Make a map of daily concentrations over several days. The daily air quality can be displayed in terms of the Air Quality Index or in concentration ranges for certain PM species like organic carbon, nitrates, and sulfates. This tool may be useful for tracking an air pollution episode like a wildfire event.
Note: As of March 18, 2013, all PM2.5 AQI values and summaries provided by AirData reflect the recently updated AQI breakpoints. For a fact sheet on the revised PM2.5 standards and updated AQI breakpoints, visit: http://www.epa.gov/airquality/particlepollution/2012/decfsstandards.pdf
