Measurement of water reflectance requires the measurement of water-leaving radiance and downwelling irradiance just above water. For the former there are four generic families of method, based on: (1) underwater radiometry at fixed depths; or (2) underwater radiometry with vertical profiling; or (3) above-water radiometry with skyglint correction; or (4) on-water radiometry with skylight blocked. Each method is described generically in the FRM context with reference to the measurement equation, documented implementations and the intra-method diversity of deployment platform and practice. Ideal measurement conditions are stated, practical recommendations are provided on best practice and guidelines for estimating the measurement uncertainty are provided for each protocol-related component of the measurement uncertainty budget. The state of the art for measurement of water-leaving radiance is summarized, future perspectives are outlined, and the question of which method is best adapted to various circumstances (water type, wavelength) is discussed. This review is based on practice and papers of the aquatic optics community for the validation of water reflectance estimated from satellite data but can be relevant also for other applications such as the development or validation of algorithms for remote-sensing estimation of water constituents including chlorophyll a concentration, inherent optical properties and related products.<\/jats:p>","DOI":"10.3390\/rs11192198","type":"journal-article","created":{"date-parts":[[2019,9,20]],"date-time":"2019-09-20T10:48:14Z","timestamp":1568976494000},"page":"2198","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":87,"title":["A Review of Protocols for Fiducial Reference Measurements of Water-Leaving Radiance for Validation of Satellite Remote-Sensing Data over Water"],"prefix":"10.3390","volume":"11","author":[{"given":"Kevin G.","family":"Ruddick","sequence":"first","affiliation":[{"name":"Royal Belgian Institute of Natural Sciences (RBINS), Operational Directorate Natural Environment, 29 Rue Vautierstraat, 1000 Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7860-5080","authenticated-orcid":false,"given":"Kenneth","family":"Voss","sequence":"additional","affiliation":[{"name":"Physics Department, University of Miami, Coral Gables, FL 33124, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8334-9595","authenticated-orcid":false,"given":"Emmanuel","family":"Boss","sequence":"additional","affiliation":[{"name":"School of Marine Sciences, University of Maine, Orono, ME 04469, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6069-1574","authenticated-orcid":false,"given":"Alexandre","family":"Castagna","sequence":"additional","affiliation":[{"name":"Protistology and Aquatic Ecology Research Group, Gent University, Krijgslaan 281, 9000 Gent, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4770-389X","authenticated-orcid":false,"given":"Robert","family":"Frouin","sequence":"additional","affiliation":[{"name":"Scripps Institution of Oceanography, University of California San Diego, 9500 Gilman Drive #0224, La Jolla, CA 92093-0224, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex","family":"Gilerson","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, The City College of New York, 160 Convent Avenue, New York, NY 10031, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6066-1562","authenticated-orcid":false,"given":"Martin","family":"Hieronymi","sequence":"additional","affiliation":[{"name":"Institute of Coastal Research, Helmholtz-Zentrum Geesthacht (HZG), Max-Planck-Str. 1, 21502 Geesthacht, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1045-663X","authenticated-orcid":false,"given":"B.
