Abstract/Summary

The MITgcm (MIT General Circulation Model) is a numerical model designed for study of the atmosphere, ocean, and climate (Marshall et al. 1997a,b). Its non-hydrostatic formulation enables it to simulate fluid phenomena over a wide range of scales; its adjoint capability enables it to be applied to sensitivity analysis and state estimation problems. By employing fluid isomorphisms, one hydrodynamical kernel can be used to simulate flow in both the atmosphere and ocean. This report describes the work undertaken under the embedded CSE programm of the ARCHER UK National Supercomputing Service, and was entitled "Providing the ARCHER community with adjoint modelling tools for high-performance oceanographic and cryospheric computation", where the main proposer was Dr Dan Jones (British Antarctic Survey, or BAS), with co-proposers Dr Dan Goldberg (University of Edinburgh, or UoE), Dr Paul Holland (BAS), and Dr David Ferreira (Reading University). The technical work, performed by Dr Sudipta Goswami (BAS) and Dr Gavin Pringle (UoE), was undertaken between mid-February and mid-December, 2015. A recent version of MITgcm, namely version c65i, has been ported to ARCHER for all ARCHER users
