The product covers the period from 2003 to 2018, and the data represent a fusion of microwave radiometer observations, including those from the Special Sensor Microwave Imager Sounder (SSMIS), WindSat, Advanced Microwave Scanning Radiometer for Earth Observing System sensor (AMSR-E), Advanced Microwave Scanning Radiometer 2 (AMSR2), and HY-2A microwave radiometer (MR). The accuracy of this water vapor fusion product was validated using radiosonde water vapor observations. The comparative results show that the overall mean deviation (Bias) is smaller than 0.6 mm; the root mean square error (RMSE) and standard deviation (SD) are better than 3 mm, and the mean absolute deviation (MAD) and correlation coefficient (R) are better than 2 mm and 0.98, respectively.<\/jats:p>","DOI":"10.3390\/rs13122402","type":"journal-article","created":{"date-parts":[[2021,6,20]],"date-time":"2021-06-20T21:50:15Z","timestamp":1624225815000},"page":"2402","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["New Gridded Product for the Total Columnar Atmospheric Water Vapor over Ocean Surface Constructed from Microwave Radiometer Satellite Data"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5618-9477","authenticated-orcid":false,"given":"Weifu","family":"Sun","sequence":"first","affiliation":[{"name":"Marine Physics and Remote Sensing Research Department, First Institute of Oceanography, Ministry of Natural Resources, Qingdao 266061, China"},{"name":"Oceanic Telemetry Engineering and Technology Innovation Center, Qingdao 266061, China"}]},{"given":"Jin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Physics, Qingdao University, Qingdao 266071, China"}]},{"given":"Yuheng","family":"Li","sequence":"additional","affiliation":[{"name":"College of Geodesy and Geomatics, Shandong University of Science and Technology, Qingdao 266590, China"}]},{"given":"Junmin","family":"Meng","sequence":"additional","affiliation":[{"name":"Marine Physics and Remote Sensing Research Department, First Institute of Oceanography, Ministry of Natural Resources, Qingdao 266061, China"},{"name":"Oceanic Telemetry Engineering and Technology Innovation Center, Qingdao 266061, China"}]},{"given":"Yujia","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Marine and Information Space, China University of Petroleum (Huadong), Qingdao 266580, China"}]},{"given":"Peiqiang","family":"Wu","sequence":"additional","affiliation":[{"name":"Marine Physics and Remote Sensing Research Department, First Institute of Oceanography, Ministry of Natural Resources, Qingdao 266061, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2500","DOI":"10.1029\/2009RG000301","article-title":"Tropospheric water vapor, convection, and climate","volume":"48","author":"Sherwood","year":"2010","journal-title":"Rev.
