WebThe transmission T and "optical depth" t of an atmospheric constituent are related as follows: T = Exp (-t*m) , or t = - ln (T)/m, where m is the airmass, or equivalent path length through the atmosphere. In simplest terms, for Io = extraterrestrial radiation, and I = radiation at surface I = Io * ( Tw*To*Tg*Tr*Ta) In physics, optical depth or optical thickness is the natural logarithm of the ratio of incident to transmitted radiant power through a material. Thus, the larger the optical depth, the smaller the amount of transmitted radiant power through the material. Spectral optical depth or spectral optical thickness is the natural … See more Attenuation Optical depth measures the attenuation of the transmitted radiant power in a material. Attenuation can be caused by absorption, but also reflection, scattering, and other physical … See more Atomic physics In atomic physics, the spectral optical depth of a cloud of atoms can be calculated from the quantum-mechanical properties of the … See more • Optical depth equations See more • Air mass (astronomy) • Absorptance • Actinometer • Aerosol • Angstrom exponent • Attenuation coefficient See more
WebApr 8, 2024 · Optical density (O.D.) = log₁₀ Io / It. The optical density of any medium is defined as the logarithmic ratio of the intensity of incident light (Io) to the intensity of the transmitted light (It) passing through that medium. The O.D value for absorbance can be computed by the formula given by, O.D. Value. Absorbance (A) = log₁₀ (100 ... WebOptical depth is a measure of the amount of electromagnetic radiation that is absorbed in passing through a medium—e.g., a cloud, the atmosphere of a planet, or a region of particles in space. It thus serves… Read More
