This study investigates the impact of socio-political disruptions on air quality in Khartoum, Sudan, focusing key pollutants: Aerosol Optical Depth (AOD), Carbon Monoxide (CO), Nitrogen Dioxide (NO₂), and Sulfur (SO₂). Using Sentinel-5P satellite data (2020–2024) processed Google Earth Engine (GEE), spatial temporal variations pollutant levels were analyzed before after a significant war event April 2023. The methodology included acquisition, preprocessing (e.g., cloud masking, filtering), monthly averages computation, visualization, statistical analysis using ArcGIS Pro, Microsoft Excel. Results showed marked post-war increase AOD levels, attributed to infrastructure destruction, fires, diminished industrial oversight, alongside spatially consistent pollution patterns some regions. CO concentrations exhibited an overall decline due reduced activities transportation, though localized anomalies linked concentrated emissions. Similarly, NO₂ dropped significantly, reflecting vehicular activities, while sporadic increases suggested emissions like generator use. SO₂ demonstrated mixed trends, with mean but increased variability, indicating high-emission events emergency fuel use or conflict-related disruptions. uniquely combines high-resolution advanced techniques reveal nuanced multi-pollutant conflicts providing novel insights into environmental repercussions armed conflicts. These findings highlight profound atmospheric dynamics, underscoring need for robust urban planning, targeted monitoring, policies mitigate deterioration address public health concerns conflict-prone emphasizes importance satellite-based monitoring provide critical upheavals.
