Short summary
The main objective of this study is to reinforce the observations of new particle formation (NPF) events in the Southern Hemisphere and more particularly for a site that is both marine and at altitude, the Maïdo observatory (2150 m), on Réunion. We recorded a high annual NPF frequency of 65 % and we note that monthly averages show a bimodal variation. We estimate the intensity and the characteristics of the events and describe their seasonality by comparing them to other parameters.
