Abstract

An experimental investigation was made to determine the general characteristics of the spectral transmission of the atmosphere in the vicinity of Washington, D. C, on the Chesapeake Bay, in the Gulf of Mexico, and in the Central Pacific. Transmission measurements were made at the wavelengths of approximately 15 of the Hg discharge lines in the interval 2500A to 6000A. Values of the spectral atmospheric attenuation coefficients (km⁻¹) have been computed. For all observations made, these values increase toward shorter wavelengths and this is most pronounced for wavelengths below 3200A, where true absorption as well as scattering contributes to the attenuation.
