Huilong in China reflects the flat Henan agricultural and urban corridor position, with vehicle traffic on surrounding roads and agricultural processing and manufacturing contributing local sources. Winter residential coal and biomass burning generates elevated PM2.5 under inversions, while the flat North China terrain allows reasonable summer dispersal and the regional industrial background elevates winter readings throughout the year.

When is air pollution at its worst in Huilong?
Air quality in Huilong tends to be worse when vehicle traffic, light manufacturing, and farming and agricultural processing build up and dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Huilong 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.
