Note that the prominent pollutant can vary from city to city. This reflects a PM2.5 concentration of about 135 microgram/m3. For example, if the individual pollutant index for PM2.5 is 90, nitrogen dioxide is 45 and ozone is 65, then the AQI will be 90, the value of the index for PM2.5. The Air Quality Index is based on data collected from DEQ's air monitors. From CPCB’s AQI website, it appears that CPCB calculates the AQI-equivalent for hourly concentrations, and reports the running average of these values for the previous 24 hours on its website, and Sameer app. As seen in the table below, the AQI is a numbered and color coded way to report the daily air quality. The map above updates regularly with the most up-to-date calculated Air Quality Index for Health (AQIH) for each station.. This web page provides the most current AQI and hourly averaged data available. The air quality objectives or standards that old air quality index uses in its calculations are based on a variety of factors including effects on human health, vegetation, and consideration of the technical and economic achievability of the objectives as air quality management goals. 3. if the 24-hour average concentration is 15 microgram/m3, the corresponding AQI is 25. Addressed to policy-makers as well as scientists engaged in air quality monitoring, the book responds to the failure of most monitoring systems to provide data that are useful in estimating and managing threats to health. The National Air Quality Index (AQI) in India was launched on 17 September 2014 in New Delhi under the Swachh Bharat Abhiyan by the Environment Minister Shri PrakashJavadekar. Computing the AQI. An AQI value is calculated for each individual pollutant using standard formulas. It can be used as a standard when comparing air quality in other cities around the world. In most cases, though, concentrations of PM2.5 drive the AQI values in Indian cities.

Comparing air quality conditions at different locations/cities. This United States Air Quality Index number is calculated using the levels of six of the most prolific air pollutants, which are nitrogen dioxide, sulfur dioxide, ozone, carbon monoxide and both sizes of particulate matter, being PM2.5 and PM10. For example, in the figure 3 below, the AQI reading is 298 (“Poor”) with the prominent pollutant as PM2.5. Enter your zip code into EPA’s Air Quality Index to find out conditions in your area. For example, values shown for the noon hour are based on measurements taken from noon to 1:00 p.m. For example, values shown for the noon hour are based on measurements taken from noon to 1:00 p.m. The highest sub-index for any given hour is recorded as the AQI for that hour. The Sameer app and its corresponding website, following the CPCB process, report a 24-hour average. AQI helps in analysing the change in air quality (improvement or degradation). These data are not formally verified by the countries. The AQI in Lane county is calculated for two major pollutants regulated by the Clean Air Act: ground-level ozone and particulate matter (PM2.5). It is severe (400+) if 24-hour averages are greater than 250 microgram/m3, and if concentrations are 380 microgram/m3 or more, they get reported as 500, the maximum possible. This interactive map displays the current AQI for all ambient air quality monitors in the state.

Finally, there are many other apps and web portals, andeach may report related but somewhat distinct figures. The air quality index (AQI) is an index for reporting air quality on a daily basis. The air quality objectives or standards that old air quality index uses in its calculations are based on a variety of factors including effects on human health, vegetation, and consideration of the technical and economic achievability of the objectives as air quality management goals. The highest of these AQI values are reported as the AQI value for that day. It is a measure of how air pollution affects one's health within a short time period. AQI calculations for the current day, as shown on the map and reports, use NowCast AQI calculations. On an hourly basis, the concentration of each pollutant in the air is measured and converted into a number running from zero upwards by using a standard index or scale. According to the Berkeley Earth science research group; breathing in air with a PM2.5 content of between 950 to 1,000 is like smoking 44 cigarettes a day. An AQI value is calculated for each individual pollutant using standard formulas. The quality of the air you breathe today can affect your health now and for many years to come. If a station is grey , there may be an instrument or communication issue associated with it or it may be undergoing planned maintenance/upgrade.. For ozone, it is the max 8-hour running average for the day. It is calculated for five of the six major criteria air pollutants regulated by the federal Clean Air Act: ground-level ozone, particle pollution, carbon monoxide, sulfur dioxide, and nitrogen dioxide.EPA established national ambient air quality standards for each pollutant to protect public health. By default, the air quality index depicts the situation 3 hours ago. Different countries use different point scales to report air quality. It shows the amount and types of gases dissolved in the air. Air Quality Index: Questions and misconceptions about the AQI. If a city has multiple monitors, the average across the city is used and reported in CPCB’s AQI bulletin (see figure 1 below).
