SoDa can offer a study of dust event frequency and intensity for a given location, based on the analysis of the meteorological METAR codes at the nearest airport. Please find here a typical report which can be produced. The report contains the following sections:

"Does HC3v5 take into account the evolution of the atmospheric dust content?"
HelioClim-3v5 is using the CAMS McClear clear-sky model which takes into account the atmospheric dust.
The McClear model uses the atmospheric amounts of aerosols (dust, carbon, salt, etc ), water vapor and ozone to compute the sunlight scattering and diffusion in its down path through the atmosphere. The amounts of aerosols, water vapor and ozone are computed by ECMWF in the C-IFS numerical weather model.
A recent report from 2017 on the C-IFS model comparison to observations for year 2003 can be found here : http://atmosphere.copernicus.eu/sites/default/files/repository/CAMS84_2015SC2_D84.7.1.2_Y1_v1_0.pdf
The main finding of this report is certainly that CAMS C-IFS underestimates the amount of dust in North Africa and Middle East (chapter 3.1.2, page 27) but is in good qualitative agreement in terms of seasonal variations. For intance, if a big dust event happens, it is likely that the CAMS dust values will be impacted, but they will certainly not show the near extinction of the solar radiation.
