  "description": "Abstract. The main uncertainties regarding the estimation of changes in the Earth's\nenergy budget are related to the role of atmospheric aerosols. These changes\nare caused by aerosol\u2013radiation (ARIs) and aerosol\u2013cloud interactions (ACIs),\nwhich heavily depend on aerosol properties. Since the 1980s, many\ninternational modeling initiatives have studied atmospheric aerosols and\ntheir climate effects. Phase 3 of the Air Quality Modelling Evaluation\nInternational Initiative (AQMEII) focuses on evaluating and intercomparing\nregional and linked global/regional modeling systems by collaborating with\nthe Task Force on the Hemispheric Transport of Air Pollution Phase 2 (HTAP2)\ninitiative. Within this framework, the main aim of this work is the\nassessment of the representation of aerosol optical depth (AOD) and the\n\u00c5ngstr\u00f6m exponent (AE) in AQMEII Phase 3 simulations over Europe. The\nevaluation was made using remote-sensing data from the Moderate Resolution\nImaging Spectroradiometer (MODIS) sensors aboard the Terra and Aqua\nplatforms, and the instruments belonging to the ground-based Aerosol\nRobotic Network (AERONET) and the Maritime Aerosol Network (MAN). Overall,\nthe skills of AQMEII simulations when representing AOD (mean absolute errors\nfrom 0.05 to 0.30) produced lower errors than for the AE (mean absolute\nerrors from 0.30 to 1). Regardless of the models or the emissions used,\nmodels were skillful at representing the low and mean AOD values observed\n(below 0.5). However, high values (around 1.0) were overpredicted for biomass\nburning episodes, due to an underestimation in the common fires' emissions,\nand were overestimated for coarse particles \u2013 principally desert dust \u2013 related\nto the boundary conditions. Despite this behavior, the spatial and temporal\nvariability of AOD was better represented by all the models than AE\nvariability, which was strongly underestimated in all the simulations.\nNoticeably, the impact of the model selection when representing aerosol\noptical properties is higher than the use of different emission inventories.\nOn the other hand, the influence of ARIs and ACIs has a little visible impact\ncompared to the impact of the model used.",
