EPA Air Pollution

Diverse set of data addressing PM 2.5, Ozone, Air Toxics, and Wildfires. Includes both monitor data and modeled data hourly, daily or annual averages. Also includes ancillary data. For example, the Wildfires data includes measures of vulnerability such as Contextual measures of access to care and online content, as well as social vulnerability, chronic disease outcomes, annual air quality levels, and population characteristics help identify at-risk populations and areas vulnerable to disasters and natural hazards. These measures, however, are static and do not reflect changes in levels of vulnerability that may occur over time or after mass evacuations that occur before, during, and after emergencies.
