Air Quality Monitoring Across North America: Current Data and Tools
AirNow provides a centralized platform for accessing air quality data across the United States, Canada, and Mexico. The platform offers real-time air quality information, including the Air Quality Index (AQI) for pollutants such as ozone and particulate matter (PM). The interactive map on AirNow highlights the highest pollutant levels in a given area, offering users a clear view of current conditions. However, it is important to note that the data presented is preliminary and subject to validation. The platform also includes resources to understand AQI basics and NowCast AQI, which provides near real-time air quality updates. This service is designed to help individuals and communities make informed decisions about outdoor activities based on air quality conditions.
