Us aqi index

How is AQI calculated? What are the three levels of quality? The AQI is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. Use the query tool below to get AQI reports for one state, county, or CBSA at a time.

The GAIA air quality monitoring stations are using high-tech laser particle sensors to measure in real-time PM2. Very easy to set up, they only require a WIFI access point and a USB power supply. Keep track of the most polluted cities in the world with our air quality index ( AQI ) ranking.

Concentration to AQI Select a Pollutant PM2. Click this link if you want a national file. The rank above might not be a complete list.

As part of this initiative, U. Mission Thailand is reporting the U. These data are captured by monitors owned and maintained by the Royal Thai government. The air quality data collected by the U. Environmental Protection Agency’s (EPA) NowCast algorithm. AQI) value that can help inform health-related decisions. This algorithm converts raw PM 2. Users can downloa output, view or visualize the data.

For example, if the PM2. AQI is 12 the PMAQI is 5 SOis 3 NOx is 5 and all other pollutants are less than 12 then the AQI is 125–determined ONLY by the concentration of PM2. Health Effects Statement PM2. Unusually sensitive people should consider limiting prolonged outdoor exertion. Air quality and pollen information for over 1countries in the world.

Air Quality Index ( AQI ) PM2. Taken together, concentration and time represent the dose of the air pollutant. EPA has developed a formula to convert PM 2. AQI ) value that can be of assistance in making health-related decisions. The index is calculated based on data over a 3-hour period depending on the variability of particulate concentration. Oregon’s index is based on three pollutants regulated by the federal Clean Air Act: ground-level ozone, particle pollution and nitrogen dioxide.

The starting point for graphical digital government air quality guidance. The reported AQI corresponds to the concentration level of the pollutant with the highest index. The IQAir AirVisual platform emphasizes the US AQI, or displays this value more prominently in the platform’s user interface (UI), because the US AQI is globally well established and among the strictest air quality indexes. BreezoMeter created a new and uniform air quality index - the BreezoMeter AQI , BAQI, that provides a clear and intuitive way to read and understand real-time air quality information. Discover the most accurate information on air quality today, using our air quality index map to find air quality anywhere in the world.
