Optical transmission through the atmosphere is degraded both by the turbulence-induced fluctuation of the optical index, described by Cn², the turbulence structure constant for index, and also by extinction due to molecular absorption and scattering by fog or aerosols. Various techniques for direct optical measurement of Cn² and extinction are compared and the results shown to depend differently on the distribution of turbulence along the path. Tech- niques of field optical measurements of Cn² and extinction coefficient developed at NPS are presented. Results are compared with thermal and humidity fluctuations, and Knollenberg particle size spectra.
