Kesarimangalam, nestled in the Tiruppur district of Tamil Nadu, India, occupies a geographically significant position within the Kaveri River basin. Located at approximately 11.5423° N latitude and 77.7247° E longitude, the town’s terrain is characterized by gently undulating plains, typical of the fertile delta region. The surrounding landscape is predominantly agricultural, with extensive rice paddies and coconut groves dominating the rural areas immediately adjacent to Kesarimangalam. This proximity to intensive agricultural practices contributes to localized air quality concerns, particularly related to biomass burning during harvest seasons. The town sits at a relatively low elevation, which can exacerbate the trapping of pollutants, especially during periods of temperature inversion. While not directly bordering a major river, the Kaveri’s influence is felt through the region’s groundwater resources and irrigation systems, supporting the agricultural economy. Kesarimangalam’s urban character is that of a small, developing town, transitioning from a primarily rural setting. The urban–rural gradient is gradual, with agricultural land gradually giving way to residential and commercial areas within the town limits. The region’s position within Tamil Nadu’s industrial belt, particularly the textile industry concentrated in Tiruppur, introduces a regional air pollution influence, with potential for transported pollutants impacting Kesarimangalam’s air quality. The prevailing winds, generally southwesterly, can carry pollutants from industrial zones to the town, depending on meteorological conditions.

Kesarimangalam’s tropical climate dictates a distinct wet and dry seasonal pattern, profoundly influencing its air quality. The dry season, typically spanning from March to May, often witnesses a noticeable increase in particulate matter. This is largely attributable to increased agricultural burning as farmers clear fields after the harvest, releasing significant quantities of smoke and ash into the atmosphere. Temperature inversions, common during these months, trap pollutants close to the ground, further worsening air quality. The monsoon season, from June to September, brings relief as rainfall washes away pollutants and strong winds disperse them. However, the onset of the monsoon can initially be accompanied by increased humidity and fog, which can temporarily reduce visibility and trap pollutants. October and November represent a transitional period, with decreasing rainfall and gradually increasing temperatures, potentially leading to a resurgence of agricultural burning. During the cooler months (December-February), while temperatures are relatively mild, fog can form, particularly in the mornings, creating stagnant air conditions that can concentrate pollutants. 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 considering the use of air purifiers indoors. Agricultural workers are particularly vulnerable and should utilize appropriate respiratory protection during burning activities.
