Kuppam, nestled in the Chittoor district of Andhra Pradesh, India, occupies a unique geographic position within the Deccan Plateau. Located at coordinates 12.7500°N, 78.3700°E, the town sits amidst undulating terrain, characterised by granite hills and shallow valleys. Its elevation, averaging around 830 meters, contributes to a relatively moderate climate compared to the coastal regions of Andhra Pradesh. The surrounding landscape is predominantly rural, dominated by agricultural lands – primarily dryland farming of crops like groundnut, millet, and pulses. Kuppam’s proximity to the Karnataka border influences its regional dynamics, acting as a crucial transit point. While not directly adjacent to major bodies of water, the town relies on local tanks and groundwater resources. The urban-rural gradient is sharply defined; Kuppam itself is a relatively small urban centre surrounded by a vast expanse of agricultural villages. Air quality is significantly impacted by this agrarian setting, with seasonal agricultural burning contributing to particulate matter. Dust from unpaved roads and construction activities, coupled with vehicular emissions from the increasing traffic flow, further degrade air quality. The lack of substantial industrial belts *within* Kuppam itself is a mitigating factor, but regional industrial activity can contribute to transboundary pollution.

Kuppam experiences a distinct seasonal air quality pattern dictated by the monsoon and prevailing winds. The pre-monsoon months of March to May are typically the worst for air quality. Rising temperatures create strong convective currents, dispersing pollutants less effectively, and agricultural practices like crop residue burning release significant amounts of particulate matter. The southwest monsoon, arriving in June and lasting until September, offers temporary relief. Rainfall washes away pollutants, and increased humidity suppresses dust. However, stagnant monsoon conditions can also lead to localised humidity-related issues. October and November see a gradual deterioration as the monsoon retreats, and cooler temperatures create temperature inversions, trapping pollutants near the ground. The winter months, December to February, are generally better than the pre-monsoon period, but still experience elevated pollution levels due to increased use of solid fuels for heating and calmer wind conditions. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during March-May and October-November. Monitoring wind direction is crucial; pollutants often drift from surrounding agricultural areas. Avoiding peak traffic hours can also reduce exposure.
