13 September 2011 Optical component performance for the Ocean Radiometer for Carbon Assessment (ORCA)
Author Affiliations +
The Ocean Radiometer for Carbon Assessment (ORCA) is a new design for the next generation remote sensing of ocean biology and biogeochemistry. ORCA is configured to meet all the measurement requirements of the Decadal Survey Aerosol, Cloud, and Ecology (ACE ), the Ocean Ecosystem (OES) radiometer and the Pre-ACE climate data continuity mission (PACE). Under the auspices of a 2007 grant from NASA Research Opportunity in Space and Earth Science (ROSES) and the Instrument Incubator Program (IIP) , a team at the Goddard Space Flight Center (GSFC) has been working on a functional prototype with flightlike fore and aft optics and scan mechanisms. As part of the development efforts to bring ORCA closer to a flight configuration, we have conducted component-level optical testing using standard spectrophometers and system-level characterizations using nonflight commercial off-the-shelf (COTS) focal plane array detectors. Although these arrays would not be able to handle flight data rates, they are adequate for optical alignment and performance testing. The purpose of this presentation is to describe the results of this testing performed at GSFC and the National Institute of Standards and Technology (NIST) at the component and system level. Specifically, we show results for ORCA's spectral calibration ranging from the near UV, visible, and near-infrared spectral regions.
