Głogów, nestled in the Dolnośląskie Voivodeship of Poland, occupies a strategically important position at the confluence of the Barycz and Prosna rivers, both tributaries of the Oder. Its coordinates (51.6589, 16.0803) place it within a relatively flat, alluvial plain, characteristic of the Lower Silesian region. The surrounding landscape is a mosaic of agricultural fields – predominantly grain and rapeseed – interspersed with pockets of woodland and wetlands, reflecting the fertile nature of the river valleys. Głogów’s terrain is gently undulating, with elevations rarely exceeding 120 meters above sea level, contributing to a tendency for pollutants to accumulate, particularly during periods of stable atmospheric conditions. Historically, the city’s location facilitated trade and transport along the Oder, and this legacy is evident in its urban layout. While primarily a residential and service-based city today, Głogów retains a connection to industrial activity, with some light manufacturing and processing industries present. The urban–rural gradient is relatively gradual, with agricultural land extending close to the city limits. This proximity to agricultural zones can contribute to seasonal particulate matter pollution from farming practices. Furthermore, Głogów’s position within the broader Oder River basin means it is susceptible to transboundary pollution events originating from upstream industrial areas, impacting air quality and requiring regional cooperation for effective mitigation. The flat topography and riverine setting combine to create a microclimate that can exacerbate air pollution episodes.

Głogów’s air quality experiences a distinct seasonal cycle heavily influenced by meteorological conditions. Winter months (November to February) often present the most challenging period. Cold temperatures and frequent temperature inversions trap pollutants near the ground, leading to increased concentrations of particulate matter and nitrogen oxides. Fog, common during these months, further restricts atmospheric mixing, worsening the situation. Spring (March to May) brings a gradual improvement as temperatures rise and wind speeds increase, dispersing pollutants. Agricultural activities, however, can introduce dust and ammonia into the air, particularly during ploughing and fertilizer application. Summer (June to August) generally offers the best air quality, with warm temperatures, frequent rainfall, and consistent winds promoting effective pollutant dispersion. However, heatwaves can lead to ozone formation, a secondary pollutant. Autumn (September to October) sees a return to more variable conditions. Cooler temperatures and decreasing daylight hours can lead to stagnant air, while agricultural burning, though regulated, can still contribute to particulate matter. The prevailing wind patterns, typically from the west and southwest, play a crucial role in determining the direction of pollutant transport. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during winter months and be mindful of agricultural activities in spring and autumn. Outdoor activities are generally best enjoyed during the summer months, avoiding peak traffic hours and areas with high industrial emissions.
