We are very grateful for continuing support from the National Aeronautics and Space Administration (NASA). We are thankful to the Defense Meteorological Satellite Program for making the SSM/I data available to the civilian community. We have been supported by NASA NEWS under Contract NNG05OAR4311111 and by DISCOVER, which is supported by the NASA Earth Science Research, Education, and Applications Solution Network (REASoN) Project under Cooperative Agreement NNG04GG46A. REASoN is a distributed network of data and information providers for NASA’s Earth Science Enterprise (ESE) Science, Applications, and Education programs. REASoN provides vital links between NASA’s data, modeling, and systems engineering capabilities and the user communities in research, applications, and education. The AMSR-E work was partially supported by NASA Contract NNG04HZ47C. We are grateful to three anonymous reviewers whose comments have greatly enhanced the clarity of this paper.
The GPCP combined precipitation data were developed and computed by the NASA Goddard Space Flight Center’s Laboratory for Atmospheres as a contribution to the GEWEX Global Precipitation Climatology Project. GPROF TMI data used in this study were acquired as part of the Tropical Rainfall Measuring Mission (TRMM). The algorithms were developed by the TRMM Science Team. The data were processed by the TRMM Science Data and Information System (TSDIS) and the TRMM Office; they are archived and distributed by the Goddard Distributed Active Archive Center. TRMM is an international project jointly sponsored by the Japan National Space Development Agency (NASDA) and the U.S. NASA Office of Earth Sciences.
