AirNow Daily Air Quality Monitor

Return current or recent U.S. AirNow monitoring observations for environmental operations, reporting, and research teams. Filter by date, pollutant, and reported AQI with a hard output bound.

Try this first

{"date":"yesterday","pollutants":["PM2.5-24hr"],"maxResults":10}

Source: AirNow daily data, published through the official AirNow file service. Measurements can be preliminary and delayed; AQI values and categories are reported observations, not health advice or local agency forecasts. Limits: today or seven-day history, six pollutant names, 500 rows, and a 5 MB file gate, with retries and U.S.-only filtering.

Configuration

Use yesterday (the completed UTC day) for daily averages. The today file can lack PM2.5-24hr values until the day is complete. Explicit today and recent ISO dates remain supported. Filter pollutant names exactly as published. maxResults bounds returned monitoring records, not the size of the source file.

Input	Meaning
date	yesterday (default), today (possibly incomplete), or an ISO date from the last seven days.
pollutants	Optional parameter names such as PM2.5-24hr or OZONE-8hr.
minAqi	Optional minimum reported AQI.
maxResults	Hard output limit.

Empty results and troubleshooting

Daily files can lag collection. A missing file is reported as a source failure. No matching records or AQI values must not be interpreted as clean air. Recheck the reporting date and official local observations.

For support, open the Actor’s Issues tab with the input filters, error code and run ID. Remove tokens and private information. Do not publish credentials or patient/contact data.
