A method to perform an aqua planet experiment (planetary surface is covered by watar) is described.
Following physical processes are used in this experiment.
This experiment requires data of distribution of sea surface temperature. So, the experiment is performed with the following 4 steps:
Let us move to the top directory of dcpam5 src tree. Here, we perform an experiment in ../dcpam5-exp/ape-exp directory. Please create the directory and enter there as follows:
$ mkdir -p ../dcpam5-exp/ape-exp $ cd ../dcpam5-exp/ape-exp
Then, pleaase create the directories for executable files and configuration files as follows:
$ mkdir bin $ mkdir conf
Finally, executable files and configuration files are copied as follows:
$ cp ../../dcpam5/src/main/dcpam_main bin $ cp ../../dcpam5/src/main/init_data bin $ cp ../../dcpam5/src/main/sst_data bin $ cp ../../dcpam5/exp_setup_files/*.conf conf
Note that you can perform an experiment in any directory by using executable files and configuration (namelist) files.
Create initial data file "init_T21L16.nc" using "init_data" and "init_data_T21L16.conf"
$ ./bin/init_data -N=./conf/init_data_T21L16.nml
:

*** MESSAGE [restart_file_io] *** Input::

*** MESSAGE [restart_file_io] *** IntTime = 1. [day]
*** MESSAGE [HistoryCreate3] *** "init_T21L16.nc" is created (origin=0. [day])

*** MESSAGE [initial_data] *** NAMELIST group "initial_data_nml" is loaded from "./conf/init_data_T21L16.conf".
*** MESSAGE [initial_data] *** ----- Initialization Messages -----

*** MESSAGE [initial_data] *** QVapAvr = 0.1E-09
*** MESSAGE [HistoryClose] *** "init_T21L16.nc" is closed
Next, create SST data "sst_T21.nc" using "sst_data" and "sst_data_T21.conf".
$ ./bin/sst_data -N=./conf/sst_data_T21.conf
:
*** MESSAGE [restart_surftemp_io] *** ----- Initialization Messages -----
*** MESSAGE [restart_surftemp_io] *** Input::
*** MESSAGE [restart_surftemp_io] *** InputFile =
*** MESSAGE [restart_surftemp_io] *** InputName = SurfTemp
*** MESSAGE [restart_surftemp_io] *** Output::

*** MESSAGE [restart_surftemp_io] *** IntTime = 1. [day]
*** MESSAGE [HistoryCreate3] *** "sst_T21.nc" is created (origin=0. [day])
*** MESSAGE [surface_data] *** NAMELIST group "surface_data_nml" is loaded from "sst_data_T21.nml".
*** MESSAGE [surface_data] *** NAMELIST group "surface_data_nml" is loaded from "sst_data_T21.nml".
*** MESSAGE [surface_data] *** ----- Initialization Messages -----
*** MESSAGE [surface_data] *** Pattern = Hosaka et al. (1998)

*** MESSAGE [surface_data] *** HeatCapacity = 0.
*** MESSAGE [surface_data] *** TempFlux = 0.
*** MESSAGE [surface_data] *** SurfCond = 0
*** MESSAGE [HistoryClose] *** "sst_T21.nc" is closed
At the last, run a experiment using "dcpam_main" and "dcpam_ape_T21L16.conf". Resolution is T21L16, time step is 20 minutes. Integration time is 7 days. A restart data file, a restart data file of surface data, and some history data files are output.
$ ./bin/dcpam_main -N=./conf/dcpam_ape_T21L16.conf | tee ape.log
If initial data, surface data, settings of experiments want to be changed, edit "init_data_T21L16.conf", "sst_data_T21.conf", "dcpam_ape_T21L16.conf".
