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.
Over the last 326 days with data, the mean daily PM2.5 in Chișinău was 9.1 µg/m³ — 1.8 times the WHO annual guideline (5 µg/m³). Over the last 30 days: 7.4 µg/m³. From Atmy's archive of daily city means.
In Atmy's daily archive, the cleanest month of the last year was July 2026: 3.8 µg/m³ on average.
The most polluted month of the last year was January 2026: 18.5 µg/m³ on average.
From November to March the mean daily PM2.5 was 13.9 µg/m³, from June to August 4.3 µg/m³ (last 365 days).
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.
