RISEvaluation of TRMM Ground-Validation Radar-Rain Errors Using Rain Gauge Measurements
Publisher: American Meteorological Society
Abstract: Ground-validation (GV) radar-rain products are often utilized for validation of the Tropical Rainfall Measuring Mission (TRMM) space-based rain estimates, and, hence, quantitative evaluation of the GV radar-rain product ...
Evaluation of TRMM Rain Estimates Using Ground Measurements over Central Florida
Publisher: American Meteorological Society
Abstract: This study evaluates space-based rain estimates from the Tropical Rainfall Measuring Mission (TRMM) satellite using ground-based measurements from the radar (GR) and tipping-bucket rain gauges (TG) over the TRMM Ground ...
Comparisons of Reflectivities from the TRMM Precipitation Radar and Ground-Based Radars
Publisher: American Meteorological Society
Abstract: Given the decade-long and highly successful Tropical Rainfall Measuring Mission (TRMM), it is now possible to provide quantitative comparisons between ground-based radars (GRs) and the spaceborne TRMM precipitation radar ...
Satellite Sampling and Retrieval Errors in Regional Monthly Rain Estimates from TMI, AMSR-E, SSM/I, AMSU-B, and the TRMM PR
Publisher: American Meteorological Society
Abstract: assive and active microwave rain sensors on board Earth-orbiting satellites estimate monthly rainfall from the instantaneous rain statistics collected during satellite overpasses. It is well known that climate-scale rain ...
Assessing the Relative Performance of Microwave-Based Satellite Rain-Rate Retrievals Using TRMM Ground Validation Data
Publisher: American Meteorological Society
Abstract: Spaceborne microwave sensors provide critical rain information used in several global multisatellite rain products, which in turn are used for a variety of important studies, including landslide forecasting, flash flood ...
Comparisons of Instantaneous TRMM Ground Validation and Satellite Rain-Rate Estimates at Different Spatial Scales
Publisher: American Meteorological Society
Abstract: This study provides a comprehensive intercomparison of instantaneous rain rates observed by the two rain sensors aboard the Tropical Rainfall Measuring Mission (TRMM) satellite with ground data from two regional sites ...
C-Band Attenuation by Tropical Rainfall in Darwin, Australia, Using Climatologically Tuned Ze-R Relations
Publisher: American Meteorological Society
Abstract: The probability matching method (PMM) is used as a basis for estimating attenuation in tropical rains near Darwin, Australia. PMM provides a climatological relationship between measured radar reflectivity and rain rate, ...
General Probability-matched Relations between Radar Reflectivity and Rain Rate
Publisher: American Meteorological Society
Abstract: A method of deriving the relation between radar-observed reflectivities Ze and gauge-measured rain intensity, R is presented. It is based on matching the probabilities of the two variables. The observed reflectivity is ...
The Window Probability Matching Method for Rainfall Measurements with Radar
Publisher: American Meteorological Society
Abstract: A simplified probability matching method is introduced that relies on matching the unconditional probabilities of R and Ze, using data from a C-band radar and raingage network near Darwin, Australia. This is achieved by ...
Classification of Rain Regimes by the Three-Dimensional Properties of Reflectivity Fields
Publisher: American Meteorological Society
Abstract: An automated scheme to characterize precipitation echoes within small windows in the radar field is presented and applied to previously subjectively classified tropical rain cloud systirns near Darwin, Australia. The ...
