Gridded model estimates of nitrate-N stored in the vadose (unsaturated) zone at the global scale from 1900 to 2000

Gridded model estimates of nitrate-N stored in the vadose (unsaturated) zone. This dataset presents annual gridded estimates of nitrate stored in the vadose zone for 1900 - 2000 on a 0.5 degree grid (units: kg N/grid cell). Data are supplied as a single netCDF for all years. This data was derived by Ascott et al. (2017). Global models of depth to groundwater table, subsurface porosity and groundwater recharge were used to derive estimates of nitrate travel time in the vadose zone. The travel time was combined with annual estimates of nitrate leaching from the base of the soil zone for 1900 - 2000 to estimate total nitrate stored in the vadose zone. For full details of the dataset derivation, please refer to Ascott et al. (2017). Ascott, M.J., Gooddy, D.C., Wang, L., Stuart, M.E., Lewis, M.A., Ward, R.S. and Binley, A.M.

Statement: This dataset was derived Ascott et al. (2017). Nitrate travel time in the vadose zone was derived by combining global models of groundwater table, subsurface porosity and groundwater recharge. Model estimates of nitrate leaching from the base of the soil zone was combined with estimates of travel time to derive the total amount of nitrate stored in the vadose zone. Full details of the methodology are described in Ascott et al. (2017). Ascott, M.J., Gooddy, D.C., Wang, L., Stuart, M.E., Lewis, M.A., Ward, R.S. and Binley, A.M.
