How to set the orbital parameter acceleration in CESM1.0?

all your questions are answered in the documentation: http://www.cesm.ucar.edu/models/cesm1.2/cesm/doc/modelnl/nl_drv.html note that you should only modify the code if you want to do something that is not already built in to the coupler.  based on your explanation, you may want to explore the "variable_year" option of orb_mode... which may satisfy your needs w/o modifying code.   good luck!
 
Hi shilds, Thanks for your suggestion.We have tried out the experiment with the "variable_year" option of orb_mode, but in this case, the orbital parameters varied year to year. we just want the orbital parameters to change decade by decade per one model year. Can we realize it just only change the option of orb_mode to "variable_year" ?  Do you have any suggestions, that would be much appreciated. Xiao
