Descrizione
For the first time, we present the results obtained from an innovative instrument purchased with the support of the ITINERIS project within the European Research Infrastructure Consortium – Aerosols, Clouds, and Trace gas Research InfraStructure (ERIC-ACTRIS). Light Detection and Ranging (LIDAR) techniques have proven to be a highly reliable tool for studying both the atmospheric domain, with several applications to study aerosols and water cycle, and the marine environment to measure sea temperature profiles, oil spills, chlorophyll-a concentration and Ocean Colour parameters.
In this context, we present the first Raman depolarisation fluorescence LIDAR instrument capable of combining atmospheric and oceanic measurements. Active remote sensing of marine aerosols and air-sea interface processes using a pulsed laser will enable the development of new combined atmospheric and marine LIDAR products. It will also allow for the regular monitoring of relevant atmospheric and marine variables, as well as innovative studies on air-sea interaction. The instrument can be used in conjunction with the automatic photometer installed on the observation deck of the National Research Council (CNR) oceanographic vessel “Gaia Blu”.
This presentation shows preliminary near-real-time data results from the R/V Gaia Blu during the ITINERIS' EYES oceanographic campaign conducted in Mediterranean waters in July 2025, which involved multi-platform experiments to acquire several Essential Variables (EVs).
Studying and observing marine aerosols and physical processes at the air-sea interface, the role of which in climate regulation is poorly understood, will help us to gain a more comprehensive understanding of changes in air quality and climate caused by human activities.
