Description:

The North Atlantic (NA) ocean is one of the most cloudy regions over the globe and influenced by various types of both natural and anthropogenic aerosols. Previous studies suggest that global climate models have the largest uncertainties in terms of aerosol-cloud interaction simulations in the NA region. Therefore, NA is an interesting and important region for aerosol-cloud interactions studies, which inspires several field campaigns such as the Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) and Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA), and North Atlantic Aerosols and Marine Ecosystems Study (NAAMES), and Cold-Air Outbreaks in the Marine Boundary Layer Experiment (COMBLE). This session seeks contributions from the research, operational, and user communities that utilize the observations from these recent field campaigns to study the aerosol-cloud interactions in the NA region.
