Ağcabədi, nestled within the central plains of Azerbaijan, occupies a geographically significant position in the country’s agricultural heartland. Located at coordinates 40.0489, 47.4502, the city sits approximately 120 meters above sea level, characterized by a relatively flat terrain typical of the Kura-Araz Lowland. This lowland is a broad depression between the Greater and Lesser Caucasus mountains, influencing local wind patterns and contributing to potential temperature inversions. Ağcabədi is not directly adjacent to a major body of water, though the Kura River flows nearby, impacting regional humidity and occasionally contributing to localized fog formation. The surrounding landscape is dominated by extensive agricultural fields – primarily cotton, wheat, and barley – which, while economically vital, represent a significant source of particulate matter from soil disturbance and agricultural practices. The urban-rural gradient is sharp; Ağcabədi itself is a relatively small city, quickly transitioning to open farmland. The lack of substantial natural barriers to air flow means pollutants can accumulate, particularly during stable atmospheric conditions. Industrial activity is limited within the city itself, but regional industrial zones further east can contribute to background pollution levels, transported by prevailing winds. This combination of factors creates a unique air quality profile for Ağcabədi.

Ağcabədi’s air quality follows a distinct seasonal pattern, largely dictated by meteorological conditions and agricultural activity. Spring (March-May) sees a rise in particulate matter as land preparation for planting commences, with dust and soil erosion contributing to poorer air. Winds are often variable, sometimes failing to disperse pollutants effectively. Summer (June-August) typically offers the cleanest air, with higher temperatures and occasional rainfall helping to settle dust and disperse pollutants, though ozone formation can become a concern during prolonged hot, sunny periods. Autumn (September-November) is a critical period. The cotton harvest generates significant dust and biomass burning for residue disposal, leading to a substantial increase in PM2.5 and PM10. Temperature inversions become more frequent, trapping pollutants near the ground. Winter (December-February) brings stable, cold air masses and reduced wind speeds, exacerbating the effects of any existing pollution sources. Fog is common, further reducing visibility and trapping pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during autumn and winter. Spring can also pose risks due to pollen and dust. Monitoring wind direction and avoiding peak harvest times are advisable.
