Analisi e sviluppo di modelli per l’individuazione di nubi per la simulazione della temperatura di brillanza

Two cloud water models that can be included in the radiative transfer to simulate brightness temperatures from radiosonde data are analyzed. The capability of the models to detect the presence of clouds was evaluated and optimized by comparing the cloud base heights identified from the radiosoundings with those provided by a ceilometer. Then, the performances of the different cloud models are analyzed by comparing simulated brightness temperatures in the absence of scattering with those measured by a dual-channel microwave radiometer.
