ODIAC Fossil fuel emission 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. On this data site, the latest version of ODIAC emission data (ODIAC2018, 2000-2017) 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. The details of the recent version of ODIAC emission model/data will be described in elsewhere (Oda et al., 2018).

Currently ODIAC emission data is being developed under a NASA funded project (Project lead: T. Oda). The team is improving the ODIAC model using new nighttime satellite environmental product developed at NASA Goddard Space Flight Center, using data collected by the Suomi National Polar-orbiting Program (NPP) satellite.

What's New

Jan 30, 2019
The ODIAC team estimated that the total global fossil fuel CO2 emission hit 10 PgC in 2017. Dr. Oda and collaborators Prof Marland and Mr. Boden published their brief comment as a Correspondence in Nature.
The 10 PgC emission estimate is included in ODIAC2018.

The year 2018 version of ODIAC fossil fuel CO2 emission dataset (ODIAC2018, 2000-2017) is now available for download.
Oct 27, 2017
The year 2017 version of ODIAC fossil fuel CO2 emission dataset (ODIAC2017, 2000-2016) is now available for download.
Apr 14, 2017
DOI (Digital Object Identifier) has been minted for the ODIAC dataset. [doi : 10.17595/20170411.001]
We are now distributing the ODIAC dataset under the Creative Commons Attribution 4.0 International (CC BY 4.0) license.
Nov 2, 2016
We found the map/coordinate information in the 1x1km GeoTIFF version of ODIAC2016 files was not accurately specified. We have fixed this issue and are distributing a revised version of 1x1km GeoTIFF ODIAC2016 files.
The 1x1deg version of ODIAC2016 files was not affected by this issue.
Sep 30, 2016
The year 2016 version of ODIAC fossil fuel CO2 emission dataset (ODIAC2016, 2000-2015) is now available for download.
May 19, 2016
We found antarctic fishery emissions (<3K TC/yr) were distributed incorrectly using a vertically flipped land mask data in the 1x1deg netCDF version of ODIAC2015a files. We have stopped the data distribution since 19th of May and we are now distributing a revised version of 1x1deg ODIAC2015a files. The 1x1km version of ODIAC2015a files was not affected by the issue.
Apr 19, 2016
The year 2015 version of ODIAC fossil fuel CO2 emission dataset (ODIAC2015a, 2000-2014) is now available for download. ODIAC2015a is based on emission estimates projected using the latest global fuel use statistics from BP.
