To provide an annual global surface of concentrations (micrograms per cubic meter) of mineral dust and sea-salt filtered fine particulate matter of 2.5 micrometers or smaller (PM2.5) in countries and urban areas for large-scale health and environmental research

To provide a high-resolution, longitudinal global data set of extreme urban heat events and urban heat exposure.

To provide data that can be used to calculate trace gas and aerosol emissions due to fires; monitor and assess national efforts to manage emissions.

To provide a global data set of average summer daytime maximum/nighttime minimum land surface temperatures (LSTs) for urban extents, as well as the LST difference between the urban area and the buffer.
