This project was supported by the National Science Foundation (ATM-9413453), by the National Group for Defense from Hydrological Hazards (CNR, Italy), by Progetto Strategico Mesoscale Alpine Program (CNR, Italy), by the Italian Space Agency (ASI), and by the NASA TRMM program. The CSU–CHILL is supported by the National Science Foundation (ATM-9500108). The gauge data were collected and archived by the Colorado Climate Center, and the radar data were collected by Bob Bowie of the CSU–CHILL facility. The authors are grateful to A. Mura and P. Iacovelli for assistance rendered during the preparation of the manuscript.
