Česká Třebová, nestled within the Pardubický Kraj of the Czech Republic, occupies a strategic position in the rolling hills of Bohemia. Situated at coordinates 49.9019, 16.4472, the town’s geography is defined by its location within the Svitavy Ridge, a landscape characterized by gentle slopes and forested areas. The elevation, averaging around 280 meters above sea level, contributes to localized meteorological conditions. The town is bisected by the Svitava River, a tributary of the Elbe, which provides a natural corridor and influences local humidity. Česká Třebová isn’t heavily industrialized itself, but lies within a region historically linked to agriculture and light manufacturing, with larger industrial centres like Pardubice nearby. This proximity means the town can experience pollutant transport from these sources. The urban-rural gradient is relatively sharp; the town quickly transitions to agricultural land and forested hills, impacting dispersion patterns. The prevailing winds, often from the west and southwest, can carry pollutants from these areas, while the hilly terrain can create pockets of stagnant air, exacerbating localized pollution events. The town’s compact layout, typical of many Central European settlements, also influences air circulation.

Air quality in Česká Třebová exhibits a distinct seasonal pattern. Winter, from November to February, typically sees the poorest air quality. Low temperatures create temperature inversions, trapping pollutants near the ground, and increased reliance on solid fuel heating – coal and wood – for residential warmth significantly elevates particulate matter (PM) concentrations. Fog, common during these months, further reduces dispersion. Spring, March to May, brings gradual improvement as temperatures rise and heating demand decreases, though agricultural activities can contribute to ammonia levels. Summer, June to August, generally offers the cleanest air, aided by higher temperatures, stronger winds, and increased vegetation cover which absorbs pollutants. However, occasional heatwaves can lead to ozone formation. Autumn, September to October, sees a return to poorer conditions as heating systems are reactivated and atmospheric stability increases. Sensitive individuals – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during winter and autumn months. Monitoring pollen levels is also crucial in spring. The months of June, July, and August are generally most favourable for outdoor pursuits, but even then, awareness of potential ozone spikes during heatwaves is advised.
