Özet
Aerosoller dogal süreçler ya da insan faaliyetleri sonucunda atmosfere karismakta ve iklim sartlarindan insan sagligina kadar birçok faktör üzerinde etkili olmaktadir. Bu çalismada 1 Ocak 2019 ve 19 Nisan 2021 tarihleri arasinda aerosol optik derinlik görüntüsü alinabilen toplam 292 günlük Moderate Resolution Imaging Spectroradiometer uncertainty ve 0.55 µm verileri kullanilmistir. Salginin etkisinin Türkiye’de ciddi anlamda hissedildigi 2020 Mart ayinin 15. günü analizlerde salgin öncesi ve salgin süreci ayrim günü olarak belirlenmistir. Türkiye’nin önemli sanayi kentleri arasinda yer alan Karabük ve Karadeniz Ereglisi arastirmanin alan kapsamini, bu sehirlerde Covid-19 salgin sürecinin aerosol optik derinligi üzerindeki etkisi ise konu kapsamini olusturmaktadir. Arastirmanin amaci salgin sürecinin aerosol optik derinligi üzerindeki etkisini ortaya koymaktir. Yapilan analizler sonucunda genel olarak uncertainty aerosol optik derinlik degerlerinde mevsimsel bir döngünün var oldugu tespit edilmistir. Uncertainty aerosol optik derinliginin hem genel ortalama hem de Covid 19 salgin süreci öncesi ve salgin sürecinde Karabük sehrinde Eregli’ye oranla daha fazla oldugu görülmektedir. Ayrica her iki çalisma alaninda da aerosol optik derinlik degerlerinde salgin sürecindeki 149 günlük dönemde, salgin öncesindeki 143 günlük döneme göre düsüs yasanmistir. 0.55 µm aerosol optik derinlik verileri ile yapilan analizlerde, uncertainty verilerine paralel olarak Covid 19 sürecinde azalma dikkat çekmekte ve azalma miktari artmaktadir. Karabük Kardemir 1 istasyonundan alinan partikül madde 10 degerleri ile analiz sonuçlari karsilastirildiginda mevsimsel döngü bakimindan benzerlik görülmekle birlikte en yüksek degerler sonbahar sonu ve kis baslarinda ortaya çikmaktadir. Ayrica salgin süreci ile birlikte partikül madde 10 miktarinda %32 gibi önemli oranda düsüs yasanmistir. Bu düsüste salgin süreciyle birlikte sanayi de dahil olmak üzere insan faaliyetlerinde meydana gelen yavaslamanin etkisi büyüktür.
Aerosols that influence many factors from climatic conditions to human health are mixed with the atmosphere because of natural processes or human activities. This study focuses on a total of 292 days of Moderate Resolution Imaging Spectroradiometer uncertainty and 0.55 µm data between January 1, 2019 and April 19, 2021 when aerosol optical depth images can be taken. March 15, 2020 was considered as the turning point for the pandemics which the effects started to be felt seriously in Turkey. The data was analyzed for two periods of time as before the Covid-19 pandemic and during the pandemic. The region of the study involves Karabük and Karadeniz Eregli where they are among the important industrial cities of Turkey while the scope involves the effect of the pandemic on aerosol optical depth. The purpose is to reveal the effect of pandemics on the aerosol optical depth. It has been determined that there is a seasonal cycle in the general uncertainty aerosol optical depth values. The Uncertainty aerosol optical depth is higher in Karabük than in Eregli on the general average both before the Covid 19 pandemics and during the pandemics. In addition, both locations had a decrease in aerosol optical depth values for the 149-day period during the pandemics compared to the 143-day period before the pandemics. The decrease in 0.55 µm aerosol optical depth and the uncertainty data during pandemics draw attention. Furthermore, the rate of reduction increases. When the particulate matter 10 values taken from Karabük Kardemir 1 station are compared with the analysis, there is a similarity in terms of the seasonal cycle, while the highest values occur in late autumn and early winter. With the pandemics, there was a significant decrease of 32% in the amount of particulate matter 10. The remarkable decrease is attributed to the great impact of the slowdown in human activities, including industries.
