AirData
Tile Plot
Plot daily AQI values for a specific location and time period. Each square or “tile” represents one day of the year and is color-coded based on the AQI level for that day. The legend tallies the number of days in each AQI category.
Note: All PM2.5 AQI values and summaries provided by AirData are based on the current Air Quality Index in which the AQI 100 level is equivalent to 40 micrograms per cubic meter. Summaries from other sources may use 35 micrograms per cubic meter which is the level of the 24-hour PM2.5 standard.
