Considering the high spatial and temporal variations of water vapor, a timely and accurate retrieval of precipitable water vapor (PWV) is urgently needed, but has long been constrained by data availability. Our study derived the vertically integrated precipitable water vapor over eastern China using Multi-functional Transport Satellite (MTSAT) data, which is in geostationary orbit with high temporal resolution. The missing pixels caused by cloud contamination were reconstructed using an Empirical Orthogonal Function (EOF) decomposition method over both spatial and temporal dimensions. GPS meteorology data were used to validate the retrieval and the reconstructed results. The diurnal variation of PWV over eastern China was analyzed using harmonic analysis, which indicates that the reconstructed PWV data can depict the diurnal cycle of PWV caused by evapotranspiration and local thermal circulation.<\/jats:p>","DOI":"10.3390\/rs70505879","type":"journal-article","created":{"date-parts":[[2015,5,8]],"date-time":"2015-05-08T10:56:41Z","timestamp":1431082601000},"page":"5879-5900","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Geostationary Satellite Observation of Precipitable Water Vapor Using an Empirical Orthogonal Function (EOF) based Reconstruction Technique over Eastern China"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6439-6775","authenticated-orcid":false,"given":"Man","family":"Wong","sequence":"first","affiliation":[{"name":"Department of Land Surveying and Geo-Informatics, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong"}]},{"given":"Xiaomeng","family":"Jin","sequence":"additional","affiliation":[{"name":"Center for Sustainability and Global Environment, Nelson Institute for Environmental Studies, University of Wisconsin-Madison, Madison, WI 53726, USA"}]},{"given":"Zhizhao","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Land Surveying and Geo-Informatics, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong"}]},{"given":"Janet","family":"Nichol","sequence":"additional","affiliation":[{"name":"Department of Land Surveying and Geo-Informatics, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong"}]},{"given":"Shirong","family":"Ye","sequence":"additional","affiliation":[{"name":"GNSS Research Center, Wuhan University, 129 Luoyu Road, Wuhan 430079, China"}]},{"given":"Peng","family":"Jiang","sequence":"additional","affiliation":[{"name":"GNSS Research Center, Wuhan University, 129 Luoyu Road, Wuhan 430079, China"}]},{"given":"Pak","family":"Chan","sequence":"additional","affiliation":[{"name":"Hong Kong Observatory, Kowloon, Hong Kong"}]}],"member":"1968","published-online":{"date-parts":[[2015,5,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zveryaev, I.I., and Allan, R.P.
