Sangamner, nestled in the Ahmednagar district of Maharashtra, India, occupies a geographically significant position within the Deccan Plateau. Located at approximately 19.5678° N latitude and 74.2115° E longitude, the town sits at an elevation of around 610 meters (2000 feet) above sea level, contributing to a generally cooler climate compared to coastal Maharashtra. The surrounding landscape is characterized by undulating hills and plains, typical of the plateau region, with agricultural fields dominating the immediate periphery. This proximity to farmland, while supporting the local economy, introduces agricultural emissions, particularly during harvest seasons. Sangamner’s location is not directly adjacent to major rivers or lakes, though seasonal streams and smaller water bodies exist, influencing local humidity and microclimates. The town’s urban character is that of a regional market town, serving a predominantly rural hinterland. It’s situated within a gradual urban–rural gradient, with smaller villages and agricultural settlements extending outwards. Further afield, the industrial belt around Pune and Nashik exerts some influence, though Sangamner itself has limited large-scale industrial activity. The terrain, with its gentle slopes and relatively enclosed valleys, can sometimes trap pollutants, especially during periods of low wind speed. The prevailing winds, generally from the west, carry air masses across the plateau, potentially bringing in pollutants from distant sources, while also dispersing local emissions. The geological composition of the Deccan Traps, basaltic rock formations, also influences the local dust levels and particulate matter.

Sangamner’s air quality experiences a distinct seasonal cycle dictated by the region’s monsoon climate. The dry season, spanning roughly October to May, typically sees a gradual increase in pollution levels. During the cooler months (November to February), temperature inversions frequently occur, trapping pollutants close to the ground, particularly in the mornings. Agricultural burning, a common practice for clearing fields after harvest, significantly contributes to particulate matter during this period, peaking around November and December. March and April witness rising temperatures and increased dust due to wind activity and construction. The onset of the monsoon season (June to September) brings a dramatic improvement in air quality as rainfall washes away pollutants and strong winds disperse them. However, the initial monsoon phase can sometimes experience elevated humidity and localized fog, which can temporarily reduce visibility and trap pollutants. The summer months (April-May) are generally hot and dry, with dust storms occasionally impacting air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly during periods of agricultural burning. Outdoor activities are generally best enjoyed during the monsoon months, although heavy rainfall can still pose challenges. The transition periods – late September/early October and March/April – often see fluctuating air quality, requiring vigilance and awareness of local conditions. Maintaining indoor air quality through ventilation and air purification can be beneficial during periods of elevated pollution.
