ACE-ENA stands for Aerosol and Cloud Experiments in the Eastern North Atlantic, and it is a research project focused on studying the interactions between aerosols, clouds, and precipitation in the marine environment of the Eastern North Atlantic. This region is of particular interest due to its high natural aerosol concentrations and cloud cover, making it an ideal location to study the impact of aerosols on cloud formation and precipitation processes. The ACE-ENA project aims to improve understanding of these interactions through field campaigns, data analysis, and modeling efforts.
