RISOn the Possible Use of Copolar Correlation Coefficient for Improving the Drop Size Distribution Estimates at C Band
Publisher: American Meteorological Society
Abstract: A decrease in copolar correlation coefficient (?co) at C band has been observed for several rain events with broad drop size distributions (DSDs). Observational evidence comes from simultaneous measurements with a C-band ...
Shipborne Polarimetric Weather Radar: Impact of Ship Movement on Polarimetric Variables at C Band
Publisher: American Meteorological Society
Abstract: he effect of ship motion on shipborne polarimetric radar measurements is considered at C band. Calculations are carried out by (i) varying the ?effective? mean canting angle and (ii) separately examining the elevation ...
Orientation Angle Distributions of Drops after an 80-m Fall Using a 2D Video Disdrometer
Publisher: American Meteorological Society
Abstract: This note reports on the use of a 2D video disdrometer to estimate the orientation of drops (>2 mm) that were generated artificially and allowed to fall 80 m from a bridge with no obstruction and under calm conditions. ...
CPOL Radar-Derived Drop Size Distribution Statistics of Stratiform and Convective Rain for Two Regimes in Darwin, Australia
Publisher: American Meteorological Society
Abstract: This note builds on prior technique development related to the classification of rain types utilizing C-band polarimetric (CPOL) radar measurements. While the prior work was preliminary and limited in scope, the authors ...
Estimation of Spatial Correlation of Drop Size Distribution Parameters and Rain Rate Using NASA’s S-Band Polarimetric Radar and 2D Video Disdrometer Network: Two Case Studies from MC3E
Publisher: American Meteorological Society
Abstract: olarimetric radar data obtained at high spatial and temporal resolutions offer a distinct advantage in estimating the spatial correlation function of drop size distribution (DSD) parameters and rain rate compared with a ...
Effects of Incorporating a Brightband Model in a Downward-Looking Radar Rainfall Retrieval Algorithm
Publisher: American Meteorological Society
Abstract: A range-profiling method proposed for nadir-looking rain radar has been investigated using aircraft measurements of a typhoon event at 10 and 35 GHz. In order to take into account the effects of change in the hydrometeor ...
Rainfall Estimation with an Operational Polarimetric C-Band Radar in the United Kingdom: Comparison with a Gauge Network and Error Analysis
Publisher: American Meteorological Society
Abstract: he estimate of rainfall using data from an operational dual-polarized C-band radar in convective storms in southeast United Kingdom is compared against a network of gauges. Four different rainfall estimators are considered: ...
Do We Observe Aerosol Impacts on DSDs in Strongly Forced Tropical Thunderstorms?
Publisher: American Meteorological Society
Abstract: ain drop size distributions retrieved from polarimetric radar measurements over regularly occurring thunderstorms over the islands north of Darwin, Australia, are used to test if aerosol contributions to the probability ...
A Robust C-Band Hydrometeor Identification Algorithm and Application to a Long-Term Polarimetric Radar Dataset
Publisher: American Meteorological Society
Abstract: new 10-category, polarimetric-based hydrometeor identification algorithm (HID) for C band is developed from theoretical scattering simulations including wet snow, hail, and big drops/melting hail. The HID is applied to ...
Drop Shapes and Fall Speeds in Rain: Two Contrasting Examples
Publisher: American Meteorological Society
Abstract: wo rain events are analyzed using two collocated 2D-video disdrometers (2DVD) and a C-band polarimetric radar at 15-km distance. Both events had moderate-to-intense rainfall rates, but the second event had an embedded ...
