[MITgcm-support] External temperature forcing

[Menemenlis, Dimitris (3248)]

Jonathan, you can use pkg/rbcs to do what you describe below in arbitrary locations
http://mitgcm.org/public/r2_manual/latest/online_documents/node237.html

But if you are specifically going to force temperature only where there is runoff,
then use RUNOFTEMP as per example in verification/global_ocean.cs32x15/input.seaice
