Abstract

The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite is a strategic climate continuity mission that will answer new and emerging advanced science questions related to Earth’s changing climate. These science goals are accomplished via PACE’s main optical instrument, a sophisticated spectrograph, the Ocean Color Instrument (OCI) consisting of UV/VIS and VIS/NIR channels each complete with a dichroic, grating, and detector. We will overview the characterization methods used for each component, with respect to its metrology targets, and further discuss how baseline characterization served as a proxy when lines of sight to the optical components’ boresights were lost in later integration steps.
