Short summary
The TRANSAMA ship-based campaign (April–May 2023) aboard Marion Dufresne investigated aerosols from La Réunion to Barbados using photometer and lidar. Observations revealed clean conditions over the South Atlantic, with thin transported aerosol plumes from Southern Africa. Clouds were detected in 53 % of lidar profiles with higher occurrence in the first 2 km. The results show how combined lidar and photometer measurements can improve our understanding of aerosols in marine environment.
