In coincidence with the airborne overpasses seaborne measurements of water leaving reflectance and water quality parameters were performed. In addition near-simultaneous satellite imagery are available. This paper deals with the analysis of the airborne data. The CASI data have been atmospherically corrected using the in-house software WATCOR which is based on the radiative transfer code MODTRAN-4 and takes into account atmospheric and air/water interface effects. The data are subsequently geometrically corrected with PARGE. A semi-analytical approach is used to retrieve the concentration of the water constituents: for chlorophyll determination a biooptically modelled red/NIR band ratio algorithm is applied to the data; to quantify the Suspended Particulate Matter a single band NIR algorithm, calibrated for the Belgian coastal waters is used. The results of these semi-analytical methods were compared to an analytical approach where the water quality parameters are retrieved from the subsurface irradiance reflectance spectra using a least square  determination of chlorophyll-a (CHL), suspended particulate matter (SPM) and colored dissolved organic matter (CDOM) and requires as input the inherent optical properties (IOPs) of (specific) absorption and backscattering of the water constituents.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Hyperspectral airborne remote sensing of the Belgian coastal waters","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2009-03-17","DateCreate":"2009-03-17","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":132277,"PubliDate":2005,"Pagination":"293-299","XtraPublOfAnaID":null,"ISBN":null,"Volume":null,"Issue":null,"BRefMon":132273,"BRefMonRR":"<b>Zagajewski, B.; Sobczak, M.; Wrzesien, M.
