The components perturb i) the atmospheric forcing, provided as input the atmospheric parameter standard deviation and possibly, the temporal decorrelation scale of the perturbations. These perturbations are correlated in time and space, and the user can choose the correlation scales; ii) the model tendencies within a number of user-selected tendencies (e.g. tracer diffusion, solar penetration, etc.). Perturbations are collinear to the tendencies and the user can choose the decorrelation scales of the perturbations; iii) selected namelist parameters, provided a user-compiled range of values for the individual parameters (e.g. vertical eddy viscosity, etc.).[[BR]] ''' Science Reviewer:''' [[BR]] ''' System Reviewer:''' [[BR]] ''' Deadline: ''' March 2015 [[BR]] ''' Priority: ''' LOW-MEDIUM [[BR]] ''' Depends on: ''' [[BR]] ''' Principal Investigator : ''' A.
