Abstract: It is suggested that Eulerian mean velocities and eddy fluxes are not necessarily identical with those observed by (quasi-Lagrangian) GHOST balloons. Although a general relationship between the two sets of variables has ...

Abstract: An evaluation is made of the typical variation with height and time of mean and eddy flow of momentum in the atmospheric boundary layer using carefully determined wind profile data obtained over a separation of 200 m in a ...

Abstract: During the summer of 1961, the vertical transfer of water vapor and sensible heat was determined at a height of 4 m over an irrigated field at Davis, Calif. Simultaneous determinations of evaporation at the surface were ...

Abstract: The Evapotron, an instrument designed to measure vertical fluxes of heat and water vapor in the lower atmosphere, is described. Completely transistorized, the instrument consumes 50?100 watts and can be operated by a ...

Abstract: As a result of experience gained with the Evapotron in the measurement of eddy fluxes, a new instrument called the Fluxatron has been developed. The computing efficiency has been improved by filtering out slow eddies which ...

Abstract: The results of a heat flux comparison experiment carried out at Hay, New South Wales, Australia, during May 1966 using a sonic anemometer thermometer (SAT), Fluxatron and Evapotron are reported. The instruments agree with ...
