Deán Funes, nestled within the province of Córdoba, Argentina, occupies a geographically significant position within the Pampas region. Located approximately 17 kilometers northwest of Córdoba City, it benefits from proximity to the provincial capital while maintaining a distinct, more rural character. The city’s coordinates (-30.4333, -64.3500) place it within a relatively flat terrain, typical of the fertile plains that define the Pampas. Elevation is modest, averaging around 550 meters above sea level, contributing to a generally stable atmospheric layer, though susceptible to temperature inversions under specific conditions. The surrounding landscape is predominantly agricultural, characterized by expansive fields of wheat, corn, and soybeans – a crucial element in the regional economy. This agricultural activity, while vital, can contribute to particulate matter pollution, particularly during harvest seasons. To the east lies Córdoba City, an urban hub with associated industrial zones and vehicular traffic, influencing Deán Funes’ air quality through prevailing winds. The urban–rural gradient is noticeable; Deán Funes exhibits a blend of residential areas and agricultural land, with a gradual transition towards more intensive farming further afield. The lack of significant natural barriers, such as mountains, allows for relatively unimpeded air movement, which can both disperse pollutants and transport them from nearby sources. The Río Suquía, though not directly adjacent, influences local microclimates and humidity levels, potentially affecting the behaviour of airborne particles. The city’s growth is linked to Córdoba’s expansion, creating a complex interplay between urban and agricultural influences on its environmental quality.

Deán Funes experiences a temperate climate with distinct seasonal variations that significantly impact air quality. Spring (September-November) generally sees improved conditions as winds increase, dispersing accumulated pollutants from winter. However, agricultural activities, including fertilizer application and pesticide spraying, can introduce localized spikes in particulate matter and volatile organic compounds. Summer (December-February) is typically drier, with higher temperatures and a greater propensity for temperature inversions, particularly during still nights. These inversions trap pollutants near the ground, potentially leading to periods of reduced visibility and elevated concentrations of certain gases. Avoiding strenuous outdoor activity during these stagnant periods is advisable, especially for children and the elderly. Autumn (March-May) brings cooler temperatures and increased rainfall, which helps to cleanse the atmosphere. However, harvest season coincides with this period, releasing dust and agricultural emissions. Winter (June-August) often presents the most challenging air quality conditions. Cold, stable air masses and frequent fog events contribute to pollutant accumulation. Temperature inversions are common, and wind speeds are generally low, hindering dispersion. Sensitive individuals, including those with respiratory conditions, should limit prolonged outdoor exposure during these months. The interplay of these seasonal factors, combined with agricultural practices and proximity to Córdoba City, creates a dynamic air quality profile throughout the year. Monitoring local weather patterns and agricultural activity is crucial for anticipating and mitigating potential air pollution episodes.
