For the coarse domains (C125 and IP25) emissions from EMEP
database were used (CEIP, 2014) for the year 2012 simulation and
were kept unchanged for 2020. Thus, emissions changes outside
Portugal for 2020 were not considered. Besides its importance to
PM10 concentrations (Monteiro et al., 2015), natural dust
emissions from (Sahara) desert regions were not also considered in
the scope of this study since there are no predictions of dust
emissions for future scenarios.
