摘要: A recent determination by D. R. Bates of the Rayleigh scattering cross section (σRS) for air from 0.2 to 1 μm leads a simple empirical formula (λ in μm) σRS = 4.02 × 10−28λ4+xcm2 where x 0.389λ + 0.09426λ − 0.3228 spectral region < λ 0.55 ; accuracy is within ±0.5%. From visible at infrared (i.r.) μm, same can be obtained using constant value, 0.04. The accounts degree depolarization which varies with wavelength according latest Bates.
