This document is tutorial for performing experiments easily with dcpam5.
As an aside, "RAKURAKU" means "easier".
Build dcpam5 referring to dcpam5 Installation Guide. Work until "Compile source code" in "How to build".
After building, executable files dcpam_main, init_data, sst_data are created under "src/main" directory. Some NAMELIST files (with suffix ".nml") are prepared in the directory.
$ ls src/main
dcpam_ape_T21L16.nml
dcpam_ape_T42L16.nml
dcpam_hs94_T21L20.nml
dcpam_hs94_T42L20.nml
dcpam_main
dcpam_main.F90
init_data
init_data.F90
init_data_T21L16.nml
init_data_T42L16.nml
sst_data
sst_data.F90
sst_data_T21.nml
sst_data_T42.nml

Notes about some compilers that are done the operation check or have done are as follows.
Read it through if the following operation check doesn't go well, because it is likely to apply about other compilers.
Experiments using dcpam5 are performed with the following 4 steps:
Note that several experiments can share a directory for experiments, and an initial condition data can be shared with several experiments. On the one hand, an initial condition data can be generated internally when the experiments are performed without preparing an initial condition. This is also the case for additional data for experiments.
In the followings, methods for performing several experiments are described.
A method to perform a baroclinic wave experiment by Polvani et al. (2004) is described here.
A method to perform dynamical core experiment proposed by Held and Suarez (1994) is described here.
A method to perform an aqua planet experiment (planetary surface is covered by watar) is described here.
A method to perform an aqua planet experiment (planetary surface is covered by watar) proposed by Neal and Hoskins (2001) is described here.
A method to perform an experiment for Earth-like planet is described here.
A method to perform a Mars experiment is described here.
A method to perform an experiment for Venus-like planet by using forcing by Yamamoto and Takahashi (2003) is described here.

Ways how to change several experimental setup is described here.
After editing files under "src" directory, update of contents in a directory for a experiment under "practice" is performed easily as follows. If you edit Fortran 90/95 programs under "src", see RAKURAKU (easier) dcpam5 (under construction) for detail.
Forst, move a directory for a experiment under "practice".
$ cd practice/testXX
Input a following command. A question whether update them may be displayed, then input "Y".
$ make update Update directory "testXX" ? [y/N]: Y
Updated files under "src" directory are copied into "practice/testXX". Old files are renamed to filenames with suffixes ".bak.XX".
