Corenc, November 10, 2026: daily mean PM2.5 6 µg/m³ (8 sensors), level “Low” — as in the Atmy Data Hub. Open methodology and data in JSON: Methodology and data sources · JSON
In Corenc the air is moderate right now (approximate, US EPA scale). From 10:00 to 20:00 local time the city mean PM2.5 stayed roughly level: from 9.5 to 9.3 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).
Weather now: cloudy, 14°C, wind 1 m/s, humidity 77%. Precipitation is expected around 06:00; it may wash particles out. By 10:00 the temperature will be about 11°C.

Daily mean PM2.5 on November 10, 2026 (00:00–24:00 UTC = 01:00–01:00 UTC+1): 6 µg/m³ from 8 sensors that passed the quality check — the same value as in the Atmy Data Hub.
Fresh data for Corenc are insufficient (last update: 21:45 local time, 20:45 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.
