This US EPA feature layer is updated hourly and reflects the latest hour of air quality data received from each monitoring site that reports to AirNow. The concentration and AQI values are for Ozone and Particulate Matter (PM) only. Air … Continued
This layer displays the percentage of days with concentrations of ozone matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter.
Layer displays the modeled cancer risk associated with air toxics exposure. Figures represents the likelihood of hazardous exposure per 1 million population.
This indicator describes trends in average surface temperature for the United States. Indicator data are acquired from the EPA’s Climate Change Indicators in the United States, Fourth Edition, published in 2016.
This indicator examines changes in the size and frequency of inland river flood events in the United States. Indicator data are acquired from the EPA’s Climate Change Indicators in the United States, Fourth Edition, published in 2016.
