[MITgcm-support] Nudging SST data into MITgcm

there are plenty of different ways of relaxation (which is the same as nudging) to surface fields, and even to 3D fields, depending on what you want to do exactly. 

Please have a look at the tutorials in the documentation and at the verifications experiments, which have a lot of examples; with pkg/exf the relevant parameter names contain climsst, without pkg/exf the parameters are tauThetaClimRelax, thetaClimFile, etc.
