The Poseidon Project will deliver a nominally 1km resolution global ocean circulation solution. That’s under development at this time. Meanwhile, several test solutions are available, including:
A subset of global LLC4320 data (MITgcm). The LLC4320 solution is a prototype for the Poseidon Run.
Several regional 1km resolution simulations of the sub-polar North Atlantic and Nordic Seas (MITgcm).
A subset of the global LLC90 ECCO data (MITgcm).
A subset of global nominally 1km resolution HYCOM data. We’re working with the HYCOM team to include data from their solutions in the Poseidon Project.
