In this paper, the effect of OOB response on the radiometric measurements made just above the sea surface is evaluated for the three broad visible bands (i.e., blue, green, and red) of the Coastal Zone Imager (CZI) onboard China\u2019s ocean satellite HY-1C to be launched in September 2018. For the turbid coastal (Case 2) waters whose optical properties are mainly dominated by suspended sediment and colored dissolved organic material, the OOB effect can be neglected (&lt;2%) for all three CZI visible bands. For the phytoplankton-dominated (Case 1) waters which are mainly distributed in the clear open ocean, a significant (&gt;2%) OOB effect was found in the green band over oligotrophic waters (chlorophyll a concentration \u2264~0.1 mg\/m3), and accordingly a model based on the CZI blue-green band ratio is proposed to correct this effect. The OOB influence on the CZI ocean color retrieval is discussed. This research highlights the importance of the comprehensive pre-launch radiometric characterization and the OOB effect correction for the broad band space-borne sensor, in order to achieve a high-quality quantitative ocean product.<\/jats:p>","DOI":"10.3390\/s18093067","type":"journal-article","created":{"date-parts":[[2018,9,12]],"date-time":"2018-09-12T10:26:36Z","timestamp":1536747996000},"page":"3067","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Out-of-Band Response for the Coastal Zone Imager (CZI) Onboard China\u2019s Ocean Color Satellite HY-1C: Effect on the Observation Just above the Sea Surface"],"prefix":"10.3390","volume":"18","author":[{"given":"Tingwei","family":"Cui","sequence":"first","affiliation":[{"name":"First Institute of Oceanography, State Oceanic Administration, Qingdao 266061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Ding","sequence":"additional","affiliation":[{"name":"National Satellite Ocean Application Service, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fujuan","family":"Jia","sequence":"additional","affiliation":[{"name":"Beijing Institute of Space Mechanics &amp; Electricity, Beijing 100190, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bing","family":"Mu","sequence":"additional","affiliation":[{"name":"Department of Physics, Ocean University of China, Qingdao 266071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rongjie","family":"Liu","sequence":"additional","affiliation":[{"name":"First Institute of Oceanography, State Oceanic Administration, Qingdao 266061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengmei","family":"Xu","sequence":"additional","affiliation":[{"name":"Beijing Institute of Space Mechanics &amp; Electricity, Beijing 100190, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianqiang","family":"Liu","sequence":"additional","affiliation":[{"name":"National Satellite Ocean Application Service, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Zhang","sequence":"additional","affiliation":[{"name":"First Institute of Oceanography, State Oceanic Administration, Qingdao 266061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"725","DOI":"10.2112\/SI73-124.1","article-title":"Sea Areas Reclamation and Coastline Change Monitoring by Remote Sensing in Coastal Zone of Liaoning in China","volume":"73","author":"Suo","year":"2015","journal-title":"J.
