However, traditional pulsed lidar systems are relatively expensive and require considerable maintenance. These shortcomings may be overcome by the development of a blue band Scheimpflug lidar system in Dalian, Northern China. Atmospheric remote measurements were carried out for 10 days in an urban area to validate the feasibility and performance of a 450-nm Scheimpflug lidar system. A 24-h continuous measurement was achieved in winter on a near horizontal path with an elevation angle of about 6.4\u00b0. The aerosol extinction coefficient retrieved by the Fernald-inversion algorithm shows good agreement with the variation of PM10\/PM2.5 concentrations recorded by a national pollution monitoring station. The experimental result reveals that the linear ratio between the aerosol extinction coefficient and the PM10 concentration under high relative humidity (75\u201390%) is about two-times that in low relative humidity (\u226475%) when the PM10 concentrations are less than 100 \u00b5g\/m3.<\/jats:p>","DOI":"10.3390\/s18061880","type":"journal-article","created":{"date-parts":[[2018,6,8]],"date-time":"2018-06-08T11:19:31Z","timestamp":1528456771000},"page":"1880","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Atmospheric Pollution Monitoring in Urban Area by Employing a 450-nm Lidar System"],"prefix":"10.3390","volume":"18","author":[{"given":"Zheng","family":"Kong","sequence":"first","affiliation":[{"name":"School of Optoelectronic Engineering and Instrumentation Science, Dalian University of Technology, Dalian 116024, China"}]},{"given":"Zhi","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Engineering and Instrumentation Science, Dalian University of Technology, Dalian 116024, China"}]},{"given":"Lishan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Engineering and Instrumentation Science, Dalian University of Technology, Dalian 116024, China"}]},{"given":"Peng","family":"Guan","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Engineering and Instrumentation Science, Dalian University of Technology, Dalian 116024, China"}]},{"given":"Limei","family":"Li","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Engineering and Instrumentation Science, Dalian University of Technology, Dalian 116024, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1000-4497","authenticated-orcid":false,"given":"Liang","family":"Mei","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Engineering and Instrumentation Science, Dalian University of Technology, Dalian 116024, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3098","DOI":"10.1038\/ncomms4098","article-title":"Asian pollution climatically modulates mid-latitude cyclones following hierarchical modelling and observational analysis","volume":"5","author":"Wang","year":"2014","journal-title":"Nat.
