Description

This dataset holds Level 1B (L1B) calibrated radiance data collected by the Portable Remote Imaging SpectroMeter (PRISM) instrument deployed on a NASA ER-2 aircraft over the southwestern US and eastern Pacific Ocean. The data were acquired in September 2024 for the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX), a field campaign to gather data to support the PACE orbital mission validation. PRISM is a compact image spectrometer that acquires data in the near ultraviolet (UV) to near infrared (IR) spectral bands between 350 and 1050 nanometers with 3.5-nm spectral resolution. PRISM's capabilities make it well suited for studies of aquatic and coastal ecosystems. This dataset includes calibrated radiance and georeferencing information in NetCDF format.
