Post-Configuration Information

   Buildconf
   _________

  * make sure ice albedos get set to the following in the namelist:

      dT_mlt    = 1.5_dbl_kind
      rsnw_melt = 1500._dbl_kind


======================
SourceMods Information
======================

  * Activate geothermal heating in pop2 (100 mW/m**2)

    Two modified ocean files are needed for this run: pop2_in_build.csh and vertical_mix.F90.  

    The two files are located in the directory
       /fis/cgd/cseg/people/njn01/test/blowtorch/b40.22.C.blowtorch.03/SourceMods/src.pop2
 
    Copy these two files into the $CASE/SourceMods/src.pop2 directory *before* building
    this case.
    
    -----------------   additional information -------------------------------------
    The pop2_in_build.csh script sets bottom_heat_flx = 0.100 (100 mW/m**2) 
    and the vertical_mix.F90 file fixes a bug, so that now the bottom_heat_flx 
    is properly converted to model units.

    Both of these modified files are based upon the pop2 tag ccsm_pop_2_1_20090812,
    which is used in ccsm4_0_beta22, ccsm4_0_beta23, and is planned to be
    used in ccsm4_0_beta24.
