ODIAC Fossil Fuel CO2 Emissions Dataset

The Open-Data Inventory for Anthropogenic Carbon dioxide (ODIAC) is a high-spatial resolution global emission data product of CO2 emissions from fossil fuel combustion (Oda and Maksyutov, 2011). In 2009, the first version of ODIAC was developed by Drs. Tomohiro Oda (now at the Universities Space Research Association, USRA) and Shamil Maksyutov under the Greenhouse gases Observing SATellite (GOSAT) project at the National Institute for Environmental Studies (NIES) in Japan.
ODIAC pioneered the combined use of space-based nighttime light data and individual power plant emission/location profiles to estimate the high-resolution spatial extent of country fossil fuel CO2 emissions. With the innovative emission modeling approach, ODIAC achieved the fine picture of global fossil fuel CO2 emissions at a 1x1km, possibly the most beautiful global picture of man-made emissions. As seen in a number of publications in the literature, the ODIAC emission data product has been widely used by the international research community for a variety of research applications (e.g. CO2 flux inversion, urban emission studies, and observing system design experiments) and beyond.
Since its original publication in 2011, the ODIAC team has made numerous modifications to the ODIAC emission model, and updated and upgraded the emission data product (see Oda et al. 2018). On this data site, the latest version of the ODIAC emission data product (ODIAC2024, 2000-2023) is available for download. Previous versions of the emission data product, including the original version (ODIAC v1.7, 1980-2007), as published by Oda and Maksyutov (2011), are also archived, but only for reference purposes. The team encourages data users to use the latest, updated emission product (currently, ODIAC2024) for their research applications, as the emission estimates included in previous versions of the data product are considered to be outdated once new product becomes available. The details of the ODIAC emission model/data product are described elsewhere (Oda and Maksyutov, 2011; Oda et al., 2018).

人为二氧化碳开放数据清单（Open-Data Inventory for Anthropogenic Carbon dioxide，ODIAC）是一款具有高空间分辨率的全球化石燃料燃烧二氧化碳排放数据产品（Oda与Maksyutov，2011）。2009年，ODIAC首个版本由Tomohiro Oda博士（现任职于美国大学空间研究协会（Universities Space Research Association，USRA））与Shamil Maksyutov博士，在日本国立环境研究所（National Institute for Environmental Studies，NIES）的温室气体观测卫星（Greenhouse gases Observing SATellite，GOSAT）项目下开发完成。
ODIAC首次开创性地将天基夜间灯光数据与单个发电厂的排放/位置档案相结合，用以估算各国化石燃料二氧化碳排放的高分辨率空间分布范围。凭借创新性的排放建模方法，ODIAC实现了1千米×1千米分辨率下的全球化石燃料二氧化碳排放精细刻画，这或许是目前最为清晰精准的全球人为碳排放图景。正如诸多已发表文献中所呈现的那样，ODIAC排放数据产品已被国际科研学界广泛应用于各类研究场景，例如二氧化碳通量反演、城市排放研究以及观测系统设计实验等诸多领域。
自2011年首次发表以来，ODIAC研发团队对ODIAC排放模型进行了多次改进，并对排放数据产品进行了更新与升级（详见Oda等，2018）。本数据平台目前可下载ODIAC排放数据产品的最新版本（ODIAC2024，时间范围为2000年至2023年）。此前发布的各版本排放数据产品同样已归档留存，其中包括Oda与Maksyutov（2011）发表的原始版本（ODIAC v1.7，时间范围为1980年至2007年），但仅作参考使用。研发团队建议数据使用者在研究中使用最新的升级版本（当前为ODIAC2024），因为当新版本发布后，旧版数据产品中的排放估算结果将被视为过时内容。ODIAC排放模型与数据产品的详细信息可参考其他文献（Oda与Maksyutov，2011；Oda等，2018）。
