The NA-CORDEX archive includes CRCM5-UQAM simulations driven by the GEMatm AGCM.
The GEMatm AGCM is essentially a global version of CRCM5. It uses sea ice and sea-surface temperatures (SSTs) from a separate GCM simulation as lower boundary conditions over the ocean for a one-degree global atmosphere-only simulation. The SSTs are empirically corrected by subtracting their historical bias. The AGCM-simulated atmospheric fields and the corrected SSTs are then used to drive the RCM at higher resolution over the CORDEX domain.
These AGCM simulations are named GEMatm-[GCM] in the archive, where [GCM] is an abbreviated version of the GCM providing the SSTs:
