Abstract: A radio-controlled air sampling system was developed for sampling tracer gases at an array of remote, portable sampling stations. Each sampling station contains a receiver-decoder, a battery pack and three evacuated metal ...

Abstract: About 700 cases of wind direction meander occurred in a three-year period during onshore flow at a Long Island coastal site. Most appeared to be caused by internal gravity waves but some by roll vortices. Each case was ...

Abstract: A study of the atmospheric transport and diffusion climatology of the United States east and Gulf coasts was conducted to aid in planning and site selection for potentially polluting installations. This paper presents ...

Abstract: Dispersion and deposition of ragweed pollen released naturally from circular area sources of four sizes (5?27 m in diameter) and artificially from point sources were studied at Brookhaven National Laboratory. Concentrations ...

Abstract: Experiments were conducted to investigate the differences in diffusion from an obstacle to free air flow in the ocean and from an undisturbed ocean site. A small island was used as the obstacle and simultaneous releases ...

Abstract: Pollen transport and dispersion from generalized area sources was studied by 29 flights to distances of 100 km and heights of 3 km using an aircraft-mounted isokinetic sampler. Tree pollens and ragweed pollen served as ...

Abstract: A research program is in progress at Brookhaven National Laboratory to determine the nature of atmospheric diffusion from a representative oceanic site, to relate observed diffusion patterns to meteorological and oceanographic ...
