N2 - Aerosol-cloud interaction contributes to one of the highest uncertainties in radiative forcing estimations. Aerosols from ship emissions alter the cloud properties and have become an important source of anthropogenic air pollution in recent decades. We have measured the size distributions and number concentrations of aerosols in the cloud and outside clouds using various onboard instruments such as cloud droplet probe (CDP; DMT), passive cavity aerosol spectrometer (PCASP, DMT), Scanning Mobility Particle Sizer (SMPS) and Single Particle Soot Photometer (SP2; DMT). The measurements were performed in the ship emission-dominated environments and relatively cleaner regions of the Celtic Sea. We discuss the difference in the characteristics of in-cloud and out-cloud measurements in these relatively contrasting environments. The measurements were made between 29th September and 12th October 2021 using the Facility for Airborne Atmospheric Measurements (FAAM) research aircraft as a part of the Atmospheric Composition and Radiative forcing changes due to UN International Ship Emissions regulations (ACRUISE) Project.
