Download 5x4 Atmosphere-Ocean Model Code and Input Files

From this web page, you can download the Fortran source code and input files of the 1999 version of the Atmosphere-Ocean Model which runs on UNIX workstations. Running the Model requires a significant investment in time and money; it is not appropriate for students. We are happy to answer questions from permanent scientific institutions that plan to use or are using the Atmosphere-Ocean Model.

The three "tar" files listed here contain all of the individual files listed on this page:
CODE.tar Tar file containing instructions, Kornshell scripts, and Fortran source code for the Model.
INPUT.tar Tar file containing Model input files.
DIAG.tar Tar file containing Fortran source programs that read the Model's D (unscaled diagnostic) files and produce scaled DataFiles, scaled LinePlotFiles, and scaled printer files.

If you have downloaded any of the tar files to your local UNIX workstation disk, at the UNIX prompt execute: tar xvf CODE.tar or tar xvf INPUT.tar or tar xvf DIAG.tar . The component files are expanded inside the current UNIX directory.

Fortran source code files that have a ".S" extent use the first eight characters of each line as a line number as mentioned in the file EXECUTE. Three of the input files (14, 17 and 54) are ASCII files. Most of the other input files are DataFiles which means that they can be operated on by QDF, MEAN, DATA, CPSIJ and other programs.


Scripts for Compiling and Running the Atmosphere-Ocean Model
EXECUTE Instructions for executing Atmosphere-Ocean Model on a UNIX workstation
FCE Kornshell script to compile Fortran-90 source file (including .S files) into executable module
FCO Kornshell script to compile Fortran-90 source file (including .S files) into object module using "-static" option
