As fire season continues, you may receive an air quality alert. But, what do these air quality alerts mean? Air quality is determined by the concentration of pollutants present in the air at a specific location. Exposure to air pollution can negatively impact our health, causing symptoms such as coughing, wheezing, and difficulty breathing. Air quality alerts help our communities take action to protect ourselves from air pollution. AirNow (airnow.gov) is the U.S. Environmental Protection Agency’s “one-stop shop” for air quality data. This website allows users to look up the official U.S. Air Quality Index (AQI) for their ZIP code, city, or state. The AQI ranges from 0 to 500 – the higher the AQI value is, the greater the concentration of harmful air pollutants. The AQI is conveniently organized into categories that correspond to a level of risk, indicated by colors. Green indicates that air quality is healthy, whereas purple indicates that air pollution threatens the health and safety of all groups. AirNow also provides information on what steps to take at each AQI level to protect yourself and others, such as resting more or moving physical activity indoors. Maps of AQI are also available through the Apple weather app. OpenAQ (openaq.org), a partner of Project Phoenix, is a non-profit that amalgamates air quality data from reference monitors and low-cost air sensors around the world into an interactive global map. Users can explore several different pollutants and specify which sources of data to display. The map is color-coded so that darker colors signal higher levels of the selected pollutant. We always want Project Phoenix volunteers to be safe when conducting surveys. We urge our volunteers to take precautions when birding on smoky days and encourage wearing an N95 mask outdoors when air pollution is unhealthy. If you would like us to mail you N95 masks (free of charge) to use when conducting your surveys, please send us an email at projectphoenix.socal@gmail.com.
