Description:A variety of telescopes, used for studying the influence of the atmosphere on radio astronomy observations, surround the Beard House in Green Bank in summer 1962. The elevated dish on the right is the 20 foot parabolic antenna, installed in June 1962 to detect radiation from water in atmospheric vapor clouds and rain on a wavelength of about 6 cm. The "Sugar Scoop" on the left is the 4 foot parabolic horn reflector antenna for detecting similar radiation at 3 cm. The third dish is the 12 foot parabolic antenna used earlier for investigations at 3.75 cm. The results of the investigations were expected to influence the choice of suitable frequency for a proposed very large antenna. [show more]
