Abstract The Valley Model Computer Program is an analytical technique whose primary use is for estimating the upper limits of 24-hour average pollutant concentrations due to isolated sources in rural, complex terrain...Software Description: The simulation model is written in the Fortran programming language for implementation on a UNIVAC 1110 computer using the EXEC 8 operating system. 56K 36-bit words of core storage is required to operate the model. The User's Manual, Valley Model User's Guide, is also available separately from NTIS as PB-274 054, at $6.50 per copy.
Availability Notes Source tape is in EBCDIC character set. Tape(s) can be prepared in most standard 7 or 9 track recording modes for one-half inch tape. Identify recording mode desired by specifying character set, track, density, and parity. Call NTIS Computer Products if you have questions. Price includes documentation, PB-274 054. Also available as punched cards.
