RISRainfall Parameter Estimation from Dual-Radar Measurements Combining Reflectivity Profile and Path-integrated Attenuation
Publisher: American Meteorological Society
Abstract: Rain rate estimation properties of multiparameter radar measurements combining radar reflectivity and microwave attenuations are studied through simulations using a two-year disdrometer dataset. In the first simulation, ...
Nonuniform Beamfilling Correction for Spaceborne Radar Rainfall Measurement: Implications from TOGA COARE Radar Data Analysis
Publisher: American Meteorological Society
Abstract: A method is studied to make a nonuniform beamfilling (NUBF) correction for the path-integrated attenuation (PIA) derived from spaceborne radar measurement. The key of this method is to estimate rain-rate variability within ...
Preliminary Results from Multiparameter Airborne Rain Radar Measurement in the Western Pacific
Publisher: American Meteorological Society
Abstract: Preliminary results are presented from multiparameter airborne radar measurements of tropical storms. The experiment was conducted in the western Pacific in September 1990 with the NASA DC-8 aircraft that was equipped with ...
Raindrop Size Distribution Modeling from a Statistical Rain Parameter Relation and Its Application to the TRMM Precipitation Radar Rain Retrieval Algorithm
Publisher: American Meteorological Society
Abstract: A generalized method is presented to derive a ?two scale? raindrop size distribution (DSD) model over a spatial or temporal domain in which a statistical rain parameter relation exists. The two-scale model is generally ...
Estimation of N*0 for the Two-Scale Gamma Raindrop Size Distribution Model and Its Statistical Properties at Several Locations in Asia
Publisher: American Meteorological Society
Abstract: An automatic estimation method is developed to detect stepwise changes in the amplitude parameter of the normalized raindrop size distribution (DSD) N*0. To estimate N*0, it is also assumed that the variation of three DSD ...
The Tropical Rainfall Measuring Mission (TRMM) Sensor Package
Publisher: American Meteorological Society
Abstract: This note is intended to serve primarily as a reference guide to users wishing to make use of the Tropical Rainfall Measuring Mission data. It covers each of the three primary rainfall instruments: the passive microwave ...
Continuous Humidity Monitoring in a Tropical Region with the Equatorial Atmosphere Radar
Publisher: American Meteorological Society
Abstract: A radar remote sensing technique that estimates humidity profiles using a wind profiler is applied to the equatorial atmosphere radar (EAR) to monitor detailed humidity variations in tropical regions. Turbulence echo power ...
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 ...
Rain-Profiling Algorithm for the TRMM Precipitation Radar
Publisher: American Meteorological Society
Abstract: This paper describes the Tropical Rainfall Measuring Mission (TRMM) standard algorithm that estimates the vertical profiles of attenuation-corrected radar reflectivity factor and rainfall rate. In particular, this paper ...
The Shape–Slope Relation in Observed Gamma Raindrop Size Distributions: Statistical Error or Useful Information?
Publisher: American Meteorological Society
Abstract: The three-parameter gamma distribution n(D) = N0Dµ exp(??D) is often used to characterize a raindrop size distribution (DSD). The parameters µ and ? correspond to the shape and slope of the DSD. If µ and ? are related to ...
