Doranahalli, nestled in Karnataka, India, occupies a geographically significant position within the broader landscape of the Deccan Plateau. Located at approximately 16.7324° N, 76.9162° E, the city’s terrain is characterized by gently undulating hills and plains, typical of the region. Its elevation, while modest, contributes to localized microclimates that can influence air circulation patterns. Doranahalli sits within a predominantly rural setting, exhibiting a gradual urban–rural gradient as one moves outwards. The surrounding landscape is a mosaic of agricultural fields – primarily cultivating crops like rice, ragi, and maize – interspersed with patches of dry deciduous forests. This agricultural activity, while vital to the local economy, can contribute to seasonal particulate matter pollution, particularly during harvest periods when burning of crop residue is practiced. The city’s proximity to the Tungabhadra River, though not directly adjacent, influences regional humidity and precipitation patterns, impacting atmospheric stability and pollutant dispersion. Further afield, the industrial belt around Hubli-Dharwad, approximately 150 kilometers north, represents a potential source of long-range transported pollutants. The prevailing wind patterns, generally southwest to northeast, can carry pollutants from these industrial areas towards Doranahalli, especially during periods of lower wind speed. The relatively flat topography surrounding the city can also exacerbate the trapping of pollutants, particularly during temperature inversions, hindering effective dispersion and leading to localized air quality degradation. The urban character of Doranahalli is primarily residential, with limited commercial and industrial activity within the city limits itself, minimizing internal pollution sources.
Doranahalli’s tropical climate dictates a distinct wet and dry season cycle, profoundly impacting its air quality. The dry season, typically spanning from March to May, is often characterized by elevated particulate matter concentrations. This is due to a combination of factors: reduced rainfall leading to less atmospheric cleansing, increased dust from agricultural activities (plowing, harvesting), and the prevalence of temperature inversions. These inversions, where a layer of warm air traps cooler air near the ground, inhibit vertical mixing and effectively ‘cap’ pollutants, leading to their accumulation. The monsoon season, from June to September, brings relief through frequent rainfall, which naturally washes pollutants from the atmosphere. However, the onset of the monsoon can initially be accompanied by increased humidity and fog, which can temporarily trap pollutants, especially in the early weeks. October and November represent a transitional period, with decreasing rainfall and gradually increasing temperatures, potentially leading to a resurgence of particulate matter. December and January are generally cooler months, with occasional fog, which can again contribute to localized pollution episodes. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly during periods of stagnant air or fog. Limiting outdoor exertion and wearing appropriate masks can mitigate exposure. Agricultural workers should be mindful of dust exposure during field operations, and consider using protective gear. Public awareness campaigns promoting responsible agricultural practices, such as avoiding open burning of crop residue, are crucial for improving air quality throughout the year.
