Cloud Model Database Comparison Study

Abstract

This report documents the results of a study that examined and compared the Air Force Global Weather Central's (AFGWC's) climatological cloud model databases: the Real-Time Nephanalysis (RTNEPH) and the Three-Dimensional Nephanalysis (3DNEPH). The study investigates their characteristics, determines the length of a climatologically sound period of record (POR), finds a year with typical cloud cover for use as a baseline in future studies, and weighs the advantages and disadvantages of Multipurpose Simulator (MRS) databases derived from the RTNEPH and 3DNEPH. The older 3DNEPH cloud model, first used in the 1970's, produced worldwide, lavered cloud analyses on a 25-NM grid. RTNEPH replaced 3DNEPH at the beginning of 1984.
