ODIAC Fossil Fuel CO2 Emissions Dataset

The Open-Data Inventory for Anthropogenic Carbon dioxide (ODIAC) is a high spatial resolution emission dataset for CO2 emissions from fossil fuel combustion (Oda and Maksyutov, 2011). In 2009, the original version of ODIAC was developed by Drs. Tomohiro Oda (now at USRA/NASA Goddard) and Shamil Maksyutov at the Greenhouse Gases Observing SATellite (GOSAT) project, National Institute for Environmental Studies (NIES).

ODIAC first introduced the combined use of nightlight data and individual power plant emission/location profiles to estimate the spatial extent of fossil fuel CO2 emissions and it achieved the global emission fields at a 1x1km. The ODIAC emission data has been widely used by the international carbon cycle research community and appeared in a number of publications in the literature.

Since its original publication in 2011, numerous modifications have been made to the ODIAC emission model and the emission data have been updated (Oda et al., in prep). On the ODIAC data site "http://db.cger.nies.go.jp/dataset/ODIAC/", the latest version of ODIAC emission data is available for download. Previous versions of ODIAC emission data including the original version of the ODIAC data (ODIAC v1.7, 1980-2007) as published as Oda and Maksyutov (2011), are also archived for reference purpose.
