Kūhbil, nestled within the Nīnawá Governorate of Iraq, occupies a geographically significant position within the broader Mesopotamian plain. Located at approximately 36.5169° N, 41.9605° E, the city’s terrain is predominantly flat, characteristic of the alluvial plains formed by the Tigris River, which flows relatively nearby. The surrounding landscape is a mix of agricultural land – primarily wheat and barley cultivation – and arid steppe, gradually transitioning into more rugged terrain further east towards the foothills of the Zagros Mountains. This proximity to both agricultural zones and a potential source of dust from the mountains significantly influences Kūhbil’s air quality. The urban character is that of a small, primarily rural settlement, with limited industrial activity, though agricultural machinery and practices contribute to localized emissions. The urban–rural gradient is sharp; Kūhbil blends seamlessly into the surrounding agricultural landscape, with minimal distinct urban sprawl. Elevation is relatively low, averaging around 250 meters above sea level, which can exacerbate the trapping of pollutants, particularly during periods of temperature inversion. The lack of significant natural barriers and the flat topography mean that winds, while sometimes providing some dispersion, can also carry pollutants from distant sources, including potential industrial areas further north within the governorate. The region's history of conflict and displacement has also impacted land use and potentially contributed to localized environmental degradation, further affecting air quality.

Kūhbil’s air quality experiences a distinct seasonal cycle dictated by its arid climate and prevailing meteorological patterns. The dry season, spanning roughly from May to September, is characterized by intense heat, minimal rainfall, and frequent dust storms originating from the surrounding deserts and the wider Mesopotamian plain. These storms, often exacerbated by agricultural practices like tillage, significantly elevate particulate matter concentrations. Temperature inversions, common during calm nights in summer, trap pollutants close to the ground, worsening air quality. Conversely, the cooler, wetter months (October to April) generally see improved air quality due to increased rainfall, which washes pollutants from the atmosphere, and reduced dust storm activity. However, periods of fog, particularly in late autumn and early spring, can also lead to localized pollution build-up. March and April often present a transitional period where dust storms can still occur alongside increased humidity, creating complex air quality conditions. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, limiting outdoor activity during peak dust storm periods and avoiding strenuous exertion. The agricultural cycle, with planting and harvesting activities, also contributes to seasonal variations, with increased emissions during these periods. Maintaining indoor air quality through proper ventilation and air filtration is particularly important during the dust storm season.
