Allows users to explore, visualize and interpret national to global carbon data from both human activities and natural processes.
Inputs include data and models that have been collected from various contributors. Contributed inputs have been grouped into four main categories: fossil fuel and land use change emissions, atmospheric inversions (estimates of surface-to-atmosphere net carbon fluxes), land models (terrestrial carbon models), and ocean models.
Outputs are grouped into three main categories that are meant for users with varying levels of technical background.
Outreach – offers educational, interactive snapshots of carbon dioxide emissions in the past, present and future. Users can get a visual picture of when and where emissions have occurred, and an overview of the projected consequences of possible future atmospheric CO2 levels (e.g. sea level rise, ice cover.
Emissions – offers multiple ways to view carbon emissions data. Users can select and compare the country, region, or political grouping (e.g. OECD) of interest; the source of emissions (e.g. fossil fuels, land use change); and the units of carbon emissions (e.g. total megatonnes, tons per person). They can visualize this data in a number of ways, including as a map, chart, country ranking, and other formats at time steps from 1960 – 2012.
Research – lets users create custom global and regional maps and time series of carbon fluxes from datasets and research models. The maps display either ocean or terrestrial flux depending on the specific model(s) chosen. Users have some control in selecting the time period and averaging period of these maps and graphs, and their visual parameters (e.g. colors, legends).
Restrictions and Limitations:
The Global Carbon Atlas presents general data on carbon emissions and fluxes at the national and global levels. Uses for the tool are therefore intended to be at this large scale. For land managers, the Atlas may be useful for placing forest- and project-level carbon emissions and fluxes within the context of total national or global values. This could help with understanding how forest management actions could contribute as a whole to emitting or sequestering carbon dioxide. Many of the tools could also be used for outreach and education purposes.
There are many different inversion, terrestrial and ocean carbon models, ranging from the simple to the complex. The Atlas uses a subset of these, but are other scientifically valid datasets and models that are not represented in these tools.
Please keep in mind that carbon emissions are estimated at the national and global level based on available data, and these data may vary in collection method and accuracy from country to country. Before using any of the data, users should carefully evaluate the accuracy, currency, completeness and relevance for their purposes.
If you use these data, Global Carbon Atlas requires you to cite the original data sources. All of the information needed for the citations can be found on the website under Contributors.
