Daily European biospheric methane emissions estimated with the ecosystem model JSBACH-HIMMELI.

Daily estimates of European biospheric methane emissions from JSBACH-HIMMELI  model from year 2000 to year 2022. JSBACH-HIMMELI is an ecosystem process model based on JSBACH land surface model, YASSO soil carbon model and HIMMELI methane emission model. The gridded fluxes are available with a resolution of 0.1x0.1 degrees and in units of g[C] m-2 hour-1 (m-2 refers to grid cell area). The gridded flux file contains a variable for methane fluxes (ch4flux), including  a sum of methane fluxes from peatlands, inundated lands and mineral soils. More information of the model set-up is documented in Petrescu, A. M. R., et al., The consolidated European synthesis of CH4 and N2O emissions for the European Union and United Kingdom: 1990–2019, Earth Syst. Sci.

Future methane fluxes of peatlands are controlled by management practices and fluctuations in hydrological conditions due to climatic variability.
