CERES/TRMM mission: early results
SPIE Proceedings, 1998The 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), 1998It 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.

Evaluation of surface clutter for the design of the TRMM spaceborne radar
IEEE Transactions on Geoscience and Remote Sensing, 1992Surface clutter interference through antenna sidelobes on rainfall measurements by spaceborne rain radar is quantitatively examined in order to clarify design criteria for the antenna. The received intensities of both rain echo and sea clutter are evaluated numerically, assuming appropriate precipitation and sea surface scattering models and a ...

Evaluation of TRMM PR attenuation by radar mirror image
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 20042 Code 975, NASA/GSFC, Greenbelt, MD 20771 Abstract- The Mirror Image (MI) rain return, an echo below the ocean surface observed by the TRMM PR through the double reflection of the radar pulse from the surface, is used for the estimation of rain path attenuation. Two MI algorithms are discussed and then applied to the PR measurements over the ocean for

Evolution of the rain profiling algorithm for the TRMM Precipitation Radar
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011In the Tropical Rainfall Measuring Mission (TRMM), the standard algorithm that estimates the instantaneous rain profiles from the Precipitation Radar (PR) data has been revised several times since its launch in 1997. This paper describes the major changes in different versions of the algorithm and the reasons for the revisions.

TRMM: The Tropical Rainfall Measuring Mission
1996Precipitation is one of the most important parts of both the global water and energy cycles, yet it is one of the most poorly observed climate parameters. Globally, the net latent heating associated with precipitation accounts for about 80% of the total diabatic heating required to balance radiative cooling to space.
