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) 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 ...
