The objective of this research was to evaluate a Doppler laser remote sensor (lidar) in the measurement of mean wind and the temporal and spatial distribution of convective elements and other perturbation features Convective wind fields as investigated with Doppler lidar book the planetary boundary layer.

Dual-Doppler lidar observations are used to assess the accuracy of single-Doppler retrievals of microscale wind and temperature fields in a shear-driven convective boundary layer.

The retrieval algorithm, which is based on four-dimensional variational data assimilation, is applied by using dual- and single-Doppler lidar data that are acquired Cited by: [1] Dual-Doppler lidar and heliborne sensors were used to investigate the three-dimensional (3D) structure of the wind field over Sendai Airport in June The 3D structures of several-hundred-meter-scale horizontal convective rolls (HCRs) in the sea-breeze layer were observed by the dual-Doppler lidar.

The scale of the HCRs determined byCited by:   Abstract. We utilized a Doppler lidar to measure spectra of vertical velocity w from m above the surface to the top of the daytime convective boundary layer (CBL).

The high resolution 2μm wavelength Doppler lidar developed by the NOAA Environmental Technology Laboratory was used to detect the mean radial velocity of aerosol by: From August to Marchwe conducted WINPOD-L (WINd Power Observation by Doppler-Lidar) field project to measure the offshore wind power.

One vertically pointing Doppler lidar for vertical wind measurements and profiling of its higher-order moments. It may be possible to perform these measurements with a single Doppler lidar by switching between vertical and VAD operation modes, if the SNR is high enough.

This would need to be investigated by studying the performance. measurements of velocity spectra in the convective bound-ary layer using a staring lidar. Spatial averaging along the line-of-sight was modeled using a spectral transfer function, and an attempt was made to recover the true atmospheric spectra by observing inertial sub-range isotropy.

Frehlich et al. [] investigated wind field statistics. wind field characterization at high spatial and temporal resolution but also holds prospects as tools for calibrating traditional point-monitoring anemometric devices which currently is investigated.

The height of the convective boundary layer (CBL) is estimated using the 2 micron Doppler lidar ‘WindTracer '. The instrument provides an along-beam-resolution with independent range gates of 72 m length, and a temporal resolution of 1 Hz (accumulating pulses).

Two sets of automatically working algorithms were implemented, one based on aerosol backscatter, the second on vertical wind.

The airborne Doppler lidar based on the Lockheed Martin WindTracer WTX made its first measurement aboard the Dornier D-IBUF in July A total of 4 flights were performed to explore the system performance under various flight conditions and measure boundary layer wind profiles and turbulence under convective conditions.

Abstract. Results on the structure of the convective atmospheric boundary layer based on the analyses of data from the instrumented NSSL-KTVY tower, airborne Doppler lidar, and ground-based Doppler radars are presented. By combining the two “WindTracer systems dual-Doppler techniques and thus a comprehensive representation of 3rd dimensional wind fields become onally the precise wind measurements of the LIDAR network can be used for the evaluation of model results and the applicability of current scientific methods.
