We thank Dr. John Janowiak of Climate Prediction Center/NCEP/NWS for providing the GPI data. We acknowledge Drs. J. McCollum and R. Kuligowski for their critical reading of the manuscript, Dr. D. Rosenfeld of the Hebrew University of Jerusalem (Israel), and Dr. G. Gutman of NASA/GSFC for helpful discussions regarding the use of GOES channel 2 in deriving effective radii of cloud droplets. Fifteen-minute radar data were obtained from GHRC/MSFC, Huntsville, Alabama.
