Abstract: Successive tetroon releases are utilized to provide an estimate of the lateral diffusion from a continuous point source as a function of downwind distance. On the average the tetroons yield a lateral standard deviation ...

Abstract: During May and early June of 1963, 88 tetroon-transponder flights were made at relatively low level in the Los Angeles Basin. Five different tetroon release sites were utilized, extending from Point Dume northwest of Los ...

Abstract: An analysis is presented of low-level trajectory data obtained by means of constant level balloon flights from Cape Hatteras, N.C., during September and October 1959. An approximately constant floating level was obtained ...

Abstract: During July 1964 more than 90 constant volume balloon (tetroon) flights were made from the area of Atlantic City, N.J., with the primary purpose of delineating the sea breeze regime at that locale. The transponder-equipped ...

Abstract: During January of 1960, eight tetroons (constant volume, super-pressured balloons were released from Wallops Island for flight at approximately 3000 ft. The tetroons were tracked by the very accurate AN/FPS-16 radar, thus ...

Abstract: Low-level, constant volume balloon (tetroon) flights made from Yucca Flat in the Nevada Proving Grounds of the Atomic Energy Commission are utilized to yield an estimate of the nature and magnitude of vertical air motions ...

Abstract: The dominant period of air parcel oscillation in the vertical within the planetary boundary layer is estimated from vertical velocity spectra derived from 40 constant volume balloon (tetroon) flights in the vicinity of the ...

Abstract: During July 1966, nearly 100 tetroon flights were made at the National Reactor Testing Station (NRTS), Idaho Falls, with the primary purpose of verifying the existence of longitudinal roll-vortices, or helices, in the ...

Abstract: Tetroon flights at heights near 300 m within the Los Angeles Basin illustrate the useful results to be derived from the use of Lagrangian probes in an urban environment. The tetroon trajectories depict air-flow reversals ...

Abstract: Constant-volume balloon (tetroon) flights tracked by radar across Columbus, Ohio, in March 1969, illustrate the effect of a city on the nighttime airflow at heights of 100?200 m. On the average, the urban influence on wind ...
