Final report on model developments and their evaluation in coupled mode

Interim report, that includes aspects related to: (i) changes in the various components of the Arctic surface energy budget (radiative, turbulent); (ii) changes in the transfer of momentum from the atmosphere to the ocean; (iii) the overall realism of the simulated climate system; (iv) effects on the Arctic Ocean circulation; and (v) changes in the Arctic climate sensitivity in the +1%CO2 simulation.
