Subject: CCM formatted SST dataset as b.c.

Hello,
I am writing to ask if a CCM history formated SST dataset
can be used as the lower boundary condition
(when properly reformated as a netCDF dataset) for
a ccm.3.6 run.
I am trying to use an SST dataset obtained from the MSS in
the BNDTVS namelist parameter for a T31 ccm.3.6 run.
The error message
SSTINI: Failed to find dates bracketing mcdate, mcsec= 19680901, 0
is written in stdout.
In the namelists I have specified
NCDATA = '/localdir/SEP1.T31.0198.nc/'
BNDTVS = 'localdir/T31.Dec1949-May1995.nc'
and
SSTCYC = .False.
As can be seen from above, I am specifying the start as 19680901.
The dataset is at /JEFF/sst-monthly/ccm3/nmc/T42.Dec1949-May1995
NCAR system. It is a monthly average time variant dataset from
December of 1949 to May of 1995.
I execuited the following process to make the CCM formated dataset
an netCDF dataset.
executed 'ccm2nc -r8 -C T42.Dec1949-May1995 T42.Dec1949-May1995.nc'
to create the netCDF dataset.
executed 'interpsst -x 96 -y 48 T42.Dec1949-May199.nc T31.Dec1949-May1995.nc'
to interpolate the SST data to T31.
executed 'definesurf -t /localdir/topo.nc T31.Dec1949-May1995.nc'
to rewrite the ORO data.
A few points:
1) The model successfully runs for 1 day when I use the NCAR supplied
dataset sst_jan1978-sep1993.nc (interpolated to T31) in BNDTVS. The model
start date was 19850901.
2) an 'ncdump -v date' indicates that the dates exist
in the datafile T31.Dec1949-May1995.nc.
Any help or suggestions would be greatly appreciated.
Thanks,
Jan Dutton
