Optical properties of pure water
WebOct 5, 2011 · The optical properties of sea water are sometimes grouped into inherent and apparent properties. •. Inherent optical properties (IOPs) are those properties that depend … WebSeasonal differences in the spectral shape of Rrs were contributed to by eukaryotic phytoplankton a, colored dissolved organic matter (CDOM) a, and non-phytoplankton bb. In addition, we used bio-optical models based on chlorophyll concentration to simulate optical properties and interpreted deviations of our measurements from the model results.

WebThis definition only implies that the optical properties, especially scattering and absorption, are only determined by molecules or ions. Though the problems of scattering and absorption of pure water belongs to physical chemistry, it is also of interest in optical oceanography. As is well known, the waters of the open ocean, particularly the ... The absorption spectrum of pure water is used in numerous applications, including light scattering and absorption by icecrystals and cloud water droplets, theories of the rainbow, determination of the single-scattering albedo, ocean color, and many others. Quantitative description of the refraction index[edit] See more The refractive index of water at 20 °C for visible light is 1.33. The refractive index of normal ice is 1.31 (from List of refractive indices). In general, an index of refraction is a complex number with real and imaginary parts, … See more • Absorption (electromagnetic radiation) • Atmospheric radiative transfer codes • Color of water • Electromagnetic absorption by water See more Over the wavelengths from 0.2 μm to 1.2 μm, and over temperatures from −12 °C to 500 °C, the real part of the index of refraction of water … See more In the above formula, the density of water also varies with temperature and is defined by: See more
