[MITgcm-support] OBCS Error with 36km Arctic config

[Patrick Heimbach]

Hi there,

indeed, as Alessandro mentioned, the file containing open boundary conditions for this setup ends in July 2002 (coincident with end of ERA-40 atmos. reanalysis, the ones used at the time this setup was first produced). The setup provided should be thought of more as a tutorial than a “production” setup.
