Droue-sur-Drouette, November 10, 2026: daily mean PM2.5 17 µg/m³ (4 sensors), level “Moderate” — as in the Atmy Data Hub. Open methodology and data in JSON: Methodology and data sources · JSON
There are not enough fresh measurements for Droue-sur-Drouette right now. From 10:00 to 18:00 local time the city mean PM2.5 rose from 5.0 to 11.5 µg/m³.
Light wind (1 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). High humidity (100%) possibly makes optical sensors read somewhat higher.
Weather now: fog, 9°C, wind 1 m/s, humidity 100%. By 08:00 the wind is expected to pick up to 4 m/s, which may clear the air.

Fresh data for Droue-sur-Drouette are insufficient (last update: 20:45 local time, 19:45 UTC). Open the map for the latest readings of individual sensors.
From Atmy sensors and connected public networks (citizen, experimental and government monitors), aggregated by Atmy. Values are approximate; see the methodology.
The summary is rebuilt every 15 minutes from the latest reading of each sensor, each no older than one hour.
The daily value is the Data Hub’s: the mean of the city’s sensors that passed the nightly quality check, each with at least 12 valid hours, and only with sensors at four places 500 m apart; days are UTC.
“Now” uses the same sensors and rule: the mean of their latest readings, each at most 60 minutes old, shown only with sensors at four places 500 m apart reporting.
