Selected analyses of TRMM instantaneous rainfall data

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Distributions of Tropical Rainfall Measuring Mission (TRMM) Version 5 (V5) and Version 6 (V6) data are presented. The fraction of pixels determined by the Precipitation Radar (PR) to be convective has increased by 5% from V5 to V6. In V6, PR contributes more rain in medium ( 4 to 20 mm/hr) but less in heavy ( >20 mm/hr) rainfall rates than the TRMM ...

TRMM Active/Passive Ocean Vector Wind Retrievals

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
This paper presents a novel ocean vector wind (OVW) retrieval algorithm that uses the Precipitation Radar (PR) and the TRMM Microwave Imager (TMI) on board of the Tropical Rainfall Measuring Mission (TRMM) satellite. In this paper, the modified 2nd Stokes parameter (weighted difference of V & H-pol Tb’s) is used to cancel the atmosphere, which enhances

TRMM rainfall algorithm development

Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002
This paper categorizes the algorithms which are being developed for the Tropical Rainfall Measuring Mission (TRMM). The discussion includes algorithms which utilize the active and passive microwave sensors as well as the combination of all rain sensors on TRMM and beyond to an algorithm which considers the TRMM satellite in conjunction with other ...

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/.

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

CERES/TRMM mission: early results

SPIE Proceedings, 1998
The first CERES instrument has been placed in orbit on the TRMM Spacecraft. This instrument is designed to measure the Earth's radiation budget and also the anisotropy of reflected solar radiation and outgoing longwave radiation. The TRMM orbit and the combination of CERES with other instruments aboard the spacecraft provide a unique opportunity for a ...

Estimates of path attenuation for the TRMM radar

IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998
It is well known that radar signals above 10 GHz can suffer significant attenuation in rain even over the relatively short rain paths associated with near-nadir viewing angles. Also well known is the problem of instabilities in estimating the radar reflectivity factor, Z, from measurements at a single attenuating wavelength radar.

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.
