Kottapeta, nestled in Andhra Pradesh, India (16.7167° N, 81.9000° E), presents a compelling case study in how regional geography shapes urban air quality. Situated approximately 60 kilometers southwest of Kurnool, the city’s terrain is characterized by undulating hills and valleys, typical of the Deccan Plateau. The elevation, averaging around 550 meters above sea level, contributes to a localized tendency for temperature inversions, particularly during cooler months, trapping pollutants closer to the ground. Kottapeta’s location within a predominantly agricultural belt means that seasonal agricultural burning, particularly after the harvest of crops like groundnut and maize, significantly impacts air quality. The surrounding landscape is a mosaic of dry deciduous forests and cultivated fields, with sparse vegetation cover limiting natural air filtration. While not directly adjacent to a major river, the region receives runoff from the Nallamala Hills, influencing local humidity and potentially affecting particulate matter deposition. The urban–rural gradient around Kottapeta is relatively sharp; the city itself is compact, but its air quality is inextricably linked to the agricultural practices and industrial activity (primarily small-scale stone quarries and agricultural processing units) in the surrounding rural areas. The lack of extensive green spaces within the city further exacerbates the challenges in maintaining clean air, making the local topography and land use patterns key determinants of air pollution levels.

Kottapeta’s tropical climate dictates a distinct seasonal pattern in air quality. The dry season, roughly from March to May, is typically the most challenging period. High temperatures and low humidity create stable atmospheric conditions, frequently leading to temperature inversions that trap pollutants. Agricultural burning intensifies during this period as farmers clear fields for the next planting season, releasing substantial amounts of particulate matter and gases. Dust storms, common during April and May, further degrade air quality. The monsoon season, from June to September, brings relief as increased rainfall and stronger winds disperse pollutants. However, heavy rainfall can also lead to increased humidity and the formation of ground-level ozone under certain conditions. October and November mark a transitional period, with decreasing rainfall and gradually increasing temperatures, often accompanied by fog, which can trap pollutants. December and January are generally the coolest months, and while temperatures are lower, the prevalence of fog and temperature inversions can lead to localized air quality deterioration. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season and periods of dense fog. Outdoor activities are best planned for the monsoon months when air quality is generally improved, although vigilance regarding ozone levels remains important. Minimizing exposure to smoke from burning and wearing appropriate masks during dusty conditions are crucial preventative measures.
