In Domnești the air is unhealthy for sensitive groups 🟠 AQI 122. About the same as three hours ago. ☁️ +9 °C · No precipitation · Wind 1 m/s
In Domnești the air is unhealthy for sensitive groups right now (approximate, US EPA scale). From 11:00 to 00:00 local time the city mean PM2.5 rose from 31.5 to 44.0 µg/m³. The highest hour was 21:00 with 56.0 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 (92%) possibly makes optical sensors read somewhat higher.
Weather now: cloudy, 9°C, wind 1 m/s, humidity 92%. Precipitation is expected around 01:00; it may wash particles out. By 11:00 the temperature will be about 14°C.

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.
