RISEstimation 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 ...
Diurnal Characteristics of Precipitation Features over the Tropical East Pacific: A Comparison of the EPIC and TEPPS Regions
Publisher: American Meteorological Society
Abstract: This study examines the diurnal cycle of precipitation features in two regions of the tropical east Pacific where field campaigns [the East Pacific Investigation of Climate Processes in the Coupled Ocean?Atmosphere System ...
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 ...
Radar Characteristics of Precipitation Features in the EPIC and TEPPS Regions of the East Pacific
Publisher: American Meteorological Society
Abstract: Ship-based radar data are used to compare the structure of precipitation features in two regions of the east Pacific where recent field campaigns were conducted: the East Pacific Investigation of Climate Processes in the ...
A Methodology to Derive Radar Reflectivity–Liquid Equivalent Snow Rate Relations Using C-Band Radar and a 2D Video Disdrometer
Publisher: American Meteorological Society
Abstract: The objective of this work is to derive equivalent radar reflectivity factor?liquid equivalent snow rate (Ze?SR) power-law relations for snowfall using the C-band King City operational weather radar and a 2D video disdrometer ...
Estimating the Accuracy of Polarimetric Radar–Based Retrievals of Drop-Size Distribution Parameters and Rain Rate: An Application of Error Variance Separation Using Radar-Derived Spatial Correlations
Publisher: American Meteorological Society
Abstract: he accuracy of retrieving the two drop size distribution (DSD) parameters, median volume diameter (D0), and normalized intercept parameter (NW), as well as rain rate (R), from polarimetric C-band radar data obtained during ...
Potential Role Of Dual- Polarization Radar In The Validation Of Satellite Precipitation Measurements: Rationale and Opportunities
Publisher: American Meteorological Society
Abstract: Dual-polarization weather radars have evolved significantly in the last three decades culminating in operational deployment by the National Weather Service. In addition to operational applications in the weather service, ...
North Alabama Lightning Mapping Array (LMA): VHF Source Retrieval Algorithm and Error Analyses
Publisher: American Meteorological Society
Abstract: Two approaches are used to characterize how accurately the north Alabama Lightning Mapping Array (LMA) is able to locate lightning VHF sources in space and time. The first method uses a Monte Carlo computer simulation to ...
