Evaluating Air Pollution in Jakarta: A Dynamic Vehicle Age-Based Cohort Emission Models, Meteorological Effects, and COVID-19 Impacts ジャカルタの大気汚染の評価：動的車齢ベースコホート排出モデルと気象及びCOVID-19の影響 Merita Gidarjati open access air pollution|auto cohort model|emission inventory|transportation sector|air quality|COVID-19|meteorological variables. This study focuses on evaluating air pollution in Jakarta, emphasizing three main areas: the impact of motor vehicle emissions, the correlation between meteorological variables and air quality, and the effects of the COVID-19 pandemic on pollution levels.From 2007 to 2018, motorbikes emerged as the primary contributors to air pollutants. Projections indicate that by 2040, motorbikes will continue to dominate emissions, with expected contributions of 70.2% for CO, % for HC, and 82.9% for PM under a business-as-usual scenario. The research also found moderate correlations between temperature, humidity, rainfall, and PM levels during the COVID-19 pandemic, highlighting a complex interaction between environmental conditions and public health risks associated with air pollution. Even though there was a weak correlation between confirmed deaths because of COVID-19 and all air quality parameters, the study found positive cases of COVID-19 were strongly correlated with PM10, PM2.5, CO, and O3, whereas PM2.5 alone, showed a negative correlation. eng doctoral thesis VoR https://kitakyu.repo.nii.ac.jp/records/2000271 甲第285号 博士（工学） 2024-09-25 27101 北九州市立大学 https://kitakyu.repo.nii.ac.jp/record/2000271/files/(KKDE1285MG)甲第285号_メリタ ギダルジャティ.pdf application/pdf 2.5 MB 2024-12-25
