The new multidisciplinary project ADRIAirBURN aims to enhance scientific knowledge on physico-chemical properties of biomass burning aerosols, focusing on chemically reactive organic fraction, and how their ageing in the atmosphere affects air quality, human health and marine environment in coastal aeras. The project focuses on the Adriatic coast, prone to extreme fire hazards, where the impact of biomass burning remains largely unknown. The overall concept of the ADRIAirBURN project will be presented together with the first results of the field campaign conducted during and outside the heating season in the Central Adriatic area combining online and offline measurements.

The Mediterranean Basin is regularly affected by dust transport from the Saharan desert, which has strong implications for the Earth’s energy budget, cloud formation processes, and human health. In our work we present a 21-year climatology of Saharan dust event identification from in-situ measurement at Monte Cimone in northern Italy coupled with backward trajectories. Overall, 15.8 % days affected by dust events, of which most of them lasted one day. We further present analysis from the FLEXPART model and ice-nucleating particle parameterizations to assess the dust transport time and the possible contribution to ice formation in clouds, respectively.

This study analyzes four major dust events (2021–2022) in the Mediterranean using ground-based observations (lidar and sun photometry), trajectory analysis, and satellite data. It examines aerosol optical depth, Ångström exponent, single scattering albedo, and size distributions, revealing significant variability between stations and events. Event C, originating from the Middle East, features smaller, more absorbing particles, confirmed by ground-based in-situ observations. To assess the dust contribution to the total aerosol load, we estimated the DOD-to-AOD ratios using the MIDAS dataset. METAL-WRF simulations assess mineralogical composition and transport effects, providing insights into dust dynamics.

The study investigates aerosol emissions and their effects on air quality and climate in the Western Mediterranean, focusing on Granada. Despite its mid-size and non-industrial profile, the city experiences high pollutant levels. Measurements at urban and mountain stations assessed aerosol transport and atmospheric boundary layer dynamics. Traffic was identified as the dominant black carbon source, with a smaller contribution from biomass burning. The study analyzed vertical pollutant transport, Saharan dust intrusions, and their impact on air quality and the regional radiative balance, offering deeper insights into aerosol behavior in this complex valley-mountain system of the western Mediterranean basin.
