Assessment of air pollution at Greater Cairo in relation to the spatial variability of surface urban heat island.

Greater Cairo, Egypt, which lies in the apex of the Nile Delta, is one of the most populated regions in the world. Air pollution is a profound environmental issue prevailing in the urban/rural landscapes of this crowded megacity. The objectives of the present study were to utilize remotely sensed data in order to address the seasonal variations of the nocturnal surface urban heat island intensity (SUHII) as extracted from the American Moderate Resolution Imaging Spectroradiometer (MODIS) satellite and the related seasonal distribution of selected air pollutants, including nitrogen dioxide (NO), sulphur dioxide (SO), and carbon monoxide (CO) as extracted from the European TROPOspheric Monitoring Instrument (TROPOMI) for the period from 2018 to 2021.

Oceanographic factors of oil pollution dispersion offshore the Nile Delta (Egypt) using GIS.

Oil pollution is a worldwide concern due to the increasing rate of offshore oil production and transport. As the Nile Delta coast is adjacent to the main route of oil transport through the Suez Canal, accidental oil spills along the offshore region may have a tremendous impact on the coastal waters. If the oil slicks reach the coast, the impact should also be significant.
