Shīshgarh, situated in Uttar Pradesh's Bareilly district at coordinates 28.7200°N, 79.3200°E, occupies a strategic position in the fertile Upper Gangetic Plain of northern India. This mid-sized urban center with over 750,000 residents lies approximately 250 kilometers east of Delhi, placing it within the broader Indo-Gangetic Plain's pollution corridor that stretches across South Asia. The city's terrain is predominantly flat, with an elevation around 170 meters above sea level, characteristic of the alluvial plains formed by the Ganges river system. Shīshgarh's location between the Ramganga River to the north and the Ganges to the south creates a hydrological context where seasonal water bodies influence local humidity patterns. The urban-rural gradient reveals a compact urban core surrounded by intensive agricultural zones, particularly sugarcane and wheat fields, where crop residue burning contributes significantly to regional pollution. Proximity to industrial clusters in Bareilly and Moradabad districts introduces additional particulate matter sources. The city's geography specifically affects air quality through its position in a topographical basin where pollutants accumulate due to limited ventilation, especially during winter months when temperature inversions trap emissions from urban activities, transportation, and agricultural practices. The surrounding landscape lacks significant topographic barriers to disperse pollution, making Shīshgarh vulnerable to both local emissions and transboundary haze from neighboring regions.

Shīshgarh experiences distinct seasonal air quality patterns shaped by the monsoon climate of northern India. During winter (December-February), pollution reaches its peak as cold temperatures create persistent ground-level inversions that trap particulate matter from urban sources, agricultural burning, and domestic heating. Dense fog frequently combines with pollutants to form toxic smog, making these months particularly hazardous for outdoor activity. Spring (March-May) brings gradual improvement as rising temperatures increase atmospheric mixing, though occasional dust storms from the Thar Desert can temporarily degrade air quality. The summer monsoon (June-September) offers the cleanest air as southwest winds bring vigorous rainfall that scrubs pollutants from the atmosphere, with July and August being optimal for outdoor exertion. Post-monsoon autumn (October-November) sees deteriorating conditions as agricultural fires resume and wind patterns shift, creating a buildup toward winter peaks. Sensitive groups including children, elderly residents, and those with respiratory conditions should minimize outdoor exposure during winter mornings when pollution concentrations are highest, use air purifiers indoors, and schedule essential activities for afternoon hours when slight atmospheric mixing occurs. Monitoring local air quality indices during transitional seasons is crucial, as sudden changes can occur with wind shifts or fire events.
