METEOROLOGY – AIR QUALITY & ATMOPHERIC CHEMITRY CALCULATOR
Aqi Pollutant
A precise tool.
What is the Aqi Pollutant & How does it work?
The Air Quality Index (AQI) is a scale used to communicate the quality of air on a given day. It helps people understand what local air pollution levels mean for their health.
AQI values range from 0 to 500, where 0 indicates good air quality and 500 represents hazardous air quality. The AQI is calculated based on the concentration of pollutants in the air, such as particulate matter (PM2.5), ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and lead (Pb).
AQI = frac{text{Index}_i – text{Index}_{i-1}}{text{Concentration}_i – text{Concentration}_{i-1}} times (C – text{Concentration}_{i-1}) + text{Index}_{i-1}
AQI = Air Quality Index
C = Concentration of pollutant
Index}_i, text{Index}_{i-1} = AQI breakpoints for concentration ranges
Concentration}_i, text{Concentration}_{i-1} = Pollutant concentration breakpoints
C = Concentration of pollutant
Index}_i, text{Index}_{i-1} = AQI breakpoints for concentration ranges
Concentration}_i, text{Concentration}_{i-1} = Pollutant concentration breakpoints

Frequently Asked Questions
What does AQI stand for?
AQI stands for Air Quality Index, a scale used to measure the quality of air.
How is AQI calculated?
AQI is calculated based on the concentration of pollutants like PM2.5, ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead in the air.
What does an AQI value of 0 mean?
An AQI value of 0 indicates that the air quality is good, with little to no pollution affecting health.
What does a high AQI value indicate?
A high AQI value indicates poor air quality, which can be harmful to human health and may require precautions like staying indoors or wearing masks.
Which pollutants are considered in the AQI calculation?
The AQI considers pollutants such as particulate matter (PM2.5), ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and lead (Pb).
How can I improve my AQI?
To improve your AQI, reduce pollution sources like vehicle emissions, use cleaner energy, plant trees, and avoid burning materials that release pollutants.
Is there an app to check AQI in real-time?
Yes, many apps are available for checking the AQI in real-time. You can search for 'AQI monitor' or similar terms in your app store.
