Quality Control of Antenna Alignment and Receiver Calibration Using the Sun: Adaptation to Midrange Weather Radar Observations at Low Elevation Angles
Publisher: American Meteorological Society
Abstract: quality control method for combined online monitoring of weather radar antenna pointing biases and receiver calibration using solar signals detected by an operational radar is adapted for application to midrange radar data ...
Intercomparison and Potential Synergies of Three Methods for Weather Radar Antenna Pointing Assessment
Publisher: American Meteorological Society
Abstract: hree methods for estimation of the weather radar antenna azimuth and elevation pointing offsets are compared. Two of the methods reviewed use the known location of the sun as a reference. The first of these methods is based ...
The Sensitivity of Single Polarization Weather Radar Beam Blockage Correction to Variability in the Vertical Refractivity Gradient
Publisher: American Meteorological Society
Abstract: Radars operating in complex orographic areas usually suffer from partial or total beam blockage by surrounding targets at their lowest elevation scans. The need for radar quantitative precipitation estimates in such ...
Modeling Raindrop Size Distribution and Z(R) Relations in the Western Mediterranean Area
Publisher: American Meteorological Society
Abstract: This study shows the results of the modeling of drop size distributions (DSD) observed during a 2-yr study in Barcelona. Thirty-second individual sample collections of drop sizes and velocities were measured with an optical ...
Correction of Dual-PRF Doppler Velocity Outliers in the Presence of Aliasing
Publisher: American Meteorological Society
Abstract: AbstractIn Doppler weather radars, the presence of unfolding errors or outliers is a well-known quality issue for radial velocity fields estimated using the dual?pulse repetition frequency (PRF) technique. Postprocessing ...
How Robust Are Trends in the Brewer–Dobson Circulation Derived from Observed Stratospheric Temperatures?
Publisher: American Meteorological Society
Abstract: ost global circulation models and climate?chemistry models forced with increasing greenhouse gases predict a strengthening of the Brewer?Dobson circulation (BDC) in the twenty-first century, and some of them claim that ...
