Goddard Latent Heating Retrieval Algorithm for TRMM and GPM

Retrieval of Latent Heating from Trmm Measurements

P recipitation, in driving the global hydrological cycle, strongly influences the behavior of the Earth’s weather and climate systems and is central to their variability. Two-thirds of the global rainfall occurs over the Tropics,1 which leads to its profound effect on the general circulation of the atmosphere. This is because its energetic equivalent, latent heating (LH), is the tropical convec...

The Fourth Trmm Latent Heating Workshop

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 of the total heat energy available to Earth’...

Systems Engineering Analysis of a Trmm - like Retrieval Algorithm : Implication for Gpm Design

Satellite systems such as the Tropical Rainfall Measuring Mission (TRMM) are complex and rely on the proper design and functioning of each of its many subsystems—satellite vehicle, ground validation (GV) sites, precipitation radar (PR), calibration, and retrieval algorithms—to ensure high quality data products. The retrieval algorithms employed in TRMM are based on mathematical models and assum...

TRMM Latent Heating Retrieval: Applications and Comparisons with Field Campaigns and Large-Scale Analyses

Yanai and coauthors utilized the meteorological data collected from a sounding network to present a pioneering work in 1973 on thermodynamic budgets, which are referred to as the apparent heat source (Q1) and apparent moisture sink (Q2). Latent heating (LH) is one of the most dominant terms in Q1. Yanai’s paper motivated the development of satellite-based LH algorithms and provided a theoretica...
