Satellite-Based Monitoring of Methane Emissions from China's Rice Hub

IntroductionWe perform a high-resolution inversion of atmospheric methane observations from the TROPOMI satellite observations to infer monthly rice methane emissions for 2021 from Northeast China.Data filesMonthly optimized methane emissions: NortheastChina_CH4Flux_{inversion case}_2021{month}.nc- 9 members of the date sets: SRON-E1(base), SRON-E1-SA-down, SRON-E1-SA-up, SRON-E1-SA-nondiag, SRON-E1-wet, SRON-E2, SRON-E3, WFMD-E1, WFMD-E2Data infomation- Variables: CH4_Flux_{emi_sector} (unit: kg/m2/s) and area (unit: m2).

Emission sectors include coal, oil, gas, wastewater, livestock, landfills, rice, wetlands, seeps, termites, biosmass burning, and other anthropogenic- Spatial resolution: 0.5° x 0.625°- Period: the year 2021- Domain: Northeast China (39°N – 54°N, 119°E – 137°E)
