The authors extend their heartfelt appreciation to the late Professor Michio Yanai of the University of California at Los Angeles. The enthusiasm of Dr. Yanai over the years and his willingness to discuss ideas concerning the subject of atmospheric latent heating and its implications with the various authors has had a profound influence on ideas central to this paper. We also appreciate the leadership of the late Dr. Joanne Simpson, a close colleague of Dr. Yanai and the first TRMM project scientist in the United States, and the late Prof. Tsuyoshi Nitta, who was a student of Dr. Yanai and the TRMM project scientist in Japan. Drs. Simpson, Robert Adler, Robert Houze, and Nitta promoted LH as being one of the two key products for TRMM. The authors also thank two anonymous reviewers for their constructive comments that improved this paper considerably.
Acknowledgment is also made to the NASA Center for Climate Simulation (NCCS) at the NASA Goddard Space Flight Center for computer time used in this research. Finally, the authors appreciate the implementation of LH retrieval algorithms into the Precipitation Processing System also at the NASA Goddard Space Flight Center and the TRMM Mission Operation System at the Japan Aerospace Exploration Agency (JAXA) for the production of standardized LH products. This research has been supported by an assortment of PMM Science Team grants under the auspices of both the National Aeronautics and Space Administration (NASA) and the Japan Aerospace Exploration Agency (JAXA). D. Waliser’s contribution was carried out on behalf of the Jet Propulsion Laboratory, California Institute of Technology, under a contract with NASA. X. Jiang was also supported by the NSF Climate and Large-Scale Dynamics Program under Awards ATM-0934285 and AGS-1228302.
