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 a time series of raster population data for ntegration with other data sets

To permit the summation of population values by country/territory and, in combination with other data layers, the summation of population values by irregular areas represented in the other data layers and country/territory.

To permit cartographic display of countries and territories that exactly match the GRUMPv1 population surfaces

To provide land area data for use with GRUMPv1 population and urban data as well as a quantitative measure of resolution of the input spatial units for GRUMPv1.

To permit cartographic display of coastlines that exactly match the GRUMPv1 population surfaces.

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 assist in the country selection process for the Millennium Challenge Corporation by providing indicators of natural resource management and child health that complements the governance, social, and economic indicators used by MCC as country selection criteria.

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

To assist in the country selection process for the Millennium Challenge Account by providing indicators of natural resource management that complements the governance, social, and economic indicators.

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 a gridded version of existing SeaWiFS data in GIS-compatible formats in order to determine concentrations of chlorophyll-a in the coastal water column and to facilitate the integration with other data.
