Radiosonde
notes: label: Description
content: The National Bureau of Standards transferred this unmarked radiosonde to the Smithsonian in 1962, describing it as an experimental instrument from the late 1930s. The cylindrical tube, 15 cm in diameter and 34 cm long, is made of corrugated paper with a reflective painted surface and houses the transmitter and clock. Projecting above is a housing containing sensing elements for pressure (aneroid) and humidity (goldbeater's skin). The temperature element is missing. This radiosonde was probably associated with two N.B.S. physicists: Allen Varley Astin (1904-1984) and L. F. Curtis.
