Particulate Matter
epa.gov: PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope.

Air Quality Index
Air Quality Index (AQI) is used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. Public health risks increase as the AQI rises. More info: Wikipedia
The US Air Quality Index (AQI) is EPA’s tool for communicating about outdoor air quality and health. The AQI includes six color-coded categories.
AirNow: Every day the Air Quality Index (AQI) tells you how clean or polluted your outdoor air is, along with associated health effects that may be of concern. The AQI translates air quality data into numbers and colors that help people understand when to take action to protect their health.
Air Quality Advisory
An Air Quality Advisory (or Air Quality Alert) is an official notice issued by environmental or meteorological agencies when air pollution reaches or is forecast to reach unhealthy levels. It serves as a health warning, particularly for sensitive groups, and often advises the public to reduce strenuous outdoor activities. These advisories are based on the Air Quality Index (AQI), which measures five major pollutants regulated by the EPA: ground-level ozone, particle pollution (such as dust or wildfire smoke), carbon monoxide, sulfur dioxide, and nitrogen dioxide.
The alerts are typically color-coded to indicate severity:
- Yellow/Orange (AQI 101–150): Unhealthy for Sensitive Groups (e.g., children, the elderly, individuals with asthma or heart/lung conditions).
- Red (AQI 151–200): Unhealthy for everyone; sensitive groups should avoid all outdoor exertion.
- Purple/Maroon (AQI 201+): Very Unhealthy to Hazardous.
