Before using these data, however, the measurements need to be validated. Based on the in situ buoy data from the National Data Buoy Center (NDBC) and the Jason-2 altimeter data, the HY-2 Ku-band significant wave height (SWH) measurements were validated. The comparisons showed that a linear regression with NDBC measurements can be used to improve the accuracy of the HY-2 SWH measurements. Compared with the NDBC SWH data, the validation results of the HY-2 SWH data show an RMS (root mean square) of 0.33 m, which is similar to that of the Jason-1 and Jason-2 data; the RMS of the HY-2 SWH is 0.30 m, which, corrected via linear regression, is similar to that of the corrected Jason-1 and Jason-2 data (0.27 m and 0.23 m, respectively). Therefore, the accuracy of the HY-2 SWH products is close to that of the Jason-1\/2 SWH data.<\/jats:p>","DOI":"10.3390\/rs9101016","type":"journal-article","created":{"date-parts":[[2017,10,2]],"date-time":"2017-10-02T13:10:05Z","timestamp":1506949805000},"page":"1016","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Validation of the Significant Wave Height Product of HY-2 Altimeter"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4447-721X","authenticated-orcid":false,"given":"Chuntao","family":"Chen","sequence":"first","affiliation":[{"name":"National Ocean Technology Center, State Oceanic Administration, Tianjin 300112, China"}]},{"given":"Jianhua","family":"Zhu","sequence":"additional","affiliation":[{"name":"National Ocean Technology Center, State Oceanic Administration, Tianjin 300112, China"}]},{"given":"Mingsen","family":"Lin","sequence":"additional","affiliation":[{"name":"National Satellite Ocean Application Service, State Oceanic Administration, Beijing 100081, China"}]},{"given":"Yili","family":"Zhao","sequence":"additional","affiliation":[{"name":"National Ocean Technology Center, State Oceanic Administration, Tianjin 300112, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4084-936X","authenticated-orcid":false,"given":"He","family":"Wang","sequence":"additional","affiliation":[{"name":"National Ocean Technology Center, State Oceanic Administration, Tianjin 300112, China"}]},{"given":"Jin","family":"Wang","sequence":"additional","affiliation":[{"name":"Qingdao University, Qingdao 266003, China"}]}],"member":"1968","published-online":{"date-parts":[[2017,9,30]]},"reference":[{"key":"ref_1","unstructured":"Fang, M.Q.
