ACTS propagation experiment: rain-rate distribution observations and prediction model comparisons

Empirical distribution functions for one-minute average rain-rate values were compiled for nine station years of observations at five of the Advanced Communications Technology Satellite (ACTS) propagation experiment terminal sites. The empirical distribution functions were compared with cumulative distribution functions generated by three different rain-rate distribution prediction models. On the basis of the expected differences between model predictions and experimental measurements, not one of the model combinations provided good predictions.
