Spaceborne Radar Sensing of Precipitation above an Ocean Surface: Polarization Contrast Study
Publisher: American Meteorological Society
Abstract: This feasibility study explores the potential benefits of polarization adjustment for spaceborne radar sensing of precipitation. More specifically, the role of the wave polarization in separating or ?distinguishing? ocean ...
The Use of Optimal Polarizations for Studying the Microphysics of Precipitation: Nonattenuating Wavelengths
Publisher: American Meteorological Society
Abstract: The objective of this work is to explore relationships between the microphysical properties of precipitation and optimal polarizations. The dependence of three optimal polarization parameters (asymmetry ratio ?, optimal ...
Use of the Surface Reference Technique for Path Attenuation Estimates from the TRMM Precipitation Radar
Publisher: American Meteorological Society
Abstract: Estimates of rain rate from the precipitation radar (PR) aboard the Tropical Rainfall Measuring Mission (TRMM) satellite require a means by which the radar signal attenuation can be corrected. One of the methods available ...
An Initial Assessment of the Surface Reference Technique Applied to Data from the Dual-Frequency Precipitation Radar (DPR) on the GPM Satellite
Publisher: American Meteorological Society
Abstract: t has long been recognized that path-integrated attenuation (PIA) can be used to improve precipitation estimates from high-frequency weather radar data. One approach that provides an estimate of this quantity from airborne ...
A Proposed Model-Based Methodology for Feature-Specific Prediction for High-Impact Weather
Publisher: American Meteorological Society
Abstract: feature-specific forecasting method for high-impact weather events that takes advantage of high-resolution numerical weather prediction models and spatial forecast verification methodology is proposed. An application of ...
Cloud assumption of Precipitation Retrieval Algorithms for the Dual-frequency Precipitation Radar
Publisher: American Meteorological Society
Abstract: An assumption related to clouds is one of uncertain factors in precipitation retrievals by the Dual-frequency Precipitation Radar (DPR) onboard the Global Precipitation Measurement (GPM) Core Observatory. While an attenuation ...
