Deep convection observed from split window of GOES and PR/TRMM, LIS/TRMM
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Deep convection over South America is investigated in terms of cloud type classified by the split window (11 and 12 /spl mu/m) using the hourly data of GOES, and rainfall by the PR (Precipitation Radar), and lightning activity by the LIS (Lightning Imaging Sensor) on board TRMM (Tropical Rainfall Measuring Mission) as case studies.

Selected analyses of TRMM instantaneous rainfall data
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004Distributions 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 microwave radiometer algorithms
Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002The 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/.

TRMM rainfall algorithm development
Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002This 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 ...

TRMM Active/Passive Ocean Vector Wind Retrievals
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019This 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

Precipitation radar onboard TRMM satellite
Proceedings of International Symposium on Phased Array Systems and Technology, 2002A 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, 2007In 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 ...

Remote sensing of fires with the TRMM VIRS
International Journal of Remote Sensing, 2000Although 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, 2017AbstractThis 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 ...

Development results of the precipitation radar on TRMM
SPIE Proceedings, 1997Precipitation 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
