Ageostrophic velocity induced by centrifugal force is not considered in altimeter products. This study introduces an iterative method to perform cyclogeostrophic corrections of mesoscale eddies\u2019 surface velocities derived from satellite altimeters. The corrected eddy velocity field and geostrophic velocity field were compared by combining eddy detection and mathematical statistics methods. The results show that eddies with small curvature radii, high roundness, or Rossby number larger than 0.1 illustrate that cyclogeostrophic correction is required. The cyclogeostrophic velocity is greater (less) than the geostrophic velocity in anticyclonic (cyclonic) eddies. Additionally, the iterative method is applied to cyclogeostrophic-corrected multi-year (1998\u20132012) Kuroshio surface velocities. The effect of cyclogeostrophic correction is significant for the Kuroshio Extension region, where the maximum relative difference of velocities with and without correction is about 10% and the eddy kinetic energy is 20%.<\/jats:p>","DOI":"10.3390\/rs15010184","type":"journal-article","created":{"date-parts":[[2022,12,30]],"date-time":"2022-12-30T03:18:18Z","timestamp":1672370298000},"page":"184","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Corrections of Mesoscale Eddies and Kuroshio Extension Surface Velocities Derived from Satellite Altimeters"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5341-6294","authenticated-orcid":false,"given":"Yuhan","family":"Cao","sequence":"first","affiliation":[{"name":"Jiangsu Key Laboratory of Marine Bioresources and Environment\/Jiangsu Key Laboratory of Marine Biotechnology, Jiangsu Ocean University, Lianyungang 222005, China"},{"name":"Co-Innovation Center of Jiangsu Marine Bio-Industry Technology, Jiangsu Ocean University, Lianyungang 222005, China"},{"name":"School of Marine Technology and Geomatics, Jiangsu Ocean University, Lianyungang 222005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changming","family":"Dong","sequence":"additional","affiliation":[{"name":"School of Marine Sciences, Nanjing University of Information Science and Technology, Nanjing 210044, China"},{"name":"Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai), Zhuhai 519082, China"},{"name":"Department of Atmosphere and Oceanic Sciences, University of California, Los Angeles, CA 90095, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zehao","family":"Qiu","sequence":"additional","affiliation":[{"name":"School of Marine Technology and Geomatics, Jiangsu Ocean University, Lianyungang 222005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5312-091X","authenticated-orcid":false,"given":"Brandon J.","family":"Bethel","sequence":"additional","affiliation":[{"name":"Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai), Zhuhai 519082, China"},{"name":"Small Island Sustainability, University of The Bahamas, Nassau 4912, Bahamas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiyun","family":"Shi","sequence":"additional","affiliation":[{"name":"Piesat Information Technology Co., Ltd., Beijing 100089, China"},{"name":"Beijing Presky Technology Co., Ltd., Beijing 100089, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8007-6619","authenticated-orcid":false,"given":"Haibin","family":"L\u00fc","sequence":"additional","affiliation":[{"name":"School of Marine Technology and Geomatics, Jiangsu Ocean University, Lianyungang 222005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yinhe","family":"Cheng","sequence":"additional","affiliation":[{"name":"School of Marine Technology and Geomatics, Jiangsu Ocean University, Lianyungang 222005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"94","DOI":"10.5670\/oceanog.2010.08","article-title":"Monitoring Ocean Currents with Satellite Sensors","volume":"23","author":"Dohan","year":"2010","journal-title":"Oceanography"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"L15606","DOI":"10.1029\/2007GL030812","article-title":"Global observations of large oceanic eddies","volume":"34","author":"Chelton","year":"2007","journal-title":"Geophys.
