Metamodeling of Droplet Activation for Global Climate Models2013 ). Constructing lookup tables of detailed parcel model results can be considered a form of model emulation combining a cache of known results and local polynomial (linear) approximation. As the degrees of freedom and number of parameters describing a given aerosol population in a model increase, the burden of saving enough known points to interpolate through the parameter space via lookup table to some reasonable accuracy increases algebraically. For instance, the CESM features a modal aerosol
