initial condition files

[maisa@dgf_uchile_cl]

hello,
i would like to do cam run for the years 1997 and 1998. How can I get initial conditions files requeried? (atmospheric and sst??, I guess for ozone, water vapor and aerosol I can just use the data given with the distribution!??

many thanks
maisa

First of all, the sst dataset you require is distributed with the model. The file atm/cam2/sst/sst_HadOIBl_bc_64x128_1949_2001_c020411.nc contains SSTs from 1949 through 2001.

The easiest way to obtain the initial conditions you need is to have the model generate them itself. You'll need to build a namelist containing the following entries (along with the standard entries):
START_YMD = '19960901'
NELAPSE = -123
SSTCYC = .FALSE.
BNDTVS='/sst_HadOIBl_bc_64x128_1949_2001_c020411.nc'

This will start the model integrating on Sep 1, 1996. When it reaches Jan 1, 1997, it will by default write out a set of initial conditions for the land and atmosphere. You may use these for subsequent experiments.
