Question about CAM4 initial condition

[lawnglo@yahoo_com_hk]

I'm a beginner in CESM. I'm using F_2000 component set and I felt confused about the initial conditions by default setting. How to create the climatological forcing files (cami_1987-01-01_0.9x1.25_L26_c060703.nc). Is it observational data or spining up data from CAM? More, How can the CESM create prescibed ozone (ozone_1.9x2.5_L26_2000clim_c091112.nc) and other gases (sulfate_camrt_c080918.nc ..) Are they coming from observation data/ Measurement data? How can I know more detail about initial condition? Does anyone know?
Thanks!

Hi Kan,Initial conditions are produced by the model, either from a previous similar simulation, or a spinnup simulation. The climatological forcing files are also created from output of a  previous full chemistry simulation. Those data sets are created after a long run has been performed. Simone

Hi Tilmes,

How can create the initial conditions for 1980 -01-01 ? I need to create Initial conditions for this time and want to run simulation till 2020.

I'm using F_2000 component set and need to define initial conditions for this time at 1980.

Can you give me suggestion.

Thank you in advance.
