Water Pollution Indicators for the World Water Development Report II

Gridded fields of nitrogen (N) loads and flux. Mobilizable N (N loads)
represent the amount of N on the land surface that is available to be
transported to aquatic systems. N fluxes represent the subsequent
riverine nitrogen fluxes at the basin scale (Vorosmarty et al.,
2000a,b; Fekete et al., 2001), for the contemporary setting
(mid-1990's) in Green et al. (2004).
