Elankūr, nestled in the southern Indian state of Kerala, occupies a geographically significant position within the Malabar region. Located at approximately 11.1333° N latitude and 76.1667° E longitude, the town’s terrain is characterized by undulating hills and valleys, typical of Kerala’s Western Ghats foothills. The elevation, though modest, contributes to localized microclimates and influences air circulation patterns. Elankūr benefits from proximity to the Arabian Sea, approximately 20 kilometers to the west, which moderates temperatures and introduces maritime influences on air quality. The surrounding landscape is predominantly rural, a patchwork of lush rice paddies, coconut groves, and small-scale spice plantations – cardamom, pepper, and cloves are common. This agricultural zone, while generally beneficial, can contribute to localized emissions from agricultural practices, particularly during harvest seasons. To the east, the terrain gradually ascends towards the Western Ghats, a significant barrier impacting regional wind patterns and potentially trapping pollutants. The urban–rural gradient around Elankūr is relatively smooth; the town itself is small, with a population of just over 17,500, and blends seamlessly into the surrounding agricultural landscape. There are no major industrial belts immediately adjacent to Elankūr, however, larger industrial areas in nearby cities like Calicut can occasionally influence regional air quality through long-range transport of pollutants. The prevailing winds, generally southwesterly, bring moisture and influence the dispersion of any locally generated emissions.

Elankūr’s tropical climate dictates a distinct wet and dry season cycle, profoundly impacting its air quality. The southwest monsoon, typically spanning from June to September, brings abundant rainfall, effectively cleansing the atmosphere and significantly reducing particulate matter. This period generally offers the best air quality for outdoor activities. However, the monsoon can also introduce humidity, which can exacerbate respiratory issues for sensitive individuals. The dry season, from October to May, presents a different set of challenges. During these months, particularly November to February, cooler temperatures and calmer winds can lead to temperature inversions, trapping pollutants closer to the ground. Fog is also common during this period, further reducing visibility and concentrating pollutants. Agricultural burning, a common practice in surrounding areas to clear fields after harvest, peaks during late October and November, contributing to elevated levels of smoke and particulate matter. March to May sees a gradual increase in temperature and wind speeds, which helps to disperse pollutants, but dust from agricultural activities can still be a concern. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the dry season, particularly during periods of fog or agricultural burning. Avoiding strenuous outdoor activity during these times and ensuring adequate ventilation indoors are recommended. The monsoon months offer a respite, but awareness of humidity-related respiratory issues remains important.
