Abstract

SeaWiFS (sea-viewing wide field-of-view sensor) has been designed by NASA (National Aeronautics and Space Administration) for the qualitative and quantitative estimation of materials suspended and dissolved in the upper layers of the oceans (chlorophyll, sediment, yellow substance). SeaWiFS, characterized by 8 channels in the region between 400 and 900 nm, when compared with the former CZCS (costal zone calor scanner) shows a higher signal to noise ratio (ranging from 450 to 700), a lower sensivity to polarization (lower than 2%) and a higher number of channels applicable for a more effective atmospheric correction of data.

In this work the SeaWiFS technical features are given, elements on data application are introduced and major techniques adopted for calibration of data and validation of derived products are shortly discussed. .
