Composite score based on AQI level and pollutant concentrations. Higher = cleaner air. Combines multiple pollutant readings into a single quality metric.

Breathability Score (0-100)

Measures how comfortable outdoor air is for breathing. Factors in PM2.5, O3, and NO2 levels relative to health guidelines. Higher = easier breathing.
