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.
