The Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE) will take advantage of the coastal location of La Jolla, California to characterize the extent, radiative properties, aerosol interactions, and precipitation characteristics of stratocumulus clouds in the Eastern Pacific across all four seasons at the Scripps Pier and the Mt. Soledad. The focus of the EPCAPEFILTERS project is to enhance the aerosol measurements at the Scripps Pier by providing organic and elemental filter analyses for chemical tracers to supplement the non-refractory chemical measurements provided by the AMF1 Aerosol Observing System (AOS). Since the aerosol in the region ranges from a clean marine background to frequent intrusions from a large and regionally homogeneous, well-characterized, surface-based pollution source (the Los Angeles-Long Beach urban port megacity), this project is relevant to the DOE mission because it will enable improved and expanded scientific studies by identifying aerosol source contributions during EPCAPE measurements.
