Error estimation of spectral parameters for high-resolution wind and turbulence measurements by wind profiler radars

Combining Microwave Radiometer and Wind Profiler Radar Measurements for High-Resolution Atmospheric Humidity Profiling

A self-consistent remote sensing physical method to retrieve atmospheric humidity high-resolution profiles by synergetic use of a microwave radiometer profiler (MWRP) and wind profiler radar (WPR) is illustrated. The proposed technique is based on the processing of WPR data for estimating the potential refractivity gradient profiles and their optimal combination with MWRP estimates of potential...

Conceptually New Approach to Wind Measurements by Spaced Receiver Radars

Spaced receiver (SR) radars have shown clear advantages over conventional Doppler beam swinging radars for the measurements of wind profiles at high temporal and spatial resolution. Several effective techniques for wind and turbulence measurements have been developed (Holloway et al. 1997, Cohn et al. 1997). These techniques provide a solution to the diffraction problem by either directly assum...

The Precision and Relative Accuracy of Profiler Wind Measurements

Two independent wind profiles were measured every hour during Februa j 1986 with a five-beam, UHF (405 MHz) wind Profiler at Platteville, Colorado. Our analysis of the horizontal wind components over all heights for the entire month gave a standard deviation of about 1.3 m s-' for the measurement errors one can expect for three-beam Profilers in clear air. This study demonstrated that it is imp...

Estimation of rain parameters from spectral moments of L-band wind profiler using Multi-Layer Perceptron Network model

Two Multi-Layer Perceptron (MLP) models are developed to estimate the radar reflectivity factor (dBZ) and rain intensity (R) from the spectral moments of an L-band wind profiler. Out of the four spectral moment inputs of the MLP models, the backscattered power (P) and Doppler velocity (VD) were found to have better correlation with the rain parameters. The model results were validated with the ...
