On the one hand, the dust invasion brings many primary aerosols and causes a large range of transboundary transport. On the other hand, the high concentration of aerosol causes a severe disturbance to the distribution of O3. Traditionally, high-resolution assessments of the spatial distribution of aerosols and O3 can be carried out using LiDAR technology. However, the negligence of the influence of aerosols in the process of O3 retrieval in traditional differential absorption lidar (DIAL) leads to an error in the accuracy of ozone concentration. Especially when dust transit occurs, the errors become bigger. In this study, a self-customized four-wavelength differential-absorption LiDAR system was used to synchronously obtain the accurate vertical distributions of ozone and high-concentration aerosol. The wavelength index of concentrated aerosol was inverted and applied to the differential equation framework for O3 calculation. This novel approach to retrieving the vertical profile of O3 was proposed and verified by applying it to a dust pollution event that occurred from April to May 2021 in Anyang City Henan Province, which is located in Northern China. It was found that the extinction coefficient of aerosol reached 2.5 km\u22121 during the dust period, and O3 was mainly distributed between 500 m and 1500 m. The O3 error exceeded over 10% arising from the high-concentration aerosol below 1.5 km during the dust storm event. By employing the inversion algorithm while considering the aerosol effects, the ozone concentration error was improved by over 10% compared with the error recorded without considering the aerosol influence especially in dust events. Through this study, it was found that the algorithm could effectively realize the synchronous and accurate inversion of high-concentration aerosols and O3 and can provide key technical support for air pollution control in China in the future.<\/jats:p>","DOI":"10.3390\/rs16162997","type":"journal-article","created":{"date-parts":[[2024,8,15]],"date-time":"2024-08-15T09:29:41Z","timestamp":1723714181000},"page":"2997","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Accurate Inversion of the Vertical Ozone Profile in High-Concentration Aerosols Based on a New DIAL-A Case Study"],"prefix":"10.3390","volume":"16","author":[{"given":"Na","family":"Ma","sequence":"first","affiliation":[{"name":"Institute of Environment, Hefei Comprehensive National Science Center, Hefei 230031, China"}]},{"given":"Jie","family":"Wang","sequence":"additional","affiliation":[{"name":"Institutes of Physical Science and Information Technology, Anhui University, Hefei 230601, China"},{"name":"Information Materials and Intelligent Sensing Laboratory of Anhui Province, Anhui University, Hefei 230601, China"}]},{"given":"Chenglei","family":"Pei","sequence":"additional","affiliation":[{"name":"Guangzhou Sub-branch of Guangdong Ecological and Environmental Monitoring Center, Guangzhou 510006, China"}]},{"given":"Sipeng","family":"Yang","sequence":"additional","affiliation":[{"name":"Guangzhou Institute of Tropical and Marine Meteorology, China Meteorological Administration, Guangzhou 510180, China"}]},{"given":"Tianshu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Environment, Hefei Comprehensive National Science Center, Hefei 230031, China"},{"name":"Key Laboratory of Environmental Optics and Technology, Anhui Institutes of Optics and Fine Mechanics, Chinese Academy of Sciences, Hefei 230031, China"}]},{"given":"Yujun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Environment, Hefei Comprehensive National Science Center, Hefei 230031, China"}]},{"given":"Jianing","family":"Wan","sequence":"additional","affiliation":[{"name":"Wuxi Cas Photonics Co., Ltd., Wuxi 214028, China"}]},{"given":"Yiwei","family":"Xu","sequence":"additional","affiliation":[{"name":"Institutes of Physical Science and Information Technology, Anhui University, Hefei 230601, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,15]]},"reference":[{"key":"ref_1","first-page":"2481","article-title":"Spatial and temporal distribution characteristics of ozone in Urban agglomerations in China","volume":"42","author":"Lin","year":"2022","journal-title":"China Environ.
