Why CERNS.IO is different

Hybrid data, honestly weighted
Ground station readings cross-checked against CAMS satellite model. Each source corrects the other — you see the reconciled picture, not a single sensor's guess.
WHO limits, not just color bands
AQI 150 means roughly 4× the WHO annual safe limit. We show that number. You decide what the risk means to you — we don't abstract it away.
Weather and AQI together
72-hour forecasts for AQI, PM2.5, temperature, rain, and UV in one view. Wind drives smoke — you need both to understand what is coming.
