This dataset is a model output from the JULES land surface model driven with the Watch Forcing Data methodology applied to Era-Interim (WFDEI) data. It provides monthly global methane emissions from natural wetlands on 0.5 x 0.5 degree grid between 1980-2014. It includes the following variables:
· fch4_wetl: modelled methane flux from natural wetland, in mg CH4 m-2 day-1.
· fwetl: fraction of wetland.
· cs: soil carbon in each of these four soil carbon pools: decomposable plant material, resistant plant material, microbial biomass and humus), in kg m-2
· t_soil: sub-surface temperature of the four modelled soil layers (0-0.1 m, 0.1-0.35 m, 0.35-1.0 m and 1.0-2.0 m), in K.

Data is produced by the JULES v 4.5 model. JULES was driven with the Watch Forcing Data methodology applied to Era-Interim (WFDEI) meteorological data. Ancillary data used in the simulation are: (1) Van Genuchten soil properties from the Harmonised World Soil Database (HWSD); (2) International Geosphere-Biosphere Programme (IGBP) land cover data; (3) High-resolution global topographic index values (Marthews, 2015; https://doi.org/10.5285/6b0c4358-2bf3-4924-aa8f-793d468b92be). JULES output was reprojected on to a 2D grid and the natural wetland methane emissions were scaled to give a global total of 180 Tg of methane in 2000 in post processing.
