Full FGDC metadata records for each layer may be found by clicking the layer name at the web service endpoint (available through the online link provided above) and viewing the layer description. This service is used to display the number of days fine particle pollution (PM2.5) reached “code orange” or above on the Air Quality Index (AQI) for PM2.5 for selected U.S. cities in 2014. An AQI of "code orange" is considered unhealthy for sensitive groups; "code red" is unhealthy for everyone.Fine particle pollution can be emitted directly from cars, trucks, buses, power plants and industries, along with wildfires and woodstoves. But it also forms from chemical reactions of other pollutants in the air. Particle pollution can be high at different times of year, depending on where you live. In some areas, for example, colder winters can lead to increased particle pollution emissions from woodstove use, and stagnant weather conditions with calm and light winds can trap PM2.5 pollution near emission sources. Federal and state rules are helping reduce fine particle pollution, including clean diesel rules for vehicles and fuels, and rules to reduce pollution from power plants, industries, locomotives, and marine vessels, among others.None.None.
