Abstract

ALICENET (https://www.alice-net.eu/) is the Italian network of Automated Lidar-Ceilometers (ALCs) operationally (24/7) measuring aerosol profiles and clouds, and contributing to the European E-PROFILE EUMETNET program (https://www.eumetnet.eu/activities/observations-programme/current-activities/e- profile/. ALICENET is a consortium network coordinated by CNR-ISAC and involving several regional EPAs (ARPAs) and Universities/Research centres. Recent advancements in system technology and a centralized data processing allow providing homogeneous quantitative information on aerosol optical and physical properties across the country. This includes aerosol backscatter profiles (Wiegner et al., 2014), estimation of aerosol extinction, surface area, volume and mass profiles (Dionisi et al., 2018), information on the mixing layer (Poltera et al., 2017, Kotthaus et al., 2020) and on presence and vertical displacement of elevated aerosol layers. The geographical distribution of the ALICENET systems, extending from the north to the south of the country (Figure 1), allows investigating aerosol features over a wide range of atmospheric and environmental contexts. In fact, the network covers areas dominated by anthropogenic aerosols (e.g. the Po Basin and the main urban areas of the country, Milan and Rome, e.g., Diémoz et al., 2019a, b), those highly affected by desert dust advections (e.g. Sicily, Central and Southern Italy, e.g. Barnaba et al., 2017, Gobbi et al., 2019, Barnaba et al., 2022), and those influenced by volcanic ash, near the Etna volcano. In some stations the experimental setup includes polarization-sensitive ALCs, co-located passive remote sensors (e.g. sun photometers), and surface in situ measurements of aerosol optical and physical properties.
