This work was supported by NASA TRMM Grant NAG5-10482. The TRMM data products were provided through the TRMM Science Data and Information System. ECMWF analysis data was provided from the European Centre for Medium-Range Weather Forecasts via the National Center for Atmospheric Research, and NCEP reanalysis was obtained from NOAA's Climate Diagnostics Center. The monthly GPI and SSM/I rainfall estimates were obtained through the Global Precipitation Climatology Project courtesy of George Huffman, and SST and water vapor products from TMI were obtained from Remote Sensing Systems.
