• Aqua planet experiment module phy_ape is improved.
  • "PhysicsAPE" that calculates all sub-processes is divided into "PhysicsAPE" (radiation, vertical diffusion, surface flux) and "PhysicsAdjust" (moist convective adjustment, large scale condensation, dry convective adjustment). In the result, calculations can be performed in the order similar to AGCM5.
• Modules and a main program for virtual planet experiment like Jovian atmosphere is being created. (under construction)
  • phy_jupiter_case00 is created. This is superior module to following modules and Vertical diffusion flux phy_verdiff, Cumulus parameterization (Convective adjustment scheme) phy_cumulus_adjust, Large scale condensation phy_lscond, Dry convective adjustment phy_dryconv_adjust.
  • phy_cooling_s08 that calculates cooling of atmospheric upper layer to imitate Jupiter is created.
  • phy_sponge_layer module that calculates velocity tendency by sponge layer for damping velocity is created.
  • phy_adjust_fixed module that adjusts some physical values to certain fixed values is created.
• phy_cumulus_adjust is improved.
  • Execution speed is improved.
• phy_lscond is improved.
  • Execution speed is improved.
• A module phy_saturate_nha92 that evaluates saturation specific humidity with Nakajima et al. (1992) is created.
• sigma_data is improved.
  • L5, L23, L45 are added.
• phy_radiation_flux is improved.
  • Prefixes "PhyRadFlux" are added to procedures.
  • Band number and absorption coefficients etc. can be specified from arguments of initialization procedure or NAMELIST.
• A way of specification of NAMELIST about history data output is improved.
• Depended gt4f90io version is changed to "20080603".
• A bug that pre-processes for generation of f90 files mulfuction when Ruby version installed in a system is 1.6 is fixed.
• GOKURAKU dcpam4 is modified.
  • "Notes about some compilers" is created.
• intavr_operate is modified.
  • Following functions are added.
    • ya_IntLon_xya, ya_AvrLon_xya, xa_IntLat_xya, xa_AvrLat_xya
• initial_data is modified.
  • Zonal and meridional wind can be generated.
  • Initial data like a Jovian atmosphere that is used in Sugiyama et al. (2008) is imitated and the data is provided.

• GOKURAKU dcpam4 is created.
• Pages of RAKURAKU dcpam4 is created. (Contents are under construction).
• Initial data is output to history data.

• Depended gt4f90io version is changed to "20071009".
• Aqua planet experiments can be performed. How-to is not prepared yet, but will be prepared in GOKURAKU dcpam4.
• Aqua planet experiment module phy_ape is imported from dcpam3. Following modules needed by this module are imported from dcpam3, too.
  • Operation for integral and average module intavr_operate
  • Sea surface temperature (SST), and various values on surface configuration module phy_ground
  • Temperature, pressure, and geo-potential on half level interpolation module phy_interpolate

  • History data of "xyr_SigmaDot", "xy_DPiDt" can be output.
• Spline curve data generation module spline_data is created.
• initial_data is modified.
  • Mean value of temperature, surface pressure, specific humidity can be configured.
• dcpam4 Credits is changed to Precautionary statement and Licence terms.
• dcmodel_f90sample_maker.rb is modified.
  • History data can be output.
  • Test programs are modified.
  • Error that is occurred when a module name is same as argument keywords is removed. (It is no problem for a module name same as argument keywords).
