PACE-PAX SeaBASS DOI description: The Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX) was a field campaign to support validation of the PACE mission through a combination of multiple platforms including aircraft (ER-2, CIRPAS Twin Otter), ships (R/V Shearwater, R/V Blissfully), autonomous ocean- and land-based instruments, and collaboration with the PACE Validation Science Teams (e.g.PVST-SBCR and PVST-CALCOFI) and PACE Vicarious Calibration systems (HyperNAV). The PACE-PAX mission took place during the month of September 2024 in Southern and Central California and nearby coastal regions. All PACE-PAX data are to be archived in 3 main data repositories: (1) NASA AIR-LARC for all aircraft data (until final data submission in March 2025 then migrated to the Langley Airborne DAAC), (2) AERONET-MAN for Microtops data, and (3) SeaBASS for all ocean optical, biogeochemical and phytoplankton data. The SeaBASS PACE-PAX DOI is split into 4 main cruises: PACE-PAX_Shearwater (cruise_id=RFDDMM-RS), PACE-PAX_Blissfully (cruise_id=RFDDMM-RB), PACE-PAX_SBCR (cruise_id=RFMMDD-SB), PACE-PAX_CALCOFI (cruise_id=RFMMDD-CL) where DDMM, represent the day and month collection date.
