Using 256 buoy measurements collocated with RADARSAT-2 fine beam quad-polarized scenes, RCM CP data was simulated using a \u201cCP simulator\u201d. Provided that the relative wind direction is known, our results demonstrate that wind speed can be retrieved from RV, RH and RL polarization channels using existing C-band model (CMOD) geophysical model function (GMF) and polarization ratio (PR) models. Simulated RR-polarized radar returns have a strong linear relationship with speed and are less sensitive to relative wind direction and incidence angle. Therefore, a model is proposed for the RR-polarized synthetic aperture radar (SAR) data. Our results show that the proposed model can provide an efficient methodology for wind speed retrieval.<\/jats:p>","DOI":"10.3390\/rs11161876","type":"journal-article","created":{"date-parts":[[2019,8,12]],"date-time":"2019-08-12T06:38:02Z","timestamp":1565591882000},"page":"1876","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Ocean Surface Wind Speed Retrieval Using Simulated RADARSAT Constellation Mission Compact Polarimetry SAR Data"],"prefix":"10.3390","volume":"11","author":[{"given":"He","family":"Fang","sequence":"first","affiliation":[{"name":"Zhejiang Climate Centre, Hangzhou 310017, China"}]},{"given":"William","family":"Perrie","sequence":"additional","affiliation":[{"name":"Fisheries &amp; Oceans Canada, Bedford Institute of Oceanography, Dartmouth, NS B2Y 4A2, Canada"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4984-3925","authenticated-orcid":false,"given":"Guosheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Marine Sciences, Nanjing University of Information Science and Technology, Nanjing 210044, China"}]},{"given":"Tao","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Remote Sensing and Geomatics Engineering, Nanjing University of Information Science and Technology, Nanjing 210044, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2046-7690","authenticated-orcid":false,"given":"Shahid","family":"Khurshid","sequence":"additional","affiliation":[{"name":"Earth Applied Science &amp; Development Section Observation &amp; Geomatics, Meteorological Service of Canada, Environment and Climate Change Canada, Ottawa, ON K1A 0H3, Canada"}]},{"given":"Kerri","family":"Warner","sequence":"additional","affiliation":[{"name":"Earth Applied Science &amp; Development Section Observation &amp; Geomatics, Meteorological Service of Canada, Environment and Climate Change Canada, Ottawa, ON K1A 0H3, Canada"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7514-3212","authenticated-orcid":false,"given":"Jingsong","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Satellite Ocean Environment Dynamics, Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1531-5262","authenticated-orcid":false,"given":"Yijun","family":"He","sequence":"additional","affiliation":[{"name":"School of Marine Sciences, Nanjing University of Information Science and Technology, Nanjing 210044, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1016\/j.rse.2018.05.001","article-title":"Effect of wind direction and incidence angle on polarimetric SAR observations of slicked and unslicked sea surfaces","volume":"213","author":"Skrunes","year":"2018","journal-title":"Remote Sens.
