Gidri, a town nestled in the fertile plains of Punjab, India, occupies a geographically significant position within the broader Indo-Gangetic Plain. Located at approximately 30.8461° N, 75.8623° E, its coordinates place it squarely within a region characterized by flat, alluvial terrain formed over millennia by the Indus and its tributaries. The surrounding landscape is predominantly agricultural, a patchwork of cultivated fields supporting Punjab’s renowned agricultural output, particularly wheat and rice. This intensive farming contributes to seasonal agricultural burning, a significant factor in regional air quality. Gidri’s elevation is relatively low, around 228 meters above sea level, which, combined with the flat topography, limits atmospheric dispersion of pollutants. The town sits within a gradual urban–rural gradient, transitioning from the denser urban areas of Ludhiana, approximately 40 kilometers to the east, to the more sparsely populated rural hinterland. While Gidri itself is a smaller urban center, its proximity to industrial belts around Ludhiana and Jalandhar introduces a secondary source of pollution. The lack of significant natural barriers, such as hills or large bodies of water, further exacerbates the issue, allowing pollutants to accumulate. The climate is subtropical, with hot summers and cool winters, influencing atmospheric stability and impacting the behaviour of airborne particles. The region's vulnerability to dust storms originating from the Thar Desert, though less frequent than in Rajasthan, also contributes to particulate matter levels.

Gidri’s air quality follows a distinct seasonal pattern dictated by meteorological conditions and agricultural practices. The winter months (November to February) are typically the most challenging. Cold temperatures frequently lead to temperature inversions, trapping pollutants close to the ground and resulting in stagnant air. Dense fog, a common occurrence during this period, further restricts dispersion. Agricultural burning, a widespread practice to clear crop residue after the harvest of rice and wheat, peaks during this time, releasing substantial amounts of particulate matter and gases. Spring (March-May) sees a gradual improvement as temperatures rise and winds increase, aiding in pollutant dispersal. However, dust storms can still impact air quality. The monsoon season (June-September) brings relief, with rainfall washing away pollutants and increased wind speeds facilitating ventilation. However, heavy rainfall can also lead to localised flooding and associated issues. The post-monsoon period (October) often sees a brief return to poorer air quality as agricultural burning begins again, albeit at a lower intensity than in winter. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the winter months, limiting outdoor activity during peak pollution episodes. During the winter, indoor air quality is also a concern, and ventilation should be carefully managed. The spring months offer a better window for outdoor activities, but vigilance regarding dust levels is advisable. The monsoon provides a respite, but awareness of potential flooding impacts is crucial. Overall, minimizing exposure to smoke and dust, and maintaining good respiratory health, are essential throughout the year.
