Air pollution is an escalating concern for both environmental sustainability and public health, exacerbated by urbanization industrial growth. In Saudi Arabia, pollutants primarily from activities vehicle emissions present significant health hazards. This study utilizes data the Sentinel-5P satellite to analyze variations in Carbon Monoxide (CO), Nitrogen Dioxide (NO₂), Sulfur (SO₂), Particulate Matter (PM2.5) over a five-year period, January 2019 December 2023. The was processed using Google Earth Engine (GEE) produce monthly seasonal averages, while ArcGIS Pro used map trends spatial distribution. results reveal distinct fluctuations levels, with CO peaking between March-May July-September but showing overall decline. NO₂ SO₂ exhibit highs slight upward trends, likely linked output traffic emissions. PM2.5, most harmful pollutant human consistently surpasses World Health Organization (WHO) limits, especially during high-emission periods. These findings underscore urgency of adopting targeted measures mitigate critical times safeguard health. spikes, particularly densely populated regions, highlight need improved policies technologies effectively monitor manage air quality
