Resumo

In this paper the feasibility of estimating the chlorophyll content of ocean waters through the use of multispectral remote sensors on board of orbiting satellites, is discussed. Some aspects of the physical foundations of the interaction processes of visible light (380-770 nm) with the atmosphere and liquid mass and some models for this detection, are also discussed.

SYNOPSIS

In this paper the feasibility of estimating the chlorophyll content of ocean waters through the use of multispectral remote sensors on board of orbiting satellites, is discussed. Some aspects of the physical foundations of the interaction processes of visible light (380-770 nm) with the atmosphere and liquid mass and some models for this detection, are also discussed.
