Şarkışla, nestled in the Sivas Province of Turkey at coordinates 39.3500, 36.4000, occupies a significant position within the Central Anatolia region. The city’s elevation, averaging around 1,280 meters (4,200 feet), contributes to a continental climate characterized by hot, dry summers and cold, snowy winters. Şarkışla is situated within a broad plateau landscape, punctuated by rolling hills and the Kızılırmak River, Turkey’s longest river, flowing nearby. This river valley, while providing some moisture, doesn’t significantly mitigate the overall aridity. The surrounding terrain is predominantly agricultural, with wheat and barley fields dominating the landscape, alongside livestock farming. While Şarkışla isn’t a major industrial hub, smaller-scale industries related to agriculture and food processing are present. The urban-rural gradient is quite sharp; the city centre quickly transitions into open farmland. This geographical setting directly impacts air quality. The plateau’s topography can trap pollutants during temperature inversions, particularly in winter when heating demands increase. Dust from agricultural activities and soil erosion also contributes to particulate matter, especially during drier periods. The distance from major coastal influences limits the flushing effect of sea breezes, exacerbating pollutant concentration. The prevailing winds, generally from the west, can transport pollutants from other regions, adding to local emissions.

Şarkışla’s air quality follows a distinct seasonal pattern. Winter (December-February) typically sees the poorest air quality, driven by increased coal and wood burning for heating, coupled with frequent temperature inversions that trap pollutants close to the ground. Calm, cold conditions prevent dispersion, leading to elevated particulate matter concentrations. Spring (March-May) brings some improvement as temperatures rise and heating needs decrease, but dust storms from surrounding agricultural lands can still impact air quality. Summer (June-August) generally offers the cleanest air, with higher temperatures, stronger winds, and less reliance on combustion for heating. However, prolonged drought conditions can exacerbate dust pollution. Autumn (September-November) is a transitional period. As temperatures cool and heating begins, pollutant levels gradually increase. October often experiences a spike in particulate matter due to agricultural burning after the harvest. Sensitive groups – children, the elderly, and those with respiratory conditions – should be particularly cautious during winter and autumn. Avoiding strenuous outdoor activity on cold, still days is advisable. Monitoring local conditions and staying indoors when pollution is high is crucial. The dry climate necessitates staying hydrated to mitigate respiratory irritation. Months of June, July and August are generally the most favourable for outdoor activities.
