Precipitation radar onboard TRMM satellite

Proceedings of International Symposium on Phased Array Systems and Technology, 2002
A precipitation radar (PR) onboard the TRMM satellite has been developed by NASDA. The PR employs a 128-element active phased array and can measure the 3-dimensional rain distribution over the swath width of 215 km with a resolution of 4.3 km in the horizontal and 250 m in range.

The Fourth TRMM Latent Heating Workshop

Bulletin of the American Meteorological Society, 2007
In final form 30 May 2007 © 2007 American Meteorological Society he global hydrological cycle is central to Earth’s climate system, with rainfall and the physics of precipitation formation acting as the key links in the cycle. Two-thirds of global rainfall occurs in the Tropics with the associated latent heat (LH) release accounting for three-fourths ...

Development results of TRMM precipitation radar

IGARSS'97. 1997 IEEE International Geoscience and Remote Sensing Symposium Proceedings. Remote Sensing - A Scientific Vision for Sustainable Development, 2002
A precipitation radar (PR) has been developed by the National Space Development Agency of Japan (NASDA) in cooperation with the Communication Research Laboratory (CRL). The PR was integrated into the Tropical Rainfall Measuring Mission (TRMM) satellite and TRMM satellite system testing is ongoing by NASA.

Research on Downscaling and Correction of TRMM Data in Central China

2021
The Central China has abundant rainfall, and rainfall is unevenly distributed in space and time, which can easily cause floods and soil erosion. It is of great significance to obtain precipitation information accurately and quickly. At present, remote sensing precipitation data has been widely used, but its spatial resolution and data accuracy still ...

Remote sensing of fires with the TRMM VIRS

International Journal of Remote Sensing, 2000
Although the Visible and Infrared Scanner (VIRS) instrument on board the Tropical Rainfall Measuring Mission (TRMM) satellite is designed primarily to study precipitation, it offers a new opportunity for the remote sensing of fire activity in regions within 40 of the equator.

GLD360 Performance Relative to TRMM LIS

Journal of Atmospheric and Oceanic Technology, 2017
AbstractThis study evaluates the performance of the operational and reprocessed Global Lightning Dataset 360 (GLD360) data relative to the Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS) during 2012–14. The analysis compares ground- and space-based lightning observations to better characterize the pre- and postupgrade GLD360 ...

TRMM microwave radiometer algorithms

Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002
The TRMM Microwave Imager (TMI) is a modified SSM/I. Significant modifications include: the addition of 2 channels at 10.7 GHz (H and V polarization), a shift of the 22.235 GHz V channel to 21.4 GHz H, and increasing the cone angle from 45/spl deg/ to 49/spl deg/.

Classification and quantification of TRMM radar observations

2005
A better knowledge of precipitation types and their radar reflectivity structures is important for interpretation of space-borne radar observations as well as microphysical processes for improving satellite precipitation algorithms. The differences in microphysics, or drop size distributions lead to different reflectivity rain rate relationships for ...

Development results of the precipitation radar on TRMM

SPIE Proceedings, 1997
Precipitation Radar (PR) is a key instrument on the Tropical Rainfall Measuring MIssion (TRMM), which is a joint US/Japan space program. The PR is the first rain radar in space. The characteristics of the PR are high sensitivity, low side lobe level an the high speed electrical beam scanning. On- orbit calibration of the PR instrument will be performed

The tropical rainfall measuring mission (TRMM)

Advances in Space Research, 1994
The Tropical Rainfall Measuring Mission (TRMM) is a cooperative effort between National Space Development Agency (NASDA) of Japan and NASA of the USA. TRMM is designed to measure rain rates from space using a combination of high resolution radar, passive microwave radiometer and visible-infrared radiometer measurements from a spacecraft in a rapid ...
