Abstract

The Joint Polar Satellite System 2 (JPSS-2) Visible Infrared Imaging Radiometer Suite (VIIRS) instrument is the third in a series (S-NPP VIIRS launched in October 2011 and JPSS-1 VIIRS in November 2017) of highly advanced polar-orbiting environmental satellites. JPSS-2 VIIRS underwent a comprehensive sensor-level Thermal Vacuum (TV) testing at the Raytheon's El Segundo facility in the summer of 2017. While the test program provided characterization for many spatial, spectral, and radiometric aspects of the VIIRS sensor performance, this paper focuses on the radiometric performance of the 14 reflective solar bands (RSB) that cover the wavelength range from 0.41 to 2.3 μm. Key calibration parameters, such as the instrument gain, signal- to-noise ratio (SNR), dynamic range and radiometric uniformity, were derived in TV environment for both the primary and redundant electronics at three instrument temperature plateaus: cold, nominal, and hot. This paper shows that all the JPSS-2 VIIRS RSB detectors have been well characterized, with the key performance metrics comparable to those in the prelaunch characterization of the previous two VIIRS instruments. Comparison of radiometric performance to sensor requirements as well as a summary of key sensor testing and performance issues will be presented.
