WebNov 1, 1999 · The results of these calculations are shown in Table 2, where the change of optical depth Δτ(H 2 O) is given for the case where dry air molecules are replaced by H 2 O molecules for 44 kg m −2 column water vapor. Thus for a Rayleigh optical depth of 1.224 for air at 300 nm, a CO 2 concentration of 360 ppm would contribute an optical depth ... 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.
