What is the formula to calculate AQI?
Our air quality index is calculated based on averages of all pollutant concentrations measured in a full hour, a full 8 hours, or a full day. To calculate an hourly air quality index, we average at least 90 measured data points of pollution concentration from a full hour (e.g. between 09:00 AM and 10:00 AM).
How does EPA calculate AQI?
The daily ozone AQI is calculated by taking the maximum 8 hour concentration from 07:00-23:00 LST, and then converting to AQI. There are 17 8-hour averages considered in each day. Each 8-hour average requires 6 of 8 hours (75%) for a valid calculation.
What are the criteria pollutants to calculate AQI?
Eight individual pollutants are monitored for the calculation of AQI, namely, PM10, PM2. 5, nitrogen dioxide, sulphur dioxide, carbon monoxide, ground-level ozone, ammonia, and lead.
