Real-Time Atmospheric Intelligence
TrueAQI is an open, high-frequency atmospheric intelligence platform designed to deliver transparent, calibrated air quality and meteorological data to millions of people worldwide.
Calibrated optical and gravimetric sensors measuring PM2.5, PM10, NO₂, and SO₂.
NASA FIRMS thermal anomaly detection and live RainViewer precipitation radar tiles.
Instant conversion between India NAQI (CPCB), US EPA, European CAQI, and China MEP.
Raw particulate measurements can be skewed by relative humidity, hygroscopic aerosol growth, and ambient temperature. TrueAQI applies dynamic humidity compensation algorithms to raw optical particle counter data, aligning local readings with regulatory reference instruments.
We also translate particulate mass concentration into an intuitive cigarette equivalence metric based on peer-reviewed epidemiological models (Berkeley Earth rule-of-thumb: 22 µg/m³ PM2.5 breathed over 24 hours ≈ 1 cigarette), empowering citizens with actionable health insights.
TrueAQI is built on modern web standards, leveraging Open-Meteo, NASA Earth Science Data, and local government air quality monitoring stations.
