EPCAPE Concludes: Unprecedented Data on California Coastal Marine Clouds

The Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE) has concluded its yearlong observational phase, leaving behind an unprecedented wealth of data on coastal marine stratus. Led by a team of 17 co-investigators, the campaign has produced the most detailed probing of California coastal marine stratus to date.

EPCAPE, designed to study marine stratus clouds and their radiative effects, was a collaborative effort involving universities, national labs, NASA, and Environment and Climate Change Canada. The Department of Energy's Atmospheric Radiation Measurement (ARM) user facility supplied the main instrumentation, with additional support from partners. The campaign utilised ARM's portable atmospheric observatory, AMF1, stationed along Scripps Pier, and supplementary instruments on Mount Soledad.

The experiment yielded remarkable results, with more clouds, data, and investigators than initially anticipated. Lynn Russell, a distinguished professor of climate and atmospheric sciences at UC San Diego, served as the principal investigator. The majority of the year's direct measurements are now freely available in the ARM Data Center and UC San Diego's digital library collections.

EPCAPE's successful completion marks a significant advancement in our understanding of coastal marine clouds and their human-made particle influence. The extensive data collected will contribute to future climate and atmospheric research, furthering our knowledge of these crucial weather phenomena.
