Jagannāthaprasād, nestled in the coastal Odisha region of eastern India, occupies a geographically significant position within the Ganjam district. Located at approximately 19.97°N, 84.77°E, the city’s terrain is predominantly undulating, transitioning from gently sloping plains towards the east to slightly more elevated ground inland. This topography influences local wind patterns and can contribute to localized air quality variations. The city sits relatively close to the Bay of Bengal, approximately 30 kilometers away, impacting humidity levels and occasionally introducing saline aerosols into the atmosphere, particularly during storm events. Surrounding Jagannāthaprasād is a mosaic of agricultural land, primarily dedicated to rice cultivation and pulses, interspersed with pockets of cashew plantations – a characteristic feature of the Odisha landscape. To the west, the terrain gradually rises, hinting at the foothills of the Eastern Ghats, though the city itself doesn't directly abut these ranges. The urban–rural gradient is relatively smooth; the city blends seamlessly into the surrounding agricultural areas, with smaller villages and rural settlements visible within a short distance. Industrial activity is limited within Jagannāthaprasād itself, but the broader Ganjam district hosts some light industries and processing units, potentially contributing to regional air pollution transported by prevailing winds. The coastal location also means the city is susceptible to dust storms originating from the Bay of Bengal and the inland arid regions, further complicating the air quality profile. The elevation, averaging around 30 meters above sea level, contributes to a generally warm and humid climate, impacting pollutant dispersion.

Jagannāthaprasād experiences a distinct tropical climate, characterized by a wet and dry season, significantly influencing its air quality. The dry season, typically spanning from March to May, often witnesses a noticeable increase in particulate matter. This is largely attributed to increased agricultural burning as farmers clear fields for the monsoon planting season, combined with lower rainfall to wash pollutants from the atmosphere. Dust storms, frequently originating from the northwest, are also more prevalent during this period, exacerbating the issue. Temperature inversions, common during calmer nights, can trap pollutants close to the ground, leading to localized spikes. The monsoon season, from June to September, brings relief as heavy rainfall effectively cleanses the air, significantly reducing particulate concentrations. However, the monsoon also introduces humidity, which can affect the respiratory system. October and November represent a transitional period, with gradually decreasing rainfall and a potential for increased dust as the monsoon recedes. December and January are generally cooler and drier, with occasional fog, which can trap pollutants and reduce visibility. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly during agricultural burning periods. Outdoor activities are generally more favorable during the monsoon months, although humidity should be considered. The interplay of wind patterns, temperature fluctuations, and agricultural practices dictates the seasonal air quality narrative in Jagannāthaprasād, demanding adaptive strategies for public health.
