Ocean Parameter Uncertainty

Atmosphere-ocean general circulation models are the best tools available to provide policy-relevant predictions of the climate's response to a change in the amount of atmospheric CO2. They include parameterisations of physical processes that cannot be resolved explicitly. There is uncertainty in the numerical values (parameters) involved in the parameterisation of ocean physics. This is called ocean parameter uncertainty. My work was the first investigation of the effects of this uncertainty in a complex climate model.
