Gunnedah's valley location means still air and temperature inversions are common, particularly in winter, trapping wood-smoke and vehicle emissions close to the ground on cold nights. Agricultural dust from surrounding cropping land is a routine warm-season feature, especially during cultivation and harvest. Summer bushfire smoke from nearby forested ranges can also settle in the valley, making Gunnedah's air quality more variable than open plains towns nearby.

When is air pollution at its worst in Gunnedah?
The Namoi Valley's tendency to trap still air means Gunnedah's air quality is often worst during winter inversions, when wood-smoke lingers overnight, and during dry, dusty periods around cropping and harvest season. Summer bushfire smoke drifting from surrounding ranges can also settle in the valley rather than clearing quickly. Windy, rainy periods bring the best relief.
Are air quality levels in Gunnedah 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.
