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. 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. It was measured by Hammer et.al. (2022) combining Aerosol Optical Depth retrievals from multiple satellite algorithms.
