Abstract The package contains documentation of the Flexible Regional Emissions Data System (FREDS) for the 1980 NAPAP Emissions Inventory, FREDS source code, allocation factor files, and peripheral data files. FREDS extracts emissions data, pertinent modeling parameters (e.g., stack height, exhaust gas temperature, etc.) and source identification information from Emissions Inventory System (EIS) Master File records or preprocessed Statistical Analysis System (SAS) files and applies appropriate temporal, spatial, and pollutant species allocation factors to derive a gridded, speciated, and temporally resolved emissions file suitable as input to regional scale atmospheric simulation models (such as the Regional Acid Deposition and Regional Oxidant Models). FREDS consists of five main modules which are used to apply allocation factors to the annual emissions data, plus peripheral software used to ensure the quality of and maintain the allocation factor files. Separate programs are used to process point and area sources. Each module requires a user defined control options file. The five primary modules are the Model Data Extraction Module (MDEM), the Temporal Allocation Module (TAM), the Speciation Module (SM), the Spatial Allocation Module (SAM), and the Model Input Preprocessor (MIP). To maximize flexibility, FREDS allows the user to define and assign emissions of up to 15 pollutants (referenced by SAROAD code), the temporal scenario, spatial grid origin and grid cell size, and the number and relationship of pollutant subspecies. FREDS' modules are written in the language of the Statistical Analysis System...Software Description: The model is written in the SAS programming language for implementation on a IBM 3090 Computer using the OS/TSO operating system. Memory requirement is 1536 K bytes.
Availability Notes Source tape is in the EBCDIC character set. This restricts preparation to 9 track, one-half inch tape only. Identify recording mode by specifying density only. Call NTIS Computer Products if you have questions. Price includes documentation, PB88-129499.
