The on of the Research Laboratories is t) study the oceans, inland waters, the lower and r atmosphere, the space environment, and the earth, in search of the under-A 1 ~m .;i~ l ed to provide more useful services in Improving man's prospects for survival v =as nflue by the physical environment. Laboratories contributing to these studies are:Erh nces Laoboratories: Gteomagnetism, seismology, geodesy, and related earth sc ences; quake processes, internal structure and accurate figure of the Earth, and / . dltributi dtthe Earth's mass. Aeronomy Laboratory: Theoretical, laboratory, rocket, and satellite studies of the physical and chemical processes controlling the ionosphere and exosphere of the earth and other planets.Wave Propagation Laboratory: Development of new methods for remote sensing of the geophysical environment; special emphasis on propagation of sound waves, and electromagnetic waves at millimeter, infrared, and optical frequencies.Institute for Telecommunication Sciences: Central federal agency for research and servIces in propagation of radio waves, radio properties of the earth and its atmosphere, nature of radio noise and interference, information transmission and antennas, and methods for the more effective use of the radio spectrum for telecommunications. "Research Flight Facility: Outfits and operates aircraft specially instrumented for research; and meets needs of ESSA and other groups for environmental measurements for aircraft.
