Abstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, terrestrial biosphere – global budget is important to better understand cycle, support development climate policies, project future change. Here we describe data sets methodology quantify five major components uncertainties. CO2 from fossil fuels industry (EFF) are based on energy statistics cement production data, respectively, while land-use change (ELUC),...
Abstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, terrestrial biosphere – “global budget” is important to better understand global cycle, support development climate policies, project future change. Here we describe data sets methodology quantify all major components budget, including uncertainties, based on combination a range data, algorithms, statistics, model estimates interpretation by broad scientific...
Volcanic aerosols from the 1991 Mount Pinatubo eruption greatly increased diffuse radiation worldwide for following 2 years. We estimated that this increase in alone enhanced noontime photosynthesis of a deciduous forest by 23% 1992 and 8% 1993 under cloudless conditions. This finding indicates aerosol-induced volcano terrestrial carbon sink contributed to temporary decline growth rate atmospheric dioxide after eruption.

This paper examines available data, develops a strategy and presents monthly, global time series of fossil-fuel carbon dioxide emissions for the years 1950-2006. monthly was constructed from detailed study data 21 countries that account approximately 80% total emissions. These were then used in Monte Carlo approach to proxy all remaining countries. The proportional-proxy methodology estimates by fuel group fraction annual emitted each country month. Emissions solid, liquid gas fuels are...
Three uncertainty assessments associated with the global total of carbon dioxide emitted from fossil fuel use and cement production are presented. Each assessment has its own strengths weaknesses none give a full emission estimates. This approach grew out lack independent measurements at spatial temporal scales interest. Issues dependent data considered as well relationships data. The result is multifaceted examination three collectively range that spans 1.0 to 13% (2 σ). Greatly simplifying...
Abstract. Due to a current lack of physical measurements at appropriate spatial and temporal scales, all global maps distributions fossil fuel carbon dioxide (FFCO2) emissions use one or more proxies distribute those emissions. These distribution schemes introduce additional uncertainty into these maps. This paper examines the associated with magnitude gridded FFCO2 is same scales as mass includes contributions from spatial, temporal, proxy, components used create map Throughout this...
Abstract. The Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), USA has provided scientific data management support for the US Department of Energy and international climate change science since 1982. Among many archived available from CDIAC are collections long-term measurement projects. One current example is AmeriFlux network. provides continuous measurements forests, grasslands, wetlands, croplands in North, Central, South America offers...
Abstract. Ecosystem-scale manipulation experiments represent large science investments that require well-designed data acquisition and management systems to provide reliable, accurate information project participants third party users. The SPRUCE (Spruce Peatland Responses Under Climatic Environmental Change, http://mnspruce.ornl.gov) is such an experiment funded by the Department of Energy's (DOE), Office Science, Terrestrial Ecosystem Science (TES) Program. experimental mission assess...
