Impact of Built-up Areas Surrounding the International Baghdad Airport on Aviation Meteorology

This study focuses on the development of urbanization around International Baghdad Airport and its impact on aviation meteorology in terms of the vertical changes of air temperature and wind. Based on the results published in [Zeina, Al-Jiboori 2023], built-up areas were calculated using the satellite images of Landsat in ArcGIS 10.7 software in the month of July in five-year intervals between 1985 and 2020: 1985, 1990, 1995, 2000, 2005, 2010, 2015 and 2020. The result shows that surface air temperature has the lowest value, at 34.85 °C, in 1985, and the highest one, at 39.55 °C, in 2020. Variations in wind shear were also observed in 1990, 2005 and 2015 with a value of 0.06 s-1, while 2000 and 2020 both had a value of 0.054 s-1. In representing the relationship between the extracted areas and their meteorological parameters, we found a weak positive relationship between Built-up Index (BUI) area and air temperature, and a significant positive correlation between BUI areas and wind shear.
