Zhengzhou, November 10, 2026: daily mean PM2.5 34 µg/m³ (10 sensors), level “Moderate” — as in the Atmy Data Hub. Now (06:00 local time): 64.4 µg/m³. Open methodology and data in JSON: Methodology and data sources · JSON

Right now in Zhengzhou, PM2.5 averages 64.4 µg/m³ — “unhealthy” on the US EPA scale (approximate, from hourly readings). Mean of 10 sensors from Government stations, readings from 05:00–05:00 local time (21:00–21:00 UTC), summary prepared at 06:00 local time. Median: 61.5 µg/m³; range across sensors: 51.0–86.0 µg/m³.

In Zhengzhou the air is unhealthy 🔴 AQI 157. About the same as three hours ago. ⛅ +7 °C · No precipitation · Wind 2 m/s

In Zhengzhou the air is unhealthy right now (approximate, US EPA scale). From 17:00 to 06:00 local time the city mean PM2.5 rose from 52.6 to 64.4 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 (93%) possibly makes optical sensors read somewhat higher.

Weather now: partly cloudy, 7°C, wind 2 m/s, humidity 93%. No major change in the wind is expected in the coming hours. By 17:00 the temperature will be about 15°C.

Data

Where do these data come from?

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.
