Highlights:
- Characterization of aerosol properties is performed for the first time at the Alpine site of Saint-Christophe, Aosta (Italy). The AOD at the station is generally very low (0.10 at 500nm), however spikes (up to 0.75) can occur due to the transport of Saharan dust and smoke clouds moving on an intercontinental scale.
- SKYRAD and SUNRAD aerosol optical depths and Ångström exponents are compared, providing consistent results. Spectral variation of the Ångström exponent is also employed to discriminate between different types of particles.
- Influence by local meteorology and anthropogenic emissions is investigated, providing useful information to understand the pollution dynamics in mountainous regions.
