An Overall Assessment of JPSS-3 VIIRS Radiometric Performance Based on Pre-Launch Testing

Satellite imagery and data are playing an increasingly important role in scientific studies of the Earth its climate. The community has been demanding ever-increasing capabilities accuracy from provided by these satellites. One key instrument on board a series satellite platforms is Visible Infrared Imaging Radiometer Suite (VIIRS), which provides high-quality low orbit covering visible to long-wave infrared parts spectrum. fourth build series, set be launched Joint Polar-orbiting System 3 (JPSS-3) platform, recently completed main ground calibration program integrated into bus near future. This covered comprehensive performance metrics designed demonstrate quality science ensure can maintain successfully once on-orbit. subject this work covers radiometric including dynamic range, signal-to-noise ratio/noise equivalent differential temperature (SNR/NEdT), polarization sensitivity, scattered light response, relative spectral response versus scan angle, uniformity, as well uncertainties; all met or exceeded their design requirements with some minor exceptions. Comparisons previous builds will also provided.
