Outdoor
Outdoor activity is generally possible, but conditions are not ideal.
Why: AQI or pollutant levels are elevated, so this guidance is more cautious.

Practical guidance
Running
Outdoor running is generally fine. If you are sensitive to air pollution, consider keeping the effort easy.
Why: Air quality indicators are elevated, so the running guidance is more cautious.
Ventilation
Consider waiting before longer ventilation.
Why: PM2.5, PM10, NO2 or ozone is elevated, so longer ventilation may bring more outdoor pollution indoors.

What affects air quality in New York
New York City's NYCCAS program studies how traffic, building boilers and furnaces, and other sources affect air-quality differences among NYC neighborhoods.
This describes long-running neighborhood source research, not current conditions in every neighborhood or the provenance of this page's current AQI.
Local monitoring and context
NYCCAS takes seasonal air-pollution measurements at varied New York City locations, including residential, commercial and industrial areas and sites near potential high-emission locations.
The survey samples selected locations and does not claim that one monitor represents all of New York City or supplies this page's current AQI.
City air quality FAQ
How should I read the AQI for New York?
US AQI condenses air quality into one value. On this page, it helps you quickly judge whether conditions look good, moderate or more polluted than usual.
Is the air quality good for going outside?
Check the outdoor and running cards first. They combine AQI, particles, ozone, weather and other factors that can affect outdoor comfort.
Should I ventilate right now?
The ventilation card considers AQI and pollutants such as particles, nitrogen dioxide and ozone. If values are elevated, a shorter opening or a later moment may be better.
Why can air quality change during the day?
Weather, emissions, ozone formation, particles and air flow can shift local conditions, so the next hours can differ from the current reading.
