Metadata for Spatio-temporal assessment of GHG emissions and nutrient sequestration linked to agronutrient runoff in global wetlands

We distribute the output data from our global simulation of wetlands affected by agricultural runoff. The computational domain involves about 25,000 grid cells globally distributed describing the wetlands, and neglects lakes, rivers, rice paddies, saline estuaries, salt marshes, and reservoirs (Poulter et al., 2017). We include 14 maps and videos for the principal greenhouse gasses GHG (CH₄, CO₂, and N₂O), wetland extension area, soil temperature, soil moisture, long-term average soil pH, carbon input, long-term average annual carbon, long-term average soil carbon, nitrogen, and sulfur sequestration rate. This data release includes also the following plant-dependent variables: CH₄ plant emission efficiency for aerenchyma transport, C:N and C:S ratio of litter in grassland, forest, and shrubland, N₂ fixation rate in grassland, forest, shrubland, and wetland, and the average root density for forest, grassland, shrublands, and wetland.
