Optical Phenomena¶
Rayleigh Scattering¶
colour
rayleigh_scattering (wavelength[, …]) |
Returns the Rayleigh optical depth \(T_r(\lambda)\) as function of wavelength \(\lambda\) in centimeters (cm). |
sd_rayleigh_scattering ([shape, …]) |
Returns the Rayleigh spectral 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. |
