Overview

This experiment does not require additional data. So, the experiment is performed with the following 3 steps:

Preparation of a directory for experiments

Move to "practice" directory.

$ cd practice

In the directory, execute 'make' command. The execution files and the NAMELIST files will be automatically copied. Input directory name after inputting 'make' command. (It is assumed "Venuslike-exp" in the following example). Input 'Enter' to the question after that.

$ make

****** Setup a directory for a experiment ******

  Enter directory name [testXX]: Venuslike-exp
  Directory in which executable files are prepared
    [../src/main]:
  Directory in which NAMELIST files are prepared
    [../src/main]:
  Save F90/95 source code files? [y/N]: 

                :

*** Setup of "Venuslike-exp" is complete ***

Then a directory 'Venuslike-exp' is created, and executable files, NAMELIST files, and source code files are copied to the directory. Move the 'Venuslike-exp'.

$ cd Venuslike-exp

Note that you can perform an experiment in any directory by using executable files and configuration (namelist) files.

Create initial data file

Create initial data file "init_T10L50.nc" using "init_data" and "init_data_Vlp_T10L50.nml"

$ ./init_data -N=init_data_Vlp_T10L50.nml

Run the experiment

Using an executable files 'dcpam_main' and a NAMELIST file dcpam_Vlp_T10L50.nml, execute 'dcpam_main' as follows. This program will be finished in few minutes - tens of minutes.

$ ./dcpam_main -N=dcpam_Vlp_T10L50.nml | tee Vlp.log

In this case, 5 days integration is performed. Resolution is T10L50 (Number of grid points of longitude, latitude is 32, 16, and number of vertical layer is 50). History data are output to 'U.nc' and 'Temp.nc' etc., and a restart data is output to 'restart.nc'.
