Abstract: A method is described and evaluated for decreasing artifacts in radar wind profiler data resulting from overflying, migrating birds. The method processes the prerecorded, averaged spectral data of a wind profiler to derive ...

Abstract: Measurements of acoustic backscatter in the lower planetary boundary layer and optical line-of-sight scintillation in the surface layer are each used to compute sensible heat fluxes in the unstable surface layer. Comparisons ...

Abstract: Temperature and velocity fluctuations within a cooling tower plume in stable conditions at the Keystone power plant in Pennsylvania have been measured by use of a calibrated sodar. Monostatic and bistatic systems probed ...

Abstract: Measurements in a tributary to Brush Creek Valley during the September and October 1984 ASCOT campaign with laser anemometers, tethersondes, a minisodar, and smoke release were used to calculate the contribution by tributaries ...

Abstract: Ground based lidar measurements of the atmospheric mixed layer depth, the entrainment zone depth and the wind speed and wind direction were used to test various parameterized entrainment models of mixed layer growth rate. ...

Abstract: Measurements of raindrop fall velocity spectra have been made with a minisodar. Amplitude calibration of the system enables the calculation of drop size parameters such as number density, water density, and surface area ...

Abstract: Simultaneous measurements of CT2 and CV2 were made using a calibrated Doppler sodar and a research aircraft equipped with meteorological and turbulence sensors. In each experiment a region of specific interest was identified ...

Abstract: A model framework for parameterized subgrid-scale surface fluxes (PASS) has been modified and applied as PASS1 to use satellite data, models, and limited surface observations to infer root-zone available moisture (RAM) ...

Abstract: Lidar observations of clear-air convection during the 1983 Boundary Layer Experiment (BLX83) reveal the presence of elongated, parallel regions of updrafts marked by enhanced aerosol backscattering. These linear (banded) ...

Abstract: The authors compared methods for estimating surface fluxes under clear-sky conditions over a large heterogeneous area from a limited number of ground measurements and from satellite observations using data obtained from ...
