Coastal cities provide the opportunity to characterize marine clouds and the substantial effects of manmade particles on cloud properties and processes. The Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE) at La Jolla sampled air masses at Scripps Pier and Mt. Soledad that were typically northwesterly, bringing a mixture of urban and marine emissions. DOE ARM cloud, aerosol, and precipitation measurements from February 2023 to February 2024 combined with a multi-institution, international collaboration characterized aerosol particle and cloud droplet size distributions. Statistical analyses of twelve months of observations provide evidence of aerosol-cloud interactions through correlations of paired variables as well as multilinear regressions. Preliminary findings show the near equal contributions of photochemical and aqueous aerosol and cloud submicron sulfate pathways, the modulation of submicron nitrate by the local temperature and relative humidity differences between the two sites, the changes in cloud residual size distributions from cloud supersaturation, substantial differences in drop distributions associated with aerosol source regions, the hygroscopic contributions of sulfur and nitrogen-containing organics as well as of gas-phase components, and the increases in nitrate formation during clouds. Together these results show aerosol-cloud and cloud-aerosol effects, providing important constraints for modeling aerosol indirect effects.
