High-resolution (10 km × 10 km) anthropogenic methane emissions in China in 2020

<p>This dataset is a comprehensive and bottom-up estimate of China&#39;s anthropogenic CH4 emissions in 2020 from 45 sub-sectors and ~130,000 point sources. Generally, we classify all sources into two major categories: fossil-fuel system and food system. Fossil-fuel system releases CH4 emissions throughout the fossil-fuel related activities, which contains coal/gas/oil supply chain and fossil-fuel related waste management in this study. Food system contains rice cultivation, livestock, biomass burning and food-related waste management in this study. We allocate the annual CH4 emissions in 2020 at a spatial resolution of 0.1&deg; &times; 0.1&deg; (nearly 10km &times;10km), wherein emissions from point sources are precisely allocated at their location information. The remaining anthropogenic sources in provincial level are allocated by the corresponding surrogate indexes, such as gridded gross domestic product (GDP), population, cultivated area and the source-specific surrogate indexes.</p>
