PACE-PAX_Analysis_ISARA_Data is the In-Situ Aerosol Retrieval Algorithm (ISARA) analysis 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. 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.
