From Eqs. (2e4), it can be seen that for analysing any emission
reduction scenario, AERIS considers the sum of the contributions
of the respective TMs of those sectors on which emission reductions
have concentrated. Modelling air quality levels in such a
way obviously constitutes a simplification (i.e. linearization) of
the complex deterministic processes that are described by the
AQMS and is very likely to be a limiting factor in the model’s
robustness. The analysis of these potential limitations is
addressed in Section 3.
