State University (CSU) inversion and the mesoscale Pennsylvania State University (PSU) inversion.
CO2 observations used by the inversion systems were results from a network of instrumented towers in the region. The NEE estimates were produced for comparison with CO2 fluxes derived from "bottom-up" inventory estimates.
- NACP MCI: CO2 Emissions Inventory, Upper Midwest Region, USA, 2007. Data set prepared by S.M. Ogle, A.E. Schuh, T.O. West, K.R. Gurney, L.S. Heath, J.L. McCarty, J.E. Smith, F.J. Breidt, and D. Cooley. This data set provides a "bottom-up" carbon dioxide (CO2) emissions inventory for the mid-continent region of the United States for the year 2007. Emissions for the MCI region included data from fossil and bioenergy combustion, forest biomass, harvested wood products, cropland harvested grain, human and livestock respiration, residue burning, decomposition of waste landfills, and soil organic carbon stock changes in cropland, grassland, and forest soil.
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.
