Abstract : This report presents an assortment of useful vertical cloud layer intensities received by a 35-GHz radar. Both monthly and seasonal (summer and winter) vertical cloud layer statistics are presented showing: (1) probabilities of clouds aloft, (2) diurnal cloud layer analysis, (3) probabilities of vertical cloud-free-line-of-site between two heights, (4) cloud layer correlation's between two heights; and seasonal statistics for, (5) serial correlation's of clouds at specified altitudes, (6) probabilities of vertical cloud thicknesses, (7) probabilities of cloudy or clear run lengths, and (8) a method for converting cloudy or clear mn length probabilities to persistence probabilities. Data collection and cloud extraction methods are explained and methods usd for deriving the statistics are documented. (AN)
