This work is dedicated to Dr. James Hollinger, leader of the navy’s SSM/I Cal/Val program. The authors wish to thank all of the members of the SSM/I Cal/Val team for their contributions to the development of the algorithm, especially Mark Goodberlet for his help with SSM/I data geolocation. David Wolff, Lynn Rose, Brian Morrison, and David Brown provided invaluable validation radar data for this study.
