Paper Abstract

The Visible Infrared Imager Radiometer Suite (VIIRS) is successfully operating on the Suomi National Polar-orbiting Partnership (NPP) observatory, launched on October 28, 2011. Numerous components of the prelaunch test program for sensor bands centered below 1 μm were dictated by the performance requirements for ocean-color (OC) retrievals; several of these characterization activities evolved from those for the legacy sensor, the Moderate Resolution Imaging Spectroradiometer (MODIS). Addition of the Traveling Spectral Radiance and Irradiance Responsivity Calibration Using Uniform Sources (TSIRCUS) laser-based test source provided superior characterization for spectral testing and for radiometric response knowledge. Analysis suggests that band-to-band radiometric uncertainty is well below 0.5% for the OC bands, and resolution of spectral characteristics are known to better than 0.1 nm. The expected improvements in VIIRS performance testing from using T-SIRCUS and some benefits that accrue from these tests are reviewed.
