Running WACCM with rotation of the earth reversed



I would like to run the F_2000_WACCM_SC model configuration for CESM 1.2.2 with the direction of rotation of the earth reversed. However, I cannot seem to find an obvious place in the code to make this alteration. How might I go about making this change? Would it involve altering the model code itself? If so, where in the model code might I look to do this?


Thank you very much!

From grepping the code, I found the angular velocity of the Earth is defined in this module:


 real(r8), public, protected :: omega      = shr_const_omega        ! earth rot ~ rad/sec

     omega       = 2.0_R8*pi/sday

You could try setting that to the negative of that value. I do not know if there are other places in the code where this is defined. You might also ask about this in the CAM forum here.
