Hello,I’m using CMAQ_5.2-DDM-3D.When I want to run the run_cctm.csh for using sensitivity bc file for nested runs ,I set as follows：
setenv DDM3D_BCS T # use sensitivity bc file for nested runs [ T | Y | F | N ] (default is N/F)
set S_BCpath =
set S_BCfile =
But,I don not know how to set “S_BCfile”. Would you please help me with the problem?
Thanks for your time
