Moka, a small town in the Davanagere district of Karnataka, India, sits at coordinates 15.2380°N, 77.0599°E. The terrain is largely characterised by the Deccan Plateau, a relatively flat, elevated region with gentle undulations. Moka’s elevation, approximately 620 meters above sea level, influences local weather patterns and pollutant dispersion. The surrounding landscape is predominantly agricultural, with significant areas dedicated to paddy cultivation and other seasonal crops. This agricultural activity, while vital to the local economy, contributes to particulate matter pollution through practices like crop residue burning. The town is not directly adjacent to any major bodies of water, though smaller streams and tanks are present, influencing localised humidity. While Moka itself isn’t a major industrial hub, its proximity to Davanagere, a growing industrial centre, means it experiences some degree of regional industrial fallout. The urban-rural gradient is quite sharp; Moka retains a distinctly rural character, but is increasingly influenced by the economic and infrastructural developments occurring in nearby cities. This transition impacts air quality as increased vehicular traffic and construction activity become more prevalent. The prevailing winds, influenced by the monsoon systems, play a crucial role in pollutant transport and dispersion, often carrying pollutants from surrounding areas into and through Moka.

Moka experiences a tropical climate with distinct wet and dry seasons. Air quality generally worsens during the dry season (October to May), peaking in March and April. This is due to lower rainfall, reduced wind speeds, and increased dust from agricultural activities and unpaved roads. Temperature inversions, common during cooler mornings in the dry season, trap pollutants near the ground, exacerbating the problem. The monsoon season (June to September) brings significant relief, with heavy rainfall effectively washing away pollutants and increasing humidity, which suppresses dust. However, increased cloud cover can also lead to stagnant air conditions. October sees a transitional period with fluctuating air quality. For sensitive groups – children, the elderly, and those with respiratory conditions – avoiding outdoor activity during the peak dry season months is advisable. During the monsoon, while air is cleaner, the increased humidity can trigger respiratory issues in some. Fog, common in the cooler months, can also trap pollutants. Monitoring local weather patterns and being mindful of personal health conditions are crucial for managing exposure. The post-monsoon period can see a temporary increase in pollutants as dust settles and agricultural burning resumes.
