Gundlupēt, nestled in the Chamarajanagar district of Karnataka, India, occupies a geographically significant position within the Deccan Plateau. Located at approximately 11.8°N latitude and 76.68°E longitude, the town sits at an elevation of roughly 930 meters (3,051 feet) above sea level, contributing to a relatively cool and pleasant climate compared to lower-lying regions of Karnataka. The surrounding landscape is characterized by undulating hills, scrub forests, and agricultural fields, reflecting the transition zone between the drier plains and the Western Ghats. Gundlupēt’s proximity to the Cauvery Wildlife Sanctuary influences its air quality, with potential for biomass burning during agricultural cycles. The town’s urban character is primarily that of a market town and agricultural hub, with a moderate population density. The urban–rural gradient is relatively sharp, with agricultural lands dominating the immediate periphery. While not directly adjacent to major rivers, the region receives significant rainfall during the monsoon season, impacting atmospheric moisture and pollutant dispersion. The absence of large-scale heavy industries within Gundlupēt itself mitigates some pollution risks, however, agricultural practices, including the burning of crop residue, and vehicular emissions from increasing traffic contribute to localized air quality concerns. The plateau's topography can sometimes trap pollutants, particularly during periods of low wind speed, influencing the overall air quality profile. The regional position, far from major metropolitan areas, generally results in lower baseline pollution levels compared to larger Indian cities.

Gundlupēt’s air quality exhibits a distinct seasonal pattern dictated by the region’s tropical climate and monsoon influence. The dry season, typically spanning from March to May, often witnesses a gradual increase in particulate matter due to increased dust from agricultural activities and road construction. Temperature inversions, common during these months, can trap pollutants near the ground, exacerbating localized air quality issues. The monsoon season, from June to September, brings relief with frequent rainfall, effectively washing away pollutants and significantly improving air quality. However, the onset of the monsoon can initially be accompanied by increased humidity and occasional dust storms. The post-monsoon season (October-November) sees a return to drier conditions, with agricultural burning becoming a significant contributor to particulate pollution. The winter months (December-February) are generally characterized by cooler temperatures and calmer winds, which can lead to stagnant air and a potential build-up of pollutants, particularly during periods of fog. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season and post-monsoon period, limiting prolonged outdoor exposure and avoiding strenuous activities. The monsoon months offer the most favourable conditions for outdoor activities, while the winter months require vigilance regarding potential air quality degradation. Agricultural practices and seasonal wind patterns are the dominant drivers of air quality fluctuations in Gundlupēt, making awareness of these trends crucial for public health.
