We developed an automated compact mobile Raman lidar (MRL) system for\nmeasuring the vertical distribution of the water vapor mixing ratio (w) in\nthe lower troposphere, which has an affordable cost and is easy to operate.\nThe MRL was installed in a small trailer for easy deployment and can start\nmeasurement in a few hours, and it is capable of unattended operation for\nseveral months. We describe the MRL system and present validation results\nobtained by comparing the MRL-measured data with collocated radiosonde,\nGlobal Navigation Satellite System (GNSS), and high-resolution objective\nanalysis data. The comparison results showed that MRL-derived w agreed\nwithin 10 % (root-mean-square difference of\n1.05 g kg−1) with values obtained\nby radiosonde at altitude ranges between 0.14 and 1.5 km in the daytime and\nbetween 0.14 and 5–6 km at night in the absence of low clouds; the vertical\nresolution of the MRL measurements was 75–150 m, their temporal resolution\nwas less than 20 min, and the measurement uncertainty was less than 30 %.\nMRL-derived precipitable water vapor values were similar to or slightly lower\nthan those obtained by GNSS at night, when the maximum height of MRL\nmeasurements exceeded 5 km. The MRL-derived w values were at most 1 g kg−1\n(25 %) larger than local analysis data. A total of 4 months of continuous operation\nof the MRL system demonstrated its utility for monitoring water vapor\ndistributions in the lower troposphere.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004240187516544","@type":"Researcher","foaf:name":[{"@value":"Tetsu Sakai"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004240187516547","@type":"Researcher","foaf:name":[{"@value":"Tomohiro Nagai"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004240187516545","@type":"Researcher","foaf:name":[{"@value":"Toshiharu Izumi"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004240187516546","@type":"Researcher","foaf:name":[{"@value":"Satoru Yoshida"}]},{"@id":"https://cir.nii.ac.jp/crid/1030003658641296258","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"70354446"},{"@type":"NRID","@value":"1000070354446"},{"@type":"NRID","@value":"9000396184062"},{"@type":"NRID","@value":"9000396184223"},{"@type":"NRID","@value":"9000396184142"},{"@type":"NRID","@value":"9000396184329"},{"@type":"NRID","@value":"9000368424791"},{"@type":"NRID","@value":"9000257768109"},{"@type":"NRID","@value":"9000363404555"},{"@type":"NRID","@value":"9000363404725"},{"@type":"NRID","@value":"9000363404630"}],"foaf:name":[{"@value":"Yoshinori Shoji"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"18678548"}],"prism:publicationName":[{"@value":"Atmospheric Measurement Techniques"}],"dc:publisher":[{"@value":"Copernicus GmbH"}],"prism:publicationDate":"2019-01-17","prism:volume":"12","prism:number":"1","prism:startingPage":"313","prism:endingPage":"326"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["https://creativecommons.org/licenses/by/4.0/"],"url":[{"@id":"https://amt.copernicus.org/articles/12/313/2019/amt-12-313-2019.pdf"}],"createdAt":"2019-01-17","modifiedAt":"2025-02-01","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Earthwork.%20Foundations","dc:title":"Earthwork.
