Live AQI & Weather Monitor (Indian Cities)

Formula & Calculation Methodology

AQI categorization follows Central Pollution Control Board (CPCB India) PM2.5 guidelines: 0-30 Good, 31-60 Satisfactory, 61-90 Moderate, 91-120 Poor, 121-250 Very Poor, 250+ Severe.

AQI_{CPCB} = f(PM_{2.5}, PM_{10}, NO_2, O_3)

Step-by-Step Worked Example

Location: Delhi NCR | Current PM2.5: 84 µg/m³

1. Pollutant PM2.5 Concentration: 84 µg/m³
2. CPCB India Bracket: 61 - 90 µg/m³
3. Resulting Category: Moderate AQI
4. Health Advisory: Breathing discomfort possible for sensitive individuals.

Understanding Indian CPCB Air Quality Index

Air quality is monitored using real-time atmospheric sensor data measuring PM2.5, PM10, nitrogen dioxide, and ground-level ozone across major Indian metropolitan districts.
