Spectral Polarimetric Radar Clutter Suppression to Enhance Atmospheric Echoes
Publisher: American Meteorological Society
Abstract: The clutter present in the Doppler spectra of atmospheric targets can be removed by using polarimetry. The purpose is to suppress the Doppler velocity bins where spectral polarimetric parameters have atypical values. This ...
High-Resolution Raindrop Size Distribution Retrieval Based on the Doppler Spectrum in the Case of Slant Profiling Radar
Publisher: American Meteorological Society
Abstract: oppler spectra from vertically profiling radars are usually considered to retrieve the raindrop size distribution (DSD). However, to exploit both fall velocity spectrum and polarimetric measurements, Doppler spectra acquired ...
Adaptive and High-Resolution Estimation of Specific Differential Phase for Polarimetric X-Band Weather Radars
Publisher: American Meteorological Society
Abstract: ABSTRACTOne of the most beneficial polarimetric variables may be the specific differential phase KDP because of its independence from power attenuation and radar miscalibration. However, conventional KDP estimation requires ...
A Critical Evaluation of the Adequacy of the Gamma Model for Representing Raindrop Size Distributions
Publisher: American Meteorological Society
Abstract: The adequacy of the gamma model to describe the variability of raindrop size distributions (DSD) is studied using observations from an optical disdrometer. Model adequacy is checked using a combination of Kolmogorov–Smirnov ...
Improved Polarimetric Calibration for Atmospheric Radars
Publisher: American Meteorological Society
Abstract: Polarization properties of radar waves that are scattered from atmospheric objects are of great interest in meteorological studies. However, polarimetric radar measurements are often not sufficiently accurate for retrieving ...
Retrieving Fall Streaks within Cloud Systems Using Doppler Radar
Publisher: American Meteorological Society
Abstract: he interaction of ice crystals with supercooled liquid droplets in mixed-phase clouds leads to an enhanced growth of ice particles. However, such processes are still not clearly understood although they are important ...
