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...

Satellite-based precipitation monitoring at high spatial resolution is crucial for assessing the water and energy cycles at the global and regional scale. Based on the recently released 7th version of the Multi-satellite Precipitation Analysis (TMPA) product of the Tropical Rainfall Measuring Mission (TRMM), and the monthly precipitation data (3B43) are evaluated using observed monthly precipit...

Accurate rainfall estimations based on ground-based rainfall observations and satellite-based rainfall measurements are essential for hydrological and environmental modeling in the Qaidam Basin of China. We evaluated the accuracy of daily and monthly scale Tropical Rainfall Measuring Mission (TRMM) rainfall products in the Qaidam Basin. A Geographically Weighted Regression (GWR) was used to est...

As the successor of the Tropical Rainfall Measuring Mission (TRMM), the Global Precipitation Measurement (GPM) mission significantly improves the spatial resolution of precipitation estimates from 0.25 ̋ to 0.1 ̋. The present study analyzed the error structures of Integrated Multisatellite Retrievals for GPM (IMERG) monthly precipitation products over Mainland China from March 2014 to February 20...

Precipitation maxima during the West African summer monsoon propagate generally westward in tandem with African easterly waves. A heretofore unreported, repeating pattern of northward drift of precipitation maxima is detected on Tropical Rainfall Measurement Mission (TRMM satellite) time-latitude distributions of daily accumulations over the eastern tropical Atlantic. Corresponding 3-hourly TRM...

Accurate precipitation data at a high spatial resolution are essential for hydrological, meteorological, and ecological research at regional scales. This study presented a geostatistical downscaling-calibration procedure to derive the high spatial resolution maps of precipitation over a mountainous watershed affected by a monsoon climate. Based on the relationships between precipitation and oth...

The version 6 TRMM rainfall products showed significant improvements on satellite rain retrievals as compared to rain gauge observations. The differences between TRMM TMI rain products and gauge observations are less than 10% over Florida, Texas, Kwajalein, and Darwin ground validation sites for the 8-year period from January 1998 to December 2005. The rain differences between Version 6 TMI and...

あらまし 熱帯降雨観測衛星(TRMM:Tropical Rainfall Measuring Mission)は,1997年 11月 28日に打 ち上げられて以来,現在に至るまで,約 10 年以上も順調に,熱帯・亜熱帯降雨の観測を継続している.TRMM は,世界で初めてのアクティブフェイズドアレー方式の降雨レーダ(PR)を搭載しており,台風などをはじめ とする様々な降雨システムの三次元構造の観測にその威力を発揮してきた.論文では,TRMM 衛星のミッショ ンの目的,搭載センサの概要,TRMM降雨レーダシステムの概念設計時の諸検討,TRMM降雨レーダシステ ムの概要,TRMM降雨レーダデータ解析処理アルゴリズムシステム,様々な観測成果(台風,潜熱加熱など), TRMMを継承する全球降水観測計画(GPM:Global Precipitation Measurement)主衛星搭載 2周波...

In this study, nine-years (1998-2006) of monthly precipitation data from Tropical Rainfall Measuring Mission (TRMM) are used to examine the relations between tropical rainfall and surface temperature. A technique is developed to adjust the PR monthly rainfall data in the Tropics (whole ocean and whole land) to account for the effect of the TRMM orbit boost from 350 km to 402 km in August 2001. ...

[1] By incorporating the Tropical Rainfall Measurement Mission (TRMM) satellite orbital information into the Colorado State University General Circulation Model (CSUGCM), we are able to ‘‘fly’’ a satellite in theGCMand sample the simulated atmosphere in the sameway as the TRMM sensors sample the real atmosphere. The TRMM-sampled statistics for precipitation and radiative fluxes at annual, intra...
