Hi Martin,

Many thanks for this clarification about the RBCS and other forcing schemes.

All the best,
Paul

Hi Paul,

yes, that’s what it is meant to do, linear interpolation between records in the forcing files. This is true for any forcing file in the MITgcm, exf, rbcs, obcs, default as soon as the “ForcingPeriod” (or time interval between forcing records) is set to values > 0).
