Abstract : The AFGWC objective three-dimensional nephanalysis program (3DNEPH) produces high resolution, three-dimensional analyses of clouds in the atmosphere. A horizontal grid spacing of approximately 25 nautical miles is used. Analyses are made for 15 layers from the earth's surface to 40,000 feet MSL, with higher vertical resolution near the surface (150 feet depth for layer 1) and lower vertical resolution at the top of the model (5000 feet depth for layer 15). The program is a stream of individual processors. The active processors are: surface data processor, radiosonde data processor, aircraft data processor, satellite video data processor, decision tree processor, final processor and the special display processor. A description of each processor is given, along with some of the major decisions made within each processor. (Author)
