Rayleigh Scattering

colour

rayleigh_scattering(wavelength[, …])	Returns the Rayleigh optical depth \(T_r(\lambda)\) as function of wavelength \(\lambda\) in centimeters (cm).
rayleigh_scattering_spd([shape, …])	Returns the Rayleigh spectral power distribution for given spectral shape.
scattering_cross_section(wavelength[, …])	Returns the scattering cross section per molecule \(\sigma\) of dry air as function of wavelength \(\lambda\) in centimeters (cm) using given \(CO_2\) concentration in parts per million (ppm) and temperature \(T[K]\) in kelvin degrees following Van de Hulst (1957) method.
