Rāikot, a town nestled in the Ludhiana district of Punjab, India, occupies a geographically significant position within the Indo-Gangetic Plain. Located at approximately 30.65°N, 75.60°E, its terrain is predominantly flat, characteristic of the fertile alluvial plains formed by the Indus and Ganges river systems. The surrounding landscape is a mosaic of agricultural fields – primarily wheat and rice cultivation – interspersed with pockets of industrial activity, a common feature of Punjab’s urban-rural gradient. Rāikot’s proximity to Ludhiana, a major industrial hub, is a crucial factor influencing its air quality. The town sits within the broader Ludhiana Metropolitan Region, experiencing spillover effects from the larger city’s industrial emissions and vehicular traffic. While Rāikot itself is relatively small, its location within a densely populated and agriculturally intensive region creates a complex interplay of pollution sources. The elevation is low, around 240 meters above sea level, which can exacerbate the trapping of pollutants, particularly during periods of temperature inversion. There are no significant bodies of water immediately adjacent to Rāikot, limiting natural air purification processes. The urban-rural transition is gradual, with agricultural land gradually giving way to residential and light industrial areas within the town's boundaries. This blend of agricultural practices (including stubble burning) and industrial presence contributes to a unique air quality profile, demanding localized mitigation strategies.

Rāikot’s air quality follows a distinct seasonal pattern heavily influenced by regional weather systems and agricultural practices. The winter months (November to February) consistently present the most challenging conditions. Cold temperatures frequently lead to temperature inversions, where a layer of warm air traps cooler air near the ground, preventing pollutants from dispersing. Coupled with the prevalence of dense fog, a common occurrence during this period, this inversion effect significantly worsens air quality. Agricultural stubble burning, a widespread practice after the harvest of rice and wheat, adds a substantial load of particulate matter to the atmosphere. Spring (March-May) sees a gradual improvement as temperatures rise and winds increase, aiding in pollutant dispersion. However, dust storms originating from the Thar Desert can occasionally impact air quality. The monsoon season (June-September) brings relief, with rainfall washing away pollutants and increased wind speeds facilitating their removal. However, heavy rainfall can also lead to localized flooding and associated issues. The post-monsoon period (October) often sees a return to poorer air quality as agricultural activities ramp up again, preparing for the winter harvest and the subsequent burning. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the winter months, limiting outdoor exposure and using air purifiers when possible. During the peak burning season, wearing N95 masks is advisable for all residents.
