Satellite remote sensing is widely used in the retrieval of marine phytoplankton over a wide range and long time series, but not yet for taxonomical composition. In this study, we used coincident in situ measurement data from high-performance liquid chromatography (HPLC) and remote sensing reflectance (Rrs) to investigate the empirical relationships between phytoplankton groups and satellite measurements. A nonparametric model, generalized additive model (GAM), is introduced to establish inversion models of various marine phytoplankton groups. Seven inversion models (two sizes classes among the microphytoplankton and nanophytoplankton and four groups among the diatoms, dinoflagellates, chrysophytes, and cryptophytes) are applied to the South China Sea (SCS) for 2020, and satellite images of phytoplankton sizes and groups are presented. Microphytoplankton prevails in the coastal and continental shelf, and nanophytoplankton prevails in oligotrophic oceans. Among them, the dominant contribution of microphytoplankton comes from diatoms, and nanophytoplankton comes from chrysophytes. Diatoms (nearshore) and chrysophytes (outside the continental shelf) are the dominant groups in the SCS throughout the year. Dinoflagellates only become dominant in some coastal areas, while cryptophytes rarely become dominant.<\/jats:p>","DOI":"10.3390\/rs14133037","type":"journal-article","created":{"date-parts":[[2022,6,26]],"date-time":"2022-06-26T22:50:23Z","timestamp":1656283823000},"page":"3037","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Remote Sensing of Marine Phytoplankton Sizes and Groups Based on the Generalized Addictive Model (GAM)"],"prefix":"10.3390","volume":"14","author":[{"given":"Yuchao","family":"Wang","sequence":"first","affiliation":[{"name":"School of Marine Sciences, Sun Yat-sen University, Guangzhou 510006, China"}]},{"given":"Fenfen","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Marine Sciences, Sun Yat-sen University, Guangzhou 510006, China"},{"name":"Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai), Zhuhai 519082, China"},{"name":"Guangdong Provincial Key Laboratory of Marine Resources and Coastal Engineering, School of Marine Sciences, Sun Yat-sen University, Zhuhai 519082, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"200","DOI":"10.1126\/science.281.5374.200","article-title":"Biogeochemical controls and feedbacks on ocean primary production","volume":"281","author":"Falkowski","year":"1998","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"237","DOI":"10.1126\/science.281.5374.237","article-title":"Primary production of the biosphere: Integrating terrestrial and oceanic components","volume":"281","author":"Field","year":"1998","journal-title":"Science"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"591","DOI":"10.1038\/nature09268","article-title":"Global phytoplankton decline over the past century","volume":"466","author":"Boyce","year":"2010","journal-title":"Nature"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"782","DOI":"10.1038\/nrmicro1747","article-title":"Microbial structuring of marine ecosystems","volume":"5","author":"Azam","year":"2007","journal-title":"Nat.
