The method was applied under widely varying solar elevation and weather. Noise due to reflected sky light was evaluated by theory on surface waves and by field data. A strong relationship was established for the shallow and eutrophic freshwater IJssel Lagoon including the River IJssel (The Netherlands) between corrected Chl-<i>a</i> concentrations (3-185 mg m<sup>-</sup><sup>3</sup>) and the reflectance ratio for 704 and 672 nm with backscattering derived from the reflectance at 776 nm (<i>R</i><sup>2</sup> > 0.95; <i>N </i>= 114; standard error of estimate <9 mg m<sup>-</sup><sup>3</sup>). This relationship adequately predicted Chl-<i>a</i> concentrations in well-mixed and optically deep water in lakes in The Netherlands, the Scheldt Estuary in Belgium and The Netherlands, and Lake Tai in China (<i>N</i> = 40; standard error of estimate <9 mg m<sup>-</sup><sup>3</sup>). Floating layers of the cyanobacterium <i>Microcystis</i> in Lake Chao in China were distinguished from homogeneously distributed phytoplankton by reflectance in the violet, blue, and near-infrared wavebands.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Optical teledetection of chlorophyll <i>a</i> in turbid inland waters","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:31:50.583659","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1999,"MonPub":null,"DateUpdate":"2014-04-03","DateCreate":"2012-09-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000079543100040","VABBcode":null,"OpenAcc":0,"DOI":"10.1021/es9809657"},"refs":null,"anarec":{"AnaID":217971,"PubliDate":1999,"Pagination":"1127-1132","XtraPublOfAnaID":null,"ISBN":null,"Volume":"33","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42837,"SerRR":"Environmental Science and Technology.
