Right now in Luoyang, PM2.5 averages 66.8 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: 69.0 µg/m³; range across sensors: 38.0–83.0 µg/m³.
In Luoyang the air is unhealthy 🔴 AQI 159. About the same as three hours ago. ⛅ +5 °C · No precipitation · Wind 2 m/s
In Luoyang 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 41.1 to 66.8 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). Cold weather (5°C) possibly means more heating, a common source of particles.
Weather now: partly cloudy, 5°C, wind 2 m/s, humidity 96%. No major change in the wind is expected in the coming hours. By 17:00 the temperature will be about 16°C.
Written automatically at 06:00 local time (22:00 UTC) from sensor measurements and the weather forecast. Values are approximate; hypotheses are marked.

Daily mean PM2.5 on November 10, 2026 (00:00–24:00 UTC = 08:00–08:00 UTC+8): 31 µg/m³ from 10 sensors that passed the quality check — the same value as in the Atmy Data Hub. No. 85 of 100 cities in China and No. 159 of 676 worldwide, from the most polluted.
Right now in Luoyang, PM2.5 averages 66.8 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: 69.0 µg/m³; range across sensors: 38.0–83.0 µg/m³.
The current level is “unhealthy” (US EPA scale, approximate). Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it. This is the standard guidance of the scale, not medical advice.
Highest current reading: 83.0 µg/m³ (市委新办公区 (中国环境监测总站 (CNEMC) — 国家城市环境空气质量监测网)). Lowest: 38.0 µg/m³ (吉利监测站 (中国环境监测总站 (CNEMC) — 国家城市环境空气质量监测网)). The list shows every sensor, highest first.
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.
