Kottūru, nestled in the Shimoga district of Karnataka, India, occupies a geographically significant position within the Deccan Plateau. Located at approximately 14.83° N latitude and 76.23° E longitude, the town’s elevation averages around 600 meters above sea level, contributing to a relatively cool climate compared to lower-lying regions of Karnataka. The surrounding landscape is characterized by a mix of undulating hills, dense deciduous forests, and agricultural fields, typical of the Malnad region. Kottūru sits on the fringes of a gradual urban-rural gradient, transitioning from the denser settlements of Shimoga city to the more dispersed agricultural communities of the interior. The Tungabhadra River, though not directly adjacent, influences the regional hydrology and contributes to the area’s overall climate. The town’s proximity to the Western Ghats, while providing a scenic backdrop, also means it can be susceptible to moisture-laden winds and occasional fog, impacting atmospheric mixing. While Kottūru itself is a relatively small town, its location within a developing region means it’s increasingly influenced by industrial activity in nearby Shimoga and the surrounding agricultural belt, which utilizes fertilizers and pesticides. This interplay of natural features and burgeoning human activity shapes the local air quality profile, with potential for both natural and anthropogenic pollution sources. The terrain, with its gentle slopes, can sometimes trap pollutants, particularly during periods of low wind speed, exacerbating localized air quality issues. The surrounding forests, however, also act as a natural carbon sink, partially offsetting some of the pollution.

Kottūru experiences a distinct tropical wet and dry climate, significantly influencing its air quality throughout the year. The dry season, typically spanning from March to May, often sees a noticeable increase in particulate matter. This is due to a combination of factors: reduced rainfall leading to less atmospheric cleansing, increased dust from agricultural activities like tilling and harvesting, and stagnant air conditions caused by temperature inversions, where cooler air is trapped beneath a layer of warmer air, preventing vertical mixing. The monsoon season, from June to September, brings relief with frequent rainfall, effectively washing pollutants from the atmosphere and significantly improving air quality. However, heavy rainfall can also lead to increased soil erosion and runoff, potentially carrying particulate matter into the air. October and November mark a transitional period, with decreasing rainfall and gradually increasing temperatures. Fog, common during these months, can trap pollutants near the ground, leading to temporary episodes of reduced visibility and poorer air quality. December and January are generally cooler and drier, with relatively stable air quality, although occasional dust storms can impact conditions. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season and periods of fog, limiting outdoor exertion and ensuring adequate ventilation. Agricultural workers should prioritize protective measures like masks during peak farming activities. Maintaining green spaces and promoting sustainable agricultural practices are crucial for mitigating seasonal air quality fluctuations.
