Abstract: A simplified acoustic Doppler wind sensor that can be built around an existing sounder is described. The instrument consists of two fan-beam transmitters and a pencil-beam receiver in an orthogonal configuration. Considerable ...

Abstract: This article describes a 96-channel computer-controlled data acquisition, processing and recording system designed for observational studies of turbulence structure in the atmospheric boundary layer. The system scans all ...

Abstract: The paper describes the general characteristics of a non-orthogonal sonic anemometer array. The effects of line-averaging and spatial separation (between mid-points of the horizontal paths) are analyzed and spatial transfer ...

Abstract: Comparisons between measurements of a wind component by a Doppler lidar and by a conventional anemometer are presented. The two measurement techniques provided thirteen 15 min data sets which agreed within 0.04 m s?1 on ...

Abstract: An experiment comparing turbulence statistics measured from a tower and from probes attached to the tethering cable of a large balloon is described. The results indicate that some important parameters can be measured with ...

Abstract: Results from a boundary layer experiment conducted over a flat site in northwestern Minnesota are discussed. Wind and temperature fluctuations near the ground were measured with AFCRL's fast-response instrumentation on a ...
