A matrix operator method (Plass et al, 1973a, 1973b; Kattawar et al, 1980) has been developed which calculates accurately the radiance and irradiance based on an atmosphere-ocean model. The reflection and refraction of the radiation at the ocean surface is taken into account.

Costal Zone Color Scanner (CZCS) was the first of its kind sensor flown in 1978 for ocean studies. It gave quantitative estimate of phytoplankton. After that, many missions were launched by various agencies like IRS-P3-MOS, Sea-WiFS, OCTS, MODIS, MERIS etc.

The oceans cover over 70% of the earth’s surface and the life inhabiting the oceans play an important role in shaping the earth’s climate. Phytoplankton, the microscopic organisms in the surface ocean, are responsible for half of the photosynthesis on the planet.

In-water and remote measurements of ocean color
Boundary-Layer Meteorology, 1980Spectral measurements of downwelling irradiance, Ed(λ), above the surface, and of upwelling irradiance just below the surface, Eu(λ), allow computation of spectral values of the diffuse reflectance R(λ) = Eu(λ)/Ed(λ); this yields full information about the true color and brightness of the ocean.

An Ocean Color CCD Imager (OCCI) has been developed. It has three bands with nominal spectral region 430nm-520nm, 580nm- 670nm and 760nm-860nm. It is composed of three separate subsystem, each for one band, which have the same structure and operate in push-broom mode with 1024-pixel linear array CCD detectors.

Advances in radiometry for ocean color
SPIE Proceedings, 2003Organic materials in the oceans have spectral signatures based on their light-scattering properties. These optical properties are related to bio-physical and bio-chemical data products such as the concentration of phytoplankton chlorophyll-α through bio-optical algorithms.

Ocean color through satellite lidars: the COLOR project
2023During the last decade, new applications exploiting data from satellite borne lidar measurements demonstrated that these sensors can give valuable information about ocean optical properties [1,2,3]. Within this framework, COLOR (CDOM-proxy retrieval from aeOLus ObseRvations) consisted in a 18-month feasibility study approved by ESA within the Aeolus ...

Remote sensing of ocean color offers the potential of monitoring some of the characteristics of the upper layer of the ocean, on a global basis, by use of sensors on satellites or aircraft. Color sensing has been shown to be of use for parameters such as chlorophyll and sediment concentration and the location and motion of pollutants due to ocean ...
