The Atmospheric Science Data Center (ASDC) has released data for the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX). PACE-PAX is a NASA field campaign that was conducted in September 2024 to gather data for the validation and refinement of data products generated by the PACE satellite mission. PACE-PAX obtained measurements over central and southern California and nearby coastal regions. Two aircraft were flown to obtain measurements for the campaign: the NASA ER-2 high-altitude aircraft, and the CIPRAS Twin Otter aircraft (in situ sampling). Using a robust suite of in situ and remote sensing instruments as well as ground-based observations, PACE-PAX validated and refined PACE data products and identified any potential errors of biases in the measurements, which is essential for ensuring the accuracy and reliability of PACE data products.
We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.
