Portability: Compact and lightweight, making it easy to store or carry for personal use
Simple Example Given: PM2.5 concentration = 20 g/m Breakpoints: BP Lo = 12.1, BP Hi = 35.4, I Lo = 51, I Hi = 100 Calculation: I = [(100 51) / (35.4 12.1)] (20 12.1) + 51 = [49 / 23.3] 7.9 + 51 67.6 Result: AQI 68 Category: Moderate Theory & Engineering Applications The Science Behind the Air Quality Index The AQI puts pollutant concentrations onto a common scale0 to 500by using piecewise linear interpolation between breakpoints set by the EPA
