Chittaurgarh, a historic city in Rajasthan, India, occupies a strategically significant location within the Mewar region. Situated at approximately 24.88°N, 74.63°E and an elevation of roughly 271 meters (889 feet) above sea level, the city’s geography is dominated by the imposing Chittaur Fort, a UNESCO World Heritage site, which dramatically shapes the urban landscape. The terrain surrounding Chittaurgarh is predominantly semi-arid, characterized by undulating plains and rocky outcrops, typical of the Thar Desert's fringes. While not directly adjacent to a major river, the city benefits from the proximity of the Gambhiri River, which flows nearby, influencing local microclimates and providing some moisture. The urban fabric of Chittaurgarh blends historical architecture with modern development, creating a unique visual character. The city’s regional position places it within a transitional zone between the arid desert and the more fertile plains of Rajasthan. Surrounding Chittaurgarh are primarily agricultural lands, supporting crops like wheat, maize, and pulses, alongside livestock grazing. This agricultural activity, coupled with occasional burning of crop residue, contributes to localized air pollution. Further afield, industrial belts in larger Rajasthani cities like Udaipur and Bhilwara exert a regional influence on air quality, with pollutants potentially transported by prevailing winds. The urban-rural gradient around Chittaurgarh is relatively gradual, with smaller villages and agricultural settlements seamlessly blending into the city's periphery, impacting the dispersion of pollutants and creating a complex interplay between urban and rural air quality dynamics.

Chittaurgarh’s air quality experiences a distinct seasonal cycle dictated by the region’s climate. The hot, dry summer months (March to May) are often characterized by stagnant air and elevated particulate matter concentrations. High temperatures suppress convective mixing, leading to temperature inversions that trap pollutants near the ground. Dust storms, common during this period, significantly worsen air quality, carrying fine particles over long distances. The monsoon season (June to September) brings relief, with increased rainfall and wind speeds dispersing pollutants. However, monsoon onset can initially be accompanied by increased humidity and localized flooding, which can temporarily affect air quality. The post-monsoon season (October to November) sees a return to drier conditions, with a gradual increase in pollution levels as agricultural activities resume. Burning of crop residue, a common practice in surrounding rural areas, contributes significantly to particulate pollution during this time. Winter months (December to February) are typically the most challenging, with cold temperatures and frequent fog episodes. Fog traps pollutants, reducing visibility and exacerbating respiratory issues. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should limit outdoor exposure during these periods, particularly during the winter months and the dry summer season. Maintaining indoor air quality through ventilation and air purifiers is also advisable. The city’s location, nestled within a semi-arid landscape, means that wind patterns are often variable, making accurate predictions of pollutant dispersion difficult.
