Generation of CCM Format History Tapes from Analyzed Data for Selected Periods (RD2CFM Version 01)

摘要

The CCM model and the modular processor require that input data be in CCM history tape form. The purpose of the software described herein is to generate such history tapes from various analyses of observed data, add climatological lower boundary data where necessary, and output the data in a Type 1 or Type 2 CCM history tape format at an arbitrary resolution on either pressure or sigma surfaces. History tapes with data on sigma surfaces may be used by either the model or the processor while history tapes with data on pressure surfaces may be used by the processor only. There are three common uses for these history tapes. They may be used to start the model. They may be used as a data source against which model forecasts may be verified in the processor. Finally, in conjunction with the processor, they may be used to perform data analysis of one of the analyzed data sources without using the model at all.
