AirAgora library
Air-pollutant explainers
Factual explainers for PM2.5, PM10, ground-level ozone, and nitrogen dioxide, with units, AQI context, modeled limits, and primary sources.
Understand what a field represents before comparing it. AirAgora keeps concentration units separate from index components and does not infer a city pollution source from one value.

Every page keeps sources, limitations, FAQs, and paths into the real tool.
What is ground-level ozone? Reading an hourly air-quality forecast
Learn how ground-level ozone appears in modeled forecasts and concentration-band context, why it is not the protective ozone layer, and how to interpret hourly changes.
Open page →What is nitrogen dioxide? Interpreting NO₂ forecast data
Learn what the NO₂ field means, how concentration differs from an concentration-band context, why grid forecasts vary from street readings, and how AirAgora uses it.
Open page →What is PM10? Understanding coarse-particle forecasts
A source-grounded explanation of PM10 concentration, its relationship to PM2.5, modeled grid limits, concentration-band context, and practical planning.
Open page →What is PM2.5? A practical guide to fine-particle forecasts
Understand PM2.5 units, modeled forecasts, concentration-band context, limits, and how to use fine-particle information without treating it as a street-level measurement.
