PACE-PAX ER-2 High Spectral Resolution Lidar-2 Data

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/asdc/suborbital/pace-pax/data001/er2/aircraftremotesensing/hsrl2_1

PACE-PAX_AircraftRemoteSensing_ER2_HSRL2_Data is the High Spectral Resolution Lidar - 2 (HSRL-2) data collected onboard the ER-2 aircraft during the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX) campaign.

Description

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.
