Boundary Condition Files

 

These files need to be in the directory whose path and name are given by the execution shell script variable bnddir in order for the model to work. In this release, this directory is bnddata.

All files are ASCII formatted vertical lists arranged using standard FORTRAN looping conventions for an array, which first increments the first index, then the second index, and so on. Thus, each line the boundary condition file corresponds to the value of the variable in a spatial domain grid box in the following way:

line 1 corresponds to grid (1,1)
line 2 corresponds to grid (2,1)
line nx corresponds to grid (nx,1)
line corresponds to grid (1,2)

The following datasets are included in the boundary condition directory:

ALBD_Darnell

Climatological monthly observed surface albedo derived from Darnell et al. [22].

CLOUD_ISCCP

Climatological monthly ISCPP cloud cover. This cloud data is used in the radiation scheme by Chou and Neelin [5], which is implemented in clrad1.f90. for model initialization.

SST_Reynolds_oi

Directory containing Reynolds [30] blended SST. See below for more information.

STYPE

Surface type: , , , . Note that the array STYPE is declared REAL 8 in the code.

TOP

Smoothed relative topography; height/10 km (currently the same as the file TOP.smooth).

A package of Fortran programs used to generate boundary data at arbitrary model resolution and domain size is provided. It can be downloaded from the web site

Detailed description of the package can be found in section 1.4.3.
