PACE-PAX CIRPAS Twin Otter In-Situ Aerosol Data

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/asdc/suborbital/pace-pax/cirpas-to/large-aerosol_aircraftinsitu_1

PACE-PAX_LARGE-Aerosol_AircraftInSitu_CIRPAS-TO_Data is the in-situ aerosol data collected onboard the Twin Otter aircraft flying the CIRPAS suite of instruments during the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX) campaign.

Description

Data from the Aerodynamic Particle Sizer (APS), Ultra-High Sensitivity Aerosol Spectrometer (UHSAS), TSI-3563 Nephelometer, and Printed Optical Particle Spectrometer (POPS) instruments are featured in this collection.

Data collection for this product is complete. The Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX) was a field campaign to gather data to support PACE mission validation. A secondary objective was help validate data from JAXA/ESA's Earth Cloud, Aerosol, and Radiation Explorer (EarthCARE) mission.

PACE-PAX was conducted in September 2024 in Southern and Central California and nearby coastal regions. The team flew 81 hours on the NASA ER-2 operating out of the NASA Armstrong Flight Research Center and 60 flight hours on the CIRPAS Twin Otter from Marina Municipal Airport. A NOAA vessel, the R/V Shearwater, operated 16 day trips out of Santa Barbara, while a privately owned sailboat, the R/V Blissfully, conducted nine sorties out of Long Beach.

Numerous other entities — many of which were members of the PACE Validation Science Team (PVST) — cooperated to make coincident observations. Ocean data are archived at the SeaWiFS Bio-optical Archive and Storage System (SeaBASS), DOI: 10.5067/SeaBASS/PACE-PAX/DATA001 The PACE-PAX mission website contains additional campaign documentation.
