We would like to thank Mr. J. Kim of the Florida State University for programming support and Dr. N. Grody at NOAA/NESDIS, Camp Springs, MD, for useful discussions on the physical interpretation of SSM/I measurements. Longwave radiation data used in the study were obtained from NASA/Langley Research Center Distributed Active Archive Center. The NDVI data were obtained from Dr. C. J. Tucker of NASA Goddard Space Flight Center, Greenbelt, Maryland. This work was sponsored by the NASA TRMM project under NASA Grant NAG5-1587. Florida State University provided some support for the participation of S. Nicholson. Dr. Frouin was supported by NASA under Grant NAGW-2727 and by the California Space Institute.
