Dataset for “Monthly Gridded Data Product of Northern Wetland Methane Emissions Based on Upscaling Eddy Covariance Observations”

This dataset provides wetland methane (CH₄) emissions, their uncertainties and underlying CH₄ flux densities north from 45 N using three different wetland maps. The data products are derived using data from several eddy covariance CH₄ flux sites, random forest machine learning algorithms and three prescribed wetland maps. The data are at 0.5 by 0.5 deg or 1 by 1 deg resolution, depending on the wetland map used. The dataset covers years 2013 and 2014. CH₄ flux densities are provided only for grid cells with > 5 % wetland coverage.

The three data products are provided in netCDF format files (.nc). Please see more details in the attributes saved in the netCDF files.

RF-DYPTOP.nc
Upscaling based on DYPTOP dynamic wetland map. At 1 by 1 deg resolution.

RF-GLWD.nc
Upscaling using GLWD static wetland map. At 0.5 by 0.5 deg resolution.

RF-PEATMAP.nc
Upscaling using PEATMAP static wetland map. At 0.5 by 0.5 deg resolution.
