20.5 Data Preparation Routines

obc.F

This routine is based on the routine PREP_DATA/sponge.F and prepares the open boundary values for T and S. For input it uses the standard Levitus data (prepared by ic.F) or ASCII data written by FERRET (Hankin and Denham 1994). The damping factors have to be specified (search for USER INPUT). Two files, obc1.mom for zonal and obc2.mom for meridional open boundaries, are written. Following ifdefs can be chosen:

makeobc

driver

readferret

use FERRET-data as input (formatted listing); otherwise Levitus-data are used

obc_north, obc_south, obc_west, obc_east

write_netcdf

additional netCDF output

obcpsi.F

This routine prepares open boundary values for $\psi$, required for `active' open boundaries. It uses output (formatted listing) of FERRET. Alternatively values for psi must be given directly in the code. Two files, obcpsi1.mom for zonal and obcpsi2.mom for meridional open boundaries, are written. The same ifdefs as in obc.F can be chosen.
