A novel performance assessment approach was developed to inform critical load applications. Model estimates were compared to wet and bulk inorganic N deposition measurements. Model bias and error were expressed as a percentage of regional critical load values. Bias was large relative to or even exceeded critical loads in some cases. This approach may help assess confidence in critical load and exceedance calculations.
