Lille, November 10, 2026: daily mean PM2.5 22 µg/m³ (4 sensors), level “Moderate” — as in the Atmy Data Hub. Open methodology and data in JSON: Methodology and data sources · JSON

In Lille the air is moderate right now (approximate, US EPA scale). From 10:00 to 21:00 local time the city mean PM2.5 rose from 15.0 to 19.7 µg/m³.

Light wind (2 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). High humidity (95%) possibly makes optical sensors read somewhat higher.

Weather now: cloudy, 6°C, wind 2 m/s, humidity 95%. No major change in the wind is expected in the coming hours.

Written automatically at 22:09 local time (21:09 UTC) from sensor measurements and the weather forecast. Values are approximate; hypotheses are marked.
