Abstract

Over the past twenty years, the Middle East has experienced a surge in air pollution and dust, resulting in a range of issues affecting both people and the environment. Monitoring particulate matter (PM10 and PM2.5) has long been essential in assessing air quality. Thus, creating precise and proficient predictive models to estimate particulate matter concentrations is imperative for effectively managing and reducing air pollution. The estimation of seasonal and intra-annual PM concentrations was conducted in this study through the use of MLR and MLP models. A diverse range of meteorological parameters, including evaporation, temperature, wind speed, visibility, precipitation, and humidity, were employed along with aerosol optical depth (AOD). During autumn, the MLR and MLP models exhibited impressive performances. For PM10, the R values were 0.7 and 0.79, whereas for PM2.5, they were 0.7 and 0.81, respectively. The MLP’s superior correlation between the observed and estimated seasonal and intra-annual PM concentrations was noteworthy, as it consistently favored PM2.5 and highlighted the superiority of the ANN-MLP model over MLR. The predictive data underscored a correlation between PM concentration and the four seasons, emphasizing the seasonal impact on PM levels. Sensitivity analysis revealed that relative humidity (RH) was the primary factor influencing the intra-annual levels of both PM10 and PM2.5. This study offers valuable insights into comprehending the formation process, implementing effective control measures, and establishing predictive models for PM, all aimed at proficiently managing air quality.

分析预报 PM10 和 PM2.5 水平的气象因素:MLR 和 MLP 模型之间的比较
在过去的二十年里,中东地区的空气污染和灰尘激增,导致了一系列影响人类和环境的问题。长期以来,监测颗粒物(PM10 和 PM2.5)对评估空气质量至关重要。因此,建立精确、熟练的预测模型来估算颗粒物浓度,是有效管理和减少空气污染的当务之急。本研究通过使用 MLR 和 MLP 模型对季节性和年内的颗粒物浓度进行了估算。采用了多种气象参数,包括蒸发、温度、风速、能见度、降水和湿度,以及气溶胶光学深度(AOD)。在秋季,MLR 和 MLP 模型表现出令人印象深刻的性能。PM10 的 R 值分别为 0.7 和 0.79,而 PM2.5 的 R 值分别为 0.7 和 0.81。值得注意的是,MLP 在 PM2.5 的观测浓度与估计的季节浓度和年内浓度之间的相关性更强,因为它始终偏向于 PM2.5,突出了 ANN-MLP 模型优于 MLR 模型。预测数据强调了 PM 浓度与四季之间的相关性,突出了季节对 PM 浓度的影响。敏感性分析表明,相对湿度(RH)是影响 PM10 和 PM2.5 年内水平的主要因素。这项研究为理解可吸入颗粒物的形成过程、实施有效的控制措施和建立可吸入颗粒物的预测模型提供了宝贵的见解,所有这些都旨在有效地管理空气质量。

期刊介绍: The Earth Science Informatics [ESIN] journal aims at rapid publication of high-quality, current, cutting-edge, and provocative scientific work in the area of Earth Science Informatics as it relates to Earth systems science and space science. This includes articles on the application of formal and computational methods, computational Earth science, spatial and temporal analyses, and all aspects of computer applications to the acquisition, storage, processing, interchange, and visualization of data and information about the materials, properties, processes, features, and phenomena that occur at all scales and locations in the Earth system’s five components (atmosphere, hydrosphere, geosphere, biosphere, cryosphere) and in space (see "About this journal" for more detail). The quarterly journal publishes research, methodology, and software articles, as well as editorials, comments, and book and software reviews. Review articles of relevant findings, topics, and methodologies are also considered.
