I have a question about whether there's a need to spin up for branch runs. Specifically, I am using a restart file dated 1955-01-01, but the STARTDATE is defaulted to 1979-01-01 and cannot be changed due to the branch run's constraints. Can I assume that performing a branch run from a preset STARTDATE (1979-01-01) far ahead from the restart file's REFDATE (e.g., 1955-01-01) means that the model has already been spun up to a stable state by that year (1979-01-01)? Thus eliminating the need for additional spin-up?
Thanks in advance for any suggestions/clarifications/help.
