'.-. The NBS Boulder Laboratories in Colorado, housing the radio propagation, radio astronomy, and radio standards laboratories. In the background, on the first rise of the foothills of the Rockies, are the Bureau's cryogenic laboratories.
474 THE NEW WORLD OF SCIENCE (1946-5i) and commercial radio, as the central agency of the Nation for basic research in the propagation of radio waves.124 Besides continuing operation of the worldwide chain of stations—the total number was 58, of which 14 were directly operated or supported by the Bureau—to provide prediction services for long-distance radio, CRPL took over the research functions of the radio section of the Bureau's electrical division. It at once undertook extension of the research in lower frequencies into the ultrahigh frequency and microwave region (3000 megacycles or more) for the new fields of television, of frequency modulation (FM) broad- casting, and military and commercial radar. Severely limiting the range and minimum usable signals in FM broad. casting, television, and other very-high-frequency services, the Bureau found, was the noise associated with cosmic and solar radio waves reaching earth from outer space. To study these phenomena, the Bureau instituted a pro. gram in radio astronomy, setting up at Boulder two solar radiometers with mirrors 25 feet in diameter, operating at different frequencies, to track the sun and observe its outbursts of radio energy.125 While outer space phenomena produced measurable limitations on very:high.frequency transmission, the major influences on propagation at microwave frequencies proved to 'be nearer to earth. Studies in tropospheric meteorology and terrain geometry—that is, the effects of rain and trees and hills—first begun several decades earlier for ordinary radio transmission, were resumed in order to learn the causes of attenuation of very short micro- waves, particularly those used in radio relay operations.126 Both the radio astronomy program and that on the troposphere became long-range projects. An innovation in the radio services of the Bureau, begun on October 3, 1945, shortly before setting up CRPL, was the shortwave broadcast of standard time signals each 5 minutes around the clock. It augmented the standard radio frequencies, standard time intervals or pulses, standard audio frequen- Hearings * * 1948 (Mar. 12, 1947), p. 339. Establishment of CRPL was authorized in letter, Secretary of Commerce Wallace to Secretary of the Treasury, Jan. 9, 1946 (copy in NBS Historical File), and activated as a division of the Bureau by memo, Director, for Division and Section Chiefs, NBS, Apr. 19, 194.6 ("General Correspondence Files of the Director, 1945—1955"). NBS Annual Report 1948, p. 247. The new branch of science, radio astronomy, had its beginnings in 1932 when Karl G. Jansky of the Bell Telephone Laboratories described the reception of extraterrestrial radio waves and from their diurnal variation in direction tentatively identified their source in the Milky Way. See Proc. IRE, 20, 1920 (1932) Nature, 132, 66 (1933). Grote Reber, both before and after he came to the Bureau in the 1940's, and the Bureau's chief of radio research, Dellinger, were to extend these observations. See F. T. Haddock, "Introduction to radio astronomy," Proc. IRE, 46, 3 (1958). NBS Annual Report 1949, p. 71.
