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

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

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

To provide tabular data on the trends of chlorophyll-a concentration on a pixel by pixel basis for identifying areas with improving, declining, and stable coastal water quality that can provide guidance for decision making in the context of coastal management.

To provide an assessment of potential climate change impacts on world crop production.

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

To provide information on global land use for research on human-environment interactions.

To provide estimates of urban and rural populations and land areas in the low elevation coastal zone.

To provide tabular data on environmental conditions (elevations, climate, coastal) in which people reside.

To provide geographical portraits of vulnerability designed to incorporate both exposure to climate change and national capacities to adapt.

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

To provide an updated map of wild areas in geographic projection which can be used in wildlife conservation planning, natural resource management, and research on human-environment interactions.

To provide an updated map of anthropogenic impacts on the environment in geographic projection which can be used in wildlife conservation planning, natural resource management, and research on human-environment interactions.
