Global wetland CH4 emissions for 2000-2021

This repository contains all the data needed to reproduce the results in Zhang et al., 2023. Zhang Z., Poulter, B., Feldman A., Ying Q., Ciais P., Peng S., Li X., 2023. Recent intensification of wetland methane feedback, in revision in Nature Climate Change. The files are two estimates for global wetland methane emissions simulated by LPJ-wsl model for the period of 2000-2021 and a mask used for defining regions. The ground-based input dataset is a monthly climatic observation based on meteorological stations developed by Climatic Research Unit (CRU), University of East Anglia. The reanalysis-based climate dataset is a daily climatic dataset from 1 hourly reanalysis Modern-Era Retrospective analysis for Research and Applications Version2 (MERRA2). The unit of wetland CH4 emissions is g CH4 mon-1 per 0.5deg cell area. For more details about LPJ-wsl model, see Zhang et al., (2017, 2018).
