Sherobod, nestled within Uzbekistan’s Surxondaryo Region, occupies a geographically significant position in the southern part of the country, close to the border with Afghanistan. Located at coordinates 37.6667° N, 67.0000° E, the city sits within the foothills of the Pamir-Alay mountain range, at an elevation of approximately 900 meters. This terrain profoundly influences local air quality. The surrounding landscape is characterised by arid and semi-arid conditions, with sparse vegetation cover, contributing to dust and particulate matter in the air, particularly during drier periods. The Sherobod district is largely agricultural, with cotton farming being a dominant land use. While not heavily industrialised itself, the region experiences some industrial activity related to agricultural processing and limited mining further afield. The city’s position within a valley can exacerbate pollution episodes, trapping pollutants during temperature inversions. The urban-rural gradient is relatively sharp; Sherobod is a comparatively small city surrounded by rural agricultural lands and mountainous terrain. The lack of significant water bodies nearby means limited natural dispersion of pollutants. The prevailing winds, often channeling through the valleys, can transport pollutants from surrounding areas into Sherobod, impacting air quality.

Sherobod experiences a continental climate with distinct seasons, each impacting air quality differently. Spring (March-May) sees increasing agricultural activity, including land preparation and potential burning of crop residue, leading to elevated particulate matter. Winds can be erratic, sometimes dispersing pollutants, other times concentrating them. Summers (June-August) are hot and dry, with minimal rainfall. This dryness exacerbates dust storms, significantly degrading air quality. Temperature inversions can occur, trapping pollutants near the ground. Autumn (September-November) is generally the clearest period, with cooler temperatures and some rainfall helping to settle dust. However, the post-harvest burning of agricultural waste again contributes to localised pollution spikes. Winter (December-February) brings cold temperatures and often stagnant air masses. Heating using coal and wood, common in residential areas, becomes a major source of particulate matter and sulfur dioxide. Sensitive groups, including children, the elderly, and those with respiratory conditions, should limit outdoor exposure during winter months and periods of high agricultural burning. Avoiding outdoor activity during calm, cold days in winter and during peak agricultural burning in spring and autumn is advisable. Monitoring local conditions is crucial.
