A package has been created to facilitate the preparation of Topex data
from raw cycle data. It consists of 4 subroutines:

time_res_mssh.f:    extract the topex residuals
                       from raw cycle data.
          input:    tp(cycle).bin
         output:    time_res_mssh(cycle) 

topex_reduced.f:    map the extracted data onto the reduced
                       grid.
          input:    time_res_mssh(cycle),egm96_on_topex.dat,
                    mean.dat,
                    grid_reduced.dat
         output:    topex_reduced_(cycle)

 topex_eqx.f:       read the equatorial crossing times from 
                       the reduced data.
          input:    topex_reduced_(cycle)
         output:    topex_eqx.out

topex_(year).f:     rearrange and prepare data onto standard
                       model grid for use with MPI.
          input:    topex_reduced_(cycle),
                    tp_md_mean.tp_08_08_0207,
                    topex_eqx.out, grid_reduced.dat,                               topex_reduced_flag.out,modelgrid.8x8
         output:    topex_(year)

These programs have been also been ported to Linux from SGI. The
programs reside in /escher4/medea/bnc/Topex_programs and the outputs are
in /escher4/medea/bnc/Topex_data_current.

Currently available data are topex_1993 to topex_1999.
