Chotāla, nestled in Haryana, India (29.7808° N, 74.5226° E), occupies a geographically significant position within the Indo-Gangetic Plain. The town’s terrain is predominantly flat, characteristic of the alluvial plains formed by the Indus and Ganges river systems, resulting in minimal elevation changes. This flatness, while agriculturally advantageous, contributes to air quality challenges. Chotāla lies within a region heavily reliant on agriculture, particularly wheat and rice cultivation, which introduces seasonal biomass burning as a significant pollution source. Surrounding the town is a mosaic of agricultural fields interspersed with smaller villages, creating a gradual urban-rural gradient. The proximity to industrial belts in nearby cities like Bhiwani and Jind, though not immediately adjacent, influences regional air pollution patterns, with pollutants transported by prevailing winds. The absence of major water bodies within immediate proximity limits natural air purification processes; the nearest substantial riverine influence is further east. The flat topography and lack of significant wind channeling exacerbate the accumulation of pollutants, especially during periods of atmospheric stability. The region's climate, characterized by hot summers and cool winters, further impacts air quality, with temperature inversions frequently trapping pollutants close to the ground. The surrounding landscape, largely agricultural, dictates the dominant sources of particulate matter, making Chotāla’s air quality intrinsically linked to regional farming practices and industrial activity.

Chotāla’s air quality follows a distinct seasonal cycle heavily influenced by meteorological conditions and agricultural practices. The dry winter months (November to February) typically experience the poorest air quality. Cold temperatures promote temperature inversions, where a layer of warm air sits above cooler air near the ground, preventing vertical mixing and trapping pollutants. Frequent fog, common during this period, further reduces visibility and concentrates particulate matter. Stubble burning after the harvest of rice and wheat crops is a major contributor to elevated pollution levels during these months, releasing significant amounts of smoke and particulate matter. Spring (March-May) sees a gradual improvement as temperatures rise, and wind speeds increase, dispersing pollutants. 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 aiding dispersion. However, heavy rainfall can also lead to waterlogging and the release of methane from agricultural lands. The post-monsoon period (October) often sees a brief return to poorer air quality as conditions become drier and calmer before the onset of winter. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the winter months, limiting outdoor activity and wearing masks when necessary. During the peak agricultural burning season (November-December), even healthy individuals should minimize prolonged exposure to outdoor air.
