Air pollution has become a critical issue in urban areas, so a broad understanding of its spatiotemporal characteristics is important to develop public policies. This study analyzes the spatiotemporal variation of atmospheric particulate matter (PM₁₀ and PM_2.5) and ozone (O₃) in Barranquilla, Colombia from March 2018 to June 2019 in three monitoring stations. The average concentrations observed for the Móvil, Policía, and Tres Avemarías stations, respectively, for PM₁₀: 46.4, 51.4, and 39.7 μg/m³; for PM_2.5: 16.1, 18.1, and 15.1 μg/m³ and for O₃: 35.0, 26.6, and 33.6 μg/m³. The results indicated spatial and temporal variations between the stations and the pollutants evaluated. The highest PM concentrations were observed in the southern part of the city, while for ozone, higher concentrations were observed in the north. These variations are mainly associated with the influence of local sources in the environment of each site evaluated as well as the meteorological conditions and transport patterns of the study area. This study also verified the existence of differences in the concentrations of the studied pollutants between the dry and rainy seasons and the contribution of local sources as biomass burnings from the Isla Salamanca Natural Park and long-range transport of dust particles from the Sahara Desert. This study provides a scientific baseline for understanding air quality in the city, which enables policy makers to adopt efficient measures that jointly prevent and control pollution.

空气污染已成为城市地区的一个关键问题，因此对其时空特征的广泛了解对于制定公共政策非常重要。本研究分析了哥伦比亚巴兰基亚 2018 年 3 月至 2019 年 6 月三个监测站大气颗粒物（PM ₁₀和 PM _2.5）和臭氧（O ₃）的时空变化。在 Móvil、Policía 和 Tres Avemarías 站观察到的 PM ₁₀的平均浓度分别为：46.4、51.4和 39.7 μg/m ³；PM _2.5：16.1、18.1 和 15.1 μg/m ³以及 O ₃：35.0、26.6 和 33.6 μg/m ³. 结果表明站点和评估的污染物之间的空间和时间变化。在城市南部观察到的 PM 浓度最高，而对于臭氧，在北部观察到更高的浓度。这些变化主要与评估的每个站点的环境中本地源的影响以及研究区域的气象条件和运输模式有关。这项研究还验证了旱季和雨季之间研究的污染物浓度存在差异，以及当地来源的贡献，如来自萨拉曼卡岛自然公园的生物质燃烧和来自撒哈拉沙漠的灰尘颗粒的远程传输。本研究为了解城市空气质量提供了科学基准，
