Global rice paddy methane emissions from 1961 to 2020

This dataset includes supplementary data supporting the study, "Global rice methane emissions tripled in the past six decades". The emissions were simulated independently using three methods: a process-based model (CH4MOD), a machine learning model Radom forest (CH4-ML), and the improved emission-factor method (CH4-EF) following the IPCC guidelines. Including:

Data S1. Global CH₄ emissions from 1961 to 2020 estimated by CH4MOD, CH4-ML, CH4-EF, and other studies. Related to Figure 1a. (.csv)

Data S2. Average annual CH₄ emissions differences between CH4MOD, CH4-ML and CH4-EF during 1960s and 2010s. Related to Figure 1b-e. (.tif)

Data S3. Spatial distribution of CH₄ emissions in 2010s and the changes relative to the 1960s, estimated by the average of CH4MOD and CH4-ML. Related to Figure 2a-b. (.tif)

Data S4. Annual CH₄ emissions in global total and 15 major rice-producing countries from 1961 to 2020, , estimated by the average of CH4MOD and CH4-ML. Related to Figure 2c. (.csv)

Data S5. Change of rice harvested area and CH₄ flux in the 2010s relative to the 1960s, estimated by the average of CH4MOD and CH4-ML. Related to Figure 3a-b. (.tif)
