Vertical Cloud Layer Statistics Derived from Echo Intensities Received by a 35 -GHz Radar

摘要

This report presents an assortment of useful vertical cloud layer intensitiesreceived 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 correlations between two heights and seasonal statistics for; (5) serial correlations 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).
