Added the Source modifications needed to run the SST pacemaker experiments
This configuration enables running SST pacemaker experiments with NorESM2. The SST pacemaker configuration allows Sea surface temperature (SST) to be prescribed over selected regions while maintaining interactive coupling elsewhere. The pacemaker region is currently set for the Kuroshio region; can be modified by updating the mask file. The SST data used here is from the coupled MX run of NorESM2 (0.125° ocean and 1° atmosphere).
This work was done under my PhD project, supervised by Camille Li, Aleksi Nummelin, and Ingo Bethke.
Just as a brief comment: since the BLOM code development has moved/is moving fast, it would be at least good to refer to a certain git-sha (and/or tag) in the README.md for which this code is suitable (both, BLOM and NorESM tags/shas).
@jmaerz, note that this PR is going into the noresm2 branch since these experiments were done on the NorESM2.0 code base. These modifications will be merged and tagged there for publication purposes.
