Calibration of the ocean color and temperature scanner
IEEE Transactions on Geoscience and Remote Sensing, 1999Calibration results of the ocean color and temperature scanner (OCTS) on board the Advanced Earth Observing Satellite (ADEOS) are presented. The authors have evaluated the OCTS responses to internal calibration sources (i.e., lamps, electric voltages, and sunlight), natural targets (i.e., night data and uniform targets in the daytime), external ...

VIIRS ocean color research and applications
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015In this paper, we provide evaluations and assessments of the Visible Infrared Imaging Radiometer Suite (VIIRS) ocean color products, including normalized water-leaving radiance spectra nL w (λ) at VIIRS five spectral bands, chlorophyll-a concentration (Chl-a), water diffuse attenuation coefficients at the wavelength of 490 nm, K d (490), and at the ...

Applications of satellite ocean color products
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017In this paper, we provide an overview of ocean color products derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-orbiting Partnership (SNPP), which was launched on October 28, 2011. VIIRS ocean color products include normalized water-leaving radiance spectra nL w (λ) at VIIRS five spectral bands ...

Influence of oceanic whitecaps on atmospheric correction of ocean-color sensors
Applied Optics, 1994The effects of oceanic whitecaps on ocean-color imagery are simulated and inserted into the proposed Sea-Viewing Wide-Field-of-View Sensor (SeaWiFS) atmospheric-correction algorithm to understand its tolerance to error in the estimated whitecap contribution.

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.

From Cells to the Ocean: Satellite Ocean Color
1991Variations in the color of the ocean as seen from space are principally due to variations in the concentration and optical properties of biogenic materials, dissolved and particulate, in the upper ocean. From 1978 to 1986 the NIMBUS-7 Coastal Zone Color Scanner observed these variations over the global ocean; the wealth of data that has resulted is ...

Effects of Winds on Ocean Color
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006Previous studies suggested that winds would indirectly affect the remote sensing of ocean color. Moderately roughened sea enhances the probability of specular reflection of solar disk by randomly orientated wave facets. Whitecaps due to breaking waves increase the diffuse reflectance of sea surface and hence radiant energy received at a color sensor ...

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.

SPIE Proceedings, 1998
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.

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.
