Randomized trial observes aerosol populations and dust dynamics in the Southern European Alps, indicating seasonal transport patterns.

This research aims to measure aerosol characteristics and transport dynamics at high elevation to understand their climatic role.
Conducted continuous aerosol measurements at Testa Grigia Observatory from September 2021 to May 2023.
Analyzed aerosol size distribution and absorption coefficients with hourly resolution.
Identified aerosol population types and their transport pathways.
Three distinct aerosol population types were identified, indicating different transport pathways.
Sahara Dust Events accounted for 6% of observations, mainly in spring and early summer.
The influence of the boundary layer on aerosol frequency was up to 28%, affecting PM10 concentration.

A 2026 study studied this question.
