An ad hoc procedure by which the values of dependent variables at the air-sea interface in coupled atmosphere-ocean model runs are adjusted to better conform to observed values. For example, heat flux is corrected by first running the ocean model and calculating the heat flux needed to correct the differences between the observed and calculated surface temperatures. Next the atmospheric model is run with observed values of SST and the net heat flux from the atmosphere is calculated. The coupled model is then run with the difference between these ocean and atmospheric heat fluxes added to those calculated by the coupled model at each time step. A similar procedure can be followed with other variables. These methods are designed to remove most of the tendency of coupled models to drift towards their own climate replete with systematic errors. The most difficult area to apply this procedure is over ice. It is expected that this will become much less of an issue as the model components are improved.
