To provide a continuous surface of concentrations (micrograms per cubic meter) of particulate matter of 2.5 micrometers or smaller (PM2.5) for health and environmental research.

To provide tabular data to researchers without GIS capabilities who need data on population and land area by country across a range of physical characteristics. These include measures such as the number of persons living within coastal zones, the percent of a region within specific elevation strata, or the number of persons living within different climate zones.

To provide quantitative metrics for evaluating a country's environmental performance in different policy categories relative to clearly defined targets.

To provide a raster representation of urban areas (or urban mask) for use with GRUMP population grids or other data sets.

To provide populated place (point) data with consistent population estimates.

To provide a time series of raster population density data for data integration.

To provide phosphorus fertilizer application data that can be used in socioeconomic and ecological modeling and to explore anthropogenic activities on ecosystems.

To provide a geographically explicit and reliable database of reservoirs for the scientific community.

To provide nitrogen in manure production data that can be used in socioeconomic and ecological modeling and to explore anthropogenic activities on ecosystems.

To provide a geographically explicit and reliable database of dams for the scientific community.

To provide annual estimates of anthropogenic global and regional Sulfur Dioxide (SO2) emissions in support of climate, atmospheric or other related research.

To provide phosphorus in manure production data that can be used in socioeconomic and ecological modeling and to explore anthropogenic activities on ecosystems.
