Global near-real-time CO2 emission

Timely, comprehensive and accurate dataset of CO2 emissions from fossil fuel combustion and cement production are fundamental prerequisites to understanding the global carbon cycle and designing evidenced-based policies for reducing carbon emissions. Here we provided daily CO2 emission data record started from Jan. 1^st 2019. The dataset uncovered the daily CO2 dynamics through daily, weekly and seasonal variations as well as the change of daily CO2 due to the holiday events and the impact of COVID-19 pandemic.Such near-real-time CO2 dataset would be of great advantage to further monitoring the human activities and to capture the impacts of COVID-19 for long term.<br>

及时、全面且精准的化石燃料燃烧与水泥生产二氧化碳（CO₂）排放数据集，是理解全球碳循环、制定循证减排政策的核心前提。本数据集提供了自2019年1月1日起的每日二氧化碳排放数据记录，涵盖了每日、每周及季节尺度下的碳排放动态，同时揭示了节假日事件与新冠疫情（COVID-19 pandemic）对每日碳排放的影响。此类近实时二氧化碳数据集，可为进一步开展人类活动监测以及长期追踪新冠疫情的影响提供显著助益。
