AB  - As the world’s largest source of methane emissions, accurately measuring and tracking China’s emissions across various sectors is essential for global climate change efforts. Methane, a potent greenhouse gas, is emitted from diverse anthropogenic and natural sources, many of which exhibit pronounced temporal variability. In particular, emissions from rice cultivation, energy use, and livestock management show strong seasonal patterns, yet high-frequency and spatially detailed methane emission inventories have been lacking. This study introduces the Monthly Methane Emission Inventory for China’s Provinces (MMCP), a comprehensive dataset covering the period from January 2013 to December 2022. The dataset includes emissions data from eight key sectors: coal mining, oil and gas systems, energy combustion, rice cultivation, livestock, solid waste, wastewater, and wetlands. By offering sector-specific and temporally resolved emission estimates, MMCP serves as a valuable resource for scientific research, policy evaluation, and emission mitigation planning. This inventory facilitates improved understanding of emission trends and supports more accurate modeling of atmospheric methane concentrations and climate feedbacks.The MMCP dataset contains monthly methane data covering 31 provincial-level administrative regions across mainland China from January 2013 to 2022, which covers the eight emission sources mentioned above. The inventory compilation follows the 2006 IPCC Guidelines for National Greenhouse Gas Inventories and its 2019 Refinement, and adopts a bottom-up accounting approach. Differentiated calculation schemes are selected according to data availability and emission characteristics of each sector: emissions from fossil fuel combustion, oil and gas exploitation, and coal mining industries are directly estimated using daily and monthly activity data. In contrast, only annual statistical data are available for sectors including biomass burning, rice cultivation, and s
