Air Condition Risk

Air condition indicates whether the air quality is fit for human use and ecosystems. This indicator is based on PM2.5 concentrations based on the Global Annual PM2.5 Grids data combining Aerosol Optical Depth retrievals from multiple satellite algorithms. PM 2.5 is the annual global surface concentration (micrograms per cubic meter) of all composition ground-level fine particulate matter of 2.5 micrometers or smaller. Exposure to high average concentrations of PM2.5 over time has been a reliable predictor of heightened mortality. This layer is part ot the WWF Risk Filter Suite
