Türkiye'deki Hava Kalitesi Dinamiklerinin Uydu Gözlemleri

Öz

Bu makalede, Türkiye'deki hava kirliliğinin on yıllık bir süre boyunca analizi sunulmaktadır. Çalışma, MERRA-2 uydu görüntülerinden elde edilen Kükürt dioksit (SO2), Sülfat (SO4), Organik Karbon Saçılması (OCS) ve Toplam Aerosol Angstrom parametre bileşenlerini analiz ederek atmosferdeki belirli kirleticilerin konsantrasyonlarını belirlemek için yürütülmüştür. SO2 ve SO4, atmosferdeki sülfat bileşenlerinin kütle yoğunluklarını temsil ederken, organik karbon atmosferik karbon saçılmasını temsil eder. Aerosol Angstrom parametresi, parçacık boyutu ve dağılımı hakkında önemli bilgiler sağlar. En orta düzeyde korelasyon, SO4 ve OCS arasında bulunmuştur (R değeri 0,63). Bu parametrelerin analiz edilmesi, Türkiye'deki hava kalitesi üzerindeki etkilerini ve değişimlerini anlamak için önemli bir adımdır. On yıllık Kara Yüzey Sıcaklığı (LST) verileri MODIS görüntülerinden elde edilmiştir. SO4, LST ile yüksek düzeyde korelasyona sahipken (R değeri: 0,85) OCS, LST ile orta düzeyde korelasyona sahiptir (R değeri 0,58). Bu çalışma, hava kirliliği profilini derinlemesine analiz etmeyi ve uzun vadeli verilerin analizine odaklanarak mevsimsel/uzun vadeli eğilimleri belirlemeyi amaçlamaktadır. Bu analiz, hava kalitesi yönetimi ve çevre politikası geliştirme için bilimsel temelli bir temel sağlamak adına önemli bir katkı sağlamaktadır.

Satellite Observations of Air Quality Dynamics in Türkiye

This paper presents an analysis of air pollution in Turkey over a ten-year period. The study was carried out to determine the concentrations of specific pollutants in the atmosphere by analyzing the Sulfur dioxide (SO2), Sulfate (SO4), Organic Carbon Scattering (OCS) and Total Aerosol Angstrom parameter components obtained from MERRA-2 satellite imagery. SO2 and SO4 represent the mass densities of sulphate components in the atmosphere, while organic carbon represents atmospheric carbon scattering. The aerosol Angstrom parameter provides important information on particle size and distribution. The most moderate correlation was found between SO4 and OCS (R value 0.63). Analyzing these parameters is an important step to understand their impacts and changes on air quality in Turkey. Ten years of Land Surface Temperature (LST) data were obtained from Modis images. SO4 was highly correlated with LST (R value: 0.85) and OCS was moderately correlated with LST (R value 0.58). This study aims to analyze the air pollution profile in depth and identify seasonal/long-term trends, focusing on the analysis of long-term data. This analysis provides an important contribution to provide a scientifically based basis for air quality management and environmental policy development.
