The approach of synchronous 3-D detection of wind and pollution using a solo coherent Doppler wind lidar (CDWL) is developed and demonstrated. The 3-D distribution of pollutant is depicted by the backscatter coefficient based on signal intensity of CDWL. Then, a high-resolution wind field is derived to track the local air pollution source with its diffusion and to analyze transboundary air pollution episodes. The approach is experimentally implemented in a chemical industry park. Smoke plumes caused by point source pollutions are captured well using plan position indicator (PPI) scanning with low elevation. A typical source of pollution is located, combining the trajectory of the smoke plume and the horizontal wind vector. In addition, transboundary air pollution caused by the transport of dust storms is detected in a vertical profile scanning pattern, which is consistent with the results of national monitoring stations and backward trajectory models. Our present work provides a significant 3-D detection approach to air pollution monitoring with its sources, paths, and heights by using a solo-CDWL system.<\/jats:p>","DOI":"10.3390\/rs14122809","type":"journal-article","created":{"date-parts":[[2022,6,12]],"date-time":"2022-06-12T23:55:24Z","timestamp":1655078124000},"page":"2809","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Real-Time Synchronous 3-D Detection of Air Pollution and Wind Using a Solo Coherent Doppler Wind Lidar"],"prefix":"10.3390","volume":"14","author":[{"given":"Jinlong","family":"Yuan","sequence":"first","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science and Technology, Nanjing 210044, China"},{"name":"School of Earth and Space Science, University of Science and Technology of China, Hefei 230026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunbin","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Earth and Space Science, University of Science and Technology of China, Hefei 230026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhifeng","family":"Shu","sequence":"additional","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science and Technology, Nanjing 210044, China"},{"name":"Nanjing Taixin Co., Ltd., Nanjing 211899, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lian","family":"Su","sequence":"additional","affiliation":[{"name":"School of Earth and Space Science, University of Science and Technology of China, Hefei 230026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dawei","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Earth and Space Science, University of Science and Technology of China, Hefei 230026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3486-6286","authenticated-orcid":false,"given":"Yuanjian","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science and Technology, Nanjing 210044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingjing","family":"Dong","sequence":"additional","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science and Technology, Nanjing 210044, China"},{"name":"Nanjing Taixin Co., Ltd., Nanjing 211899, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saifen","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science and Technology, Nanjing 210044, China"},{"name":"Nanjing Taixin Co., Ltd., Nanjing 211899, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhen","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science and Technology, Nanjing 210044, China"},{"name":"Nanjing Taixin Co., Ltd., Nanjing 211899, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiyun","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science and Technology, Nanjing 210044, China"},{"name":"School of Earth and Space Science, University of Science and Technology of China, Hefei 230026, China"},{"name":"Nanjing Taixin Co., Ltd., Nanjing 211899, China"},{"name":"National Laboratory for Physical Sciences at the Microscale, University of Science and Technology of China, Hefei 230026, China"},{"name":"Institute of Software, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2239","DOI":"10.4209\/aaqr.2018.12.0471","article-title":"Current Status of Fine Particulate Matter (PM2.5) in Vietnam\u2019s Most Populous City, Ho Chi Minh City","volume":"19","author":"Hien","year":"2019","journal-title":"Aerosol Air Qual.
