The Visible Infrared Imaging Radiometer Suite (VIIRS) is a scanning radiometercontaining 22 spectral bands that is currently collecting data aboard the Suomi-NPP satellite. A second flight unit is set to launch aboard the JPSS-1 satellite in the 4th quarter of 2017 followed by a third one aboard JPSS-2 in 2022. The VIIRS sensor is designed to obtain high quality data products over a variety of conditions including high contrast scenes like bright clouds over ocean for example. In the pre-launch test program the vendor, Raytheon, made measurements to determine the contamination from Near Field Response (NFR), which is scattered light from bright targets, to characterize these features and compare them against the structured scene requirement. As of now prelaunch testing has been completed on the first three VIIRS flight units, S-NPP, JPSS-1 and JPSS-2, with independent analyses performed by the NASA VCST team. We present this NFR characterization including derivation of the Harvey-Shack coefficients and impacts from other contamination such as retro reflections off the dewar to the cold focal planes.
