Validation of TRMM Precipitation Radar through Comparison of its Multi-Year Measurements to Ground-Based Radar
A procedure to accurately resample spaceborne and ground-based radar data is described, and then applied to the measurements taken from the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) and the ground-based Weather Surveillance Radar-1988 Doppler (WSR-88D or WSR) for the validation of the PR measurements and estimates. Through comparisons with the well-calibrated, non-atte...

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...
متن کاملValidation of rainfall estimates from the TRMM precipitation radar and microwave imager using a radiative transfer model: 1. Comparison of the version-5 and -6 products
[1] The Tropical Rainfall Measuring Mission (TRMM) version-6 rainfall products show the reduced bias between Precipitation Radar (PR) and TRMM Microwave Imager (TMI) rainfall estimates during the 1997/1998 El Niño event noted in version 5, but need to be verified. We investigate consistency between TMI-observed brightness temperatures (TBs) at 10 and 19 GHz channels and those simulated from the...
متن کاملComparison of Rainfall Products Derived from TRMM Microwave Imager and Precipitation Radar
Satellite remote sensing is an indispensable means of measuring and monitoring precipitation on a global scale. The Tropical Rainfall Measuring Mission (TRMM) is continuing to make significant progress in helping the global features of precipitation to be understood, particularly with the help of a pair of spaceborne microwave sensors, the TRMM Microwave Imager (TMI) and precipitation radar (PR...
متن کاملTrmm Precipitation Radar Version 6 Algorithms
Following the first (1991-1993) and the second (1994-1996) TRMM PR teams, and the third international TRMM PR team (1997-2000), the fourth international TRMM PR team (2001-2003) started its job in 2001 based on the NRA-99-OES-03 in 1999 and NASDA-3rd RA-TRMM in 2000. In April 2004, the fourth international TRMM PR team completed the revisions of the standard algorithms to version 6. NASA and JA...
