LACC 99-18

Abstract:

The LANL version of this manaual, which contains detailed instructions for operating the stand-alone version of POP, is the basis of the CCSM4 version, which you are now reading. The CSM4 version of the manual has been customized to include information about CCSM4-specific POP options. Throughout this document, CCSM4- and LANL-specific sections are identified as such.

Topics include:

Throughout this manual, it is assumed that the operating system is some variant of Unix. However, POP has been run on PCs under windows.

To keep the User's Guide as short as possible, LANL developers intend to create a Reference Manual for those users who seek an in-depth understanding of the code, such as would be needed to make changes to the source code. It contains a thorough description of the code, including the model equations, their discretized form, and the numerical methods used for their solution. The principal modules and subroutines are explained, the organization of the code is outlined, and the principal variables are defined.

Whenever POP is run, the version number and release date of the source code on your local system is output at the beginning of the log file. They should agree with the information on the front cover of this manual. If they do not, you can obtain the current version of the LANL POP2 manual at http://climate.lanl.gov/Models/POP/.

The Manual revision letter and release date indicate corrections or additions to the manual corresponding to the stated version of the model.

If you obtained POP directly from LANL, technical support is provided by John Davis ( jfd@lanl.gov, 505-667-4793) and Phil Jones (pwjones@lanl.gov , 505-667-6386). We are always interested in learning about your experiences with POP, favorable or otherwise. Send your comments and suggestions for improvements to pop_feedback@acl.lanl.gov. Bug reports should be sent to pop_bugs@acl.lanl.gov.

If you are using POP as a component of the NCAR Climate System Model (CCSM4), technical support is provided by NCAR. Follow the instructions in the Reporting a Problem section of the CCSM4.0 main website.
