Global Nitrogen Loads and Fluxes for the Mid-1990s

Gridded global datasets of nitrogen pollution indicators, including mobilizable nitrogen loads and riverine nitrogen fluxes. The data was produced by Green et al. (2004) for the World Water Development Report II, representing the contemporary setting of the mid-1990s. It consists of three raster files detailing total and dissolved inorganic nitrogen fluxes at the basin scale.

Use Cases

• Modeling global nitrogen transport to aquatic systems based on mobilizable nitrogen loads.
• Assessing basin-scale water pollution using total and dissolved inorganic nitrogen flux data.
• Calibrating hydrological models with gridded, spatially explicit nitrogen indicators.
• Analyzing historical nutrient pollution for the mid-1990s time period referenced in the description.

Strengths

• Provides three distinct, spatially gridded variables for nitrogen analysis.
• Data is associated with a specific scientific publication (Green et al., 2004) and report (WWDR II).
• Covers a global spatial scale for a consistent temporal period (mid-1990s).

Limitations

• Last updated 1999-12-31 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias inherent to the mid-1990s snapshot.
