Daye's air quality reflects the Hubei eastern Yangtze River valley's copper mining and smelting position adjacent to Wuhan, with the Daye Nonferrous Metals complex generating elevated heavy metal PM2.5 and SO₂. The Yangtze valley provides limited ventilation, while winter inversions concentrate smelting and heating emissions and Daye maintains Hubei's most distinctively copper smelting-defined urban environment throughout the year.

Frequently Asked Questions
Is air quality bad in Daye right now?
On 16 July 2026, overall air quality in Daye is fair. SO2 is the main pollutant at 26.4/100. Pollution peaks around 4:00 PM (O3: 47.6/100).
Will air quality be worse tomorrow in Daye?
On 17 July 2026, air quality conditions in Daye will be similar to today, with O3 forecast at fair at 39.4/100. Pollution peaks around 10:00 PM (SO2: 42.0/100).
When is air pollution at its worst in Daye?
Pollution in Daye typically rises when mining operations, especially once calm, stagnant conditions settle in the surrounding valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Daye based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
