Evaluating the performance of the OC5 algorithm of IFREMER for the highly turbid waters of Río de la Plata
Remote sensing provides a global vision of the oceans; validation is, however, an essential previous step. IFREMER developed the empirical algorithm OC5 for highly turbid (or type 2) waters and it performed well for the northwestern European shelf. The aim of this study was to evaluate the perform...
