TL;DR
This paper introduces GRACED, a high-resolution, near-real-time global dataset of daily CO2 emissions from fossil fuel and cement production, enabling detailed monitoring of emission changes across sectors and time.
Contribution
The study presents the first high-resolution, daily global CO2 emission dataset combining multiple data sources for near-real-time monitoring.
Findings
Revealed sector-specific emission changes between 2019 and 2020.
Demonstrated the dataset's ability to track emission rebounds post-COVID-19.
Enabled insights into the spatial and temporal dynamics of fossil CO2 emissions.
Abstract
Precise and high-resolution carbon dioxide (CO) emission data is of great importance of achieving the carbon neutrality around the world. Here we present for the first time the near-real-time Global Gridded Daily CO Emission Datasets (called GRACED) from fossil fuel and cement production with a global spatial-resolution of 0.1 by 0.1 and a temporal-resolution of 1-day. Gridded fossil emissions are computed for different sectors based on the daily national CO emissions from near real time dataset (Carbon Monitor), the spatial patterns of point source emission dataset Global Carbon Grid (GID), Emission Database for Global Atmospheric Research (EDGAR) and spatiotemporal patters of satellite nitrogen dioxide (NO) retrievals. Our study on the global CO emissions responds to the growing and urgent need for high-quality, fine-grained near-real-time CO2…
