VIIRS on-orbit calibration methodology and performance
The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor aboard the Suomi National Polar‐orbiting Partnership spacecraft has successfully operated since its launch in October 2011. The VIIRS collects data in 22 spectral bands that are calibrated by a set of onboard calibrators (OBC). In addition...

| description | The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor aboard the Suomi National Polar‐orbiting Partnership spacecraft has successfully operated since its launch in October 2011. The VIIRS collects data in 22 spectral bands that are calibrated by a set of onboard calibrators (OBC). In addition, lunar observations are made to independently track VIIRS long‐term calibration stability for the reflective solar bands (RSB). This paper provides an overview of VIIRS OBC functions as well as its on‐orbit operation and calibration activities. It also describes sensor calibration methodologies and demonstrates VIIRS on‐orbit performance from launch to present. Results reported in this paper include on‐orbit changes in sensor spectral band responses, detector noise characterization, and key calibration parameters. Issues identified and their potential impacts on sensor calibration are also discussed. Since launch, the VIIRS instrument nominal operation temperature has been stable to within ±1.0 K. The cold focal plane temperatures have been well controlled, with variations of less than 20 mK over a period of 1.5 years. In general, changes in thermal emissive bands (TEB) detector responses have been less than 0.5%. Despite large response degradation in several near‐infrared and short‐wave infrared bands and large SD degradation at short visible wavelengths, the VIIRS sensor and OBC overall performance has been excellent postlaunch. The degradation caused by the telescope mirror coating contamination has been modeled and its impact addressed through the use of modulated relative spectral response in the improved calibration and the current sensor data record data production. Based on current instrument characteristics and performance, it is expected that the VIIRS calibration will continue to meet its design requirements, including RSB detector signal to noise ratio and TEB detector noise equivalent temperature difference, throughout its 7 year design lifetime.
