The Dual-frequency Precipitation Radar (DPR) installed on the Global Precipitation Measurement (GPM) core satellite is being developed by JAXA and NICT. This paper describes the mission objectives, the precipitation measurement method and techniques, and the construction of the DPR. Keywords-GPM; DPR; precpitation measurement

The Global Precipitation Mission (GPM) Core Observatory that was launched on 27 February 2014 ushered in a new era for estimating precipitation from satellites. Based on their high spatial–temporal resolution and near global coverage, satellite-based precipitation products have been applied in many research fields. The goal of this study was to quantitatively compare two of the latest GPM-era s...

This study uses Dynamics of theMadden–Julian Oscillation (DYNAMO) shipborne [Research Vessel (R/V) Roger Revelle] radar and Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) datasets to investigate MJO-associated convective systems in specific organizational modes [mesoscale convective system (MCS) versus sub-MCS and linear versus nonlinear]. TheRevelle radar sampledmany ‘‘cli...

In early February 2000, primary-to-secondary tube leakage ranging from one to four gallons per day (gpd) was detected in steam generator (SG) No. 24. On February 15, 2000, while the unit was operating at 99% power, SG leakage rapidly increased from 4 gpd to greater than 75 gallons per minute (gpm). The reactor was manually tripped 13 minutes later, and the faulted steam generator was isolated o...

This study evaluates the capacity of three gridded precipitation products (MSWEP V2.2, TRMM-3B42 V7, and GPM-IMERG V6) to detect in Min Jiang watershed, a data-scarce mountainous region western China. A set statistical contingency indices is calculated for compared with rain gauge observations at 23 ground stations from July 2000 May 2016. Consistency between datasets examined different tempora...

The hydrolyzing activities in rat small intestine for newly developed sugar substitutes, ƒ¿-D-glucopyranosyl-1,6-sorbitol (GPS) and a D-glucopyranosyl-1,6-mannitol (GPM), both of which are produced by hydrogenation of palatinose, were characterized. GPS and GPM were hydrolyzed in mucosal homogenate as well as in brush border membranes of rat small intestine at a slower rate than the rate of hyd...

In this paper we present an improved search procedure for the General Parameter Method (GPM) 1]. Our procedure maps uniform dependence algorithms to application-specic processor arrays (PAs). It can optimize general design objectives with certain non-monotonicity properties, i.e., those that do not increase monotonically with the parameters. An example of such an objective is the minimization o...

Abstruct-The Tropical Rain Measuring Mission (TRMM) precipitation radar (PR) is designed to measure backscatter from rain in order to map the ;mount and extent of rain in the tropical regions. The TRMM F'R also measures the normalized radar cross section (a") of the surface at a nominal resolution of approximately 4.4 km over an incidence range of 018". The Kuband NASA Scatterometer (NSCAT) mad...
