abstract = {The Iberian Peninsula (IP), where this study is conducted, has experienced an increase of the frequency and
intensity of Saharan aerosol dust outbreaks over the latest decades, which may have an impact on its regional
climate. The Weather Research and Forecasting model coupled with chemistry (WRF-chem) has been used
worldwide to simulate dust outbreaks and can support the analysis of such potential impacts. However, it includes
multiple alternative aerosol parameterization choices that have not been conveniently evaluated in the
study region yet. Here, three of the most popular WRF-chem aerosol parameterization schemes, namely, the
Goddard Chemistry Aerosol Radiation and Transport (GOCART), the Model for Simulating Aerosol Interactions
and Chemistry (MOSAIC) and the Modal Aerosol Dynamics Model for Europe (MADE) schemes, are intercompared
during a strong and dry dust outbreak on July 2021 in southern IP. The results show that the three
schemes predict qualitatively similar dust intrusion patterns that are consistent with ground observations and
have inter-model dust loading differences smaller than 4%. However, their average dust size distributions differ
notably. While GOCART is reasonably consistent with observations, MOSAIC underpredicts the amount of dust
particles with sub-micron diameters and overpredicts that of large particles and MADE does the opposite. This is
found to have a strong detrimental impact on the prediction performance of dust optical properties in MOSAIC
and MADE, which is related, at least partially, with issues in the required inter-sectional redistribution of dust
parameters during the dust emission and calculation of optical properties. Overall, GOCART generally appears a
better choice for strong and dry dust outbreak events in southern IP. It remains to be evaluated during wet dust
outbreaks, which is a work underway.},
