:dash: EPA Air Quality Index (AQI) Tracker

Current air quality data for every EPA reporting area in the United States from AirNow. Tracks AQI values for Ozone, PM2.5, and PM10 across hundreds of monitoring stations, updated hourly.

What data does it extract?

For each air quality observation, the Actor extracts:

Field	Description
Reporting Area	Geographic area name (e.g., "Los Angeles-South Coast Air Basin")
State	US state code
AQI	Air Quality Index value (0-500)
Category	AQI category (Good, Moderate, Unhealthy, etc.)
Parameter	Pollutant measured (OZONE, PM2.5, PM10)
Coordinates	Latitude and longitude of the reporting area
Date/Time	Date and hour of the observation
Agency	Reporting agency name
