Description: GRACED2021-Near-real-time global gridded daily CO2 emissions 2021 The website: https://carbonmonitor-graced.com In an era of rapid upheavals, global near-real-time and fine-grid carbon dioxide (CO2) emissions data are essential to monitoring the distribution of emissions in space and time and achieving carbon neutrality worldwide. To address this need, we presented the near-real-time Global Gridded Daily CO2 Emissions Dataset (GRACED) throughout 2021. GRACED provides gridded CO2 emissions at a 0.1° × 0.1° spatial resolution and 1-day temporal resolution from cement production, and from fossil fuel combustion over seven sectors (power; industry; residential consumption; ground transportation; international aviation; international shipping; domestic aviation). GRACED data are made freely available to the public and the scientific community in the belief that their wide dissemination will lead to greater understanding and new scientific insights. The availability of these data does not constitute publication of the data. The data providers rely on the ethics and integrity of the user to ensure that they receive fair credit for their work. If the data are obtained for potential use in a publication or presentation, we kindly ask you to inform us at the outset of the nature of this work. If the GRACED data are essential to the work, or if an important result or conclusion depends on the GRACED data, co-authorship may be appropriate. This should be discussed at an early stage in the work. Manuscripts using the GRACED data should be sent for review before they are submitted for publication so we can ensure that the quality and limitations of the data are accurately represented. Please check the README.txt file for more details.
