Suruç is situated in the heart of the Upper Mesopotamian plain, within the Şanlıurfa province of southeastern Turkey. This strategically positioned town serves as a critical nexus between the Anatolian plateau and the vast Syrian desert. The terrain is characterized by expansive, flat alluvial plains, which facilitate intensive agricultural productivity but also leave the urban center vulnerable to wind-borne particulates. The absence of significant topographic barriers means that the city is frequently exposed to dust-laden air masses migrating north from the Arabian Peninsula and the Syrian Steppe. This geographic openness creates a distinct urban-rural gradient where the boundaries between residential zones and vast fields of cotton and pistachios are blurred. The proximity to the Euphrates basin influences the local microclimate, though the town lacks a major immediate waterfront to provide cooling evaporative effects. Consequently, the low elevation and flat landscape contribute to atmospheric stagnation during certain periods, trapping pollutants close to the ground. Industrial activity is minimal compared to agricultural output, yet the heavy reliance on machinery and the transport of goods across the regional corridor introduce localized combustion emissions. The interplay between the semi-arid soil and the open landscape ensures that mineral dust remains a primary component of the atmospheric composition, directly influencing the city's air quality profile and creating a challenging environment for respiratory health during periods of high wind activity across the Mesopotamian plains, making the region's air quality highly dependent on transboundary dust events.

The air quality narrative in Suruç is dictated by the stark contrast between the scorching dry summers and the mild, damp winters of the Mediterranean-influenced continental climate. During the summer months, the town experiences its most challenging periods as the "Khamsin" or similar hot, dry winds transport vast quantities of mineral dust from the south. These events lead to spikes in particulate matter, making outdoor activity hazardous for those with asthma or chronic obstructive pulmonary disease. As autumn arrives, the air typically clears, though the seasonal harvest often brings localized pollution from the burning of agricultural residues, which introduces organic aerosols into the lower atmosphere. Winter brings a transition to cooler temperatures and increased precipitation, which effectively scrubs the air of suspended particulates. However, this season is marked by temperature inversions, where cold air becomes trapped beneath a layer of warmer air, concentrating emissions from domestic heating systems, particularly those using coal or biomass. Spring is generally the most favorable time for outdoor pursuits, though it remains a transitional phase where sudden wind shifts can still trigger dust episodes. Sensitive groups, including children and the elderly, should limit prolonged outdoor exposure during the peak heat of July and August or during the stagnant, smoggy mornings of January. By monitoring wind directions and local weather alerts, residents can better navigate the seasonal fluctuations that define the atmospheric health of this historic Upper Mesopotamian settlement.
