Abstract :
A database of cloud genera is illustrated in terms of statistical distributions of hydrometeor vertical profiles. Since it is mainly derived from a microphysical model, it keeps both the microphysical consistency and the meteorological meaning. A simulated database of brightness temperatures, observed both from a spaceborne radiometer as the Special Sensor Microwave Imager and from a ground-based radiometer, is produced. An automatic classifier of cloud genera is proposed and its performances analyzed. Comparisons among SSM/I data, ground-based measurements and meteorological information are also described
