ACTS PROPAGATION EXPERIMENT - RAIN-RATE DISTRIBUTION OBSERVATIONS ANDPREDICTION MODEL COMPARISONS

Empirical distribution functions for one-minute average rain-rate valu es were compiled for nine station years of observations at five of the Advanced Communications Technology Satellite (ACTS) propagation exper iment terminal sites. The empirical distribution functions were compar ed with cumulative distribution functions generated by three different rain-rate distribution pre diction models. On the basis of the expect ed differences between model predictions and experimental measurements , not one of the model combinations provided good predictions.
