It has been found that the day/night band of the Visible Infrared Imaging Radiometer Suite is capable of observing rapid motions of the aurora. The images that led to this discovery are shown. Shifts in the apparent position of the aurora boundary between consecutive scans of the instrument, which occur ~1.79 s apart, allow the cross-track relative ...

NOAA-20 VIIRS on-Orbit Calibration Improvements
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020The NOAA-20 (N-20) VIIRS has successfully operated for more than two years since its launch in November 2017. Shortly after completing its initial instrument check-outs and post-launch testing (PLT) activities, the N-20 VIIRS sensor data records (SDR) achieved the beta, provisional, and validated maturity status in January, February, and April 2018 ...

One of the roles of the VIIRS Ocean Science Team (VOST) is to assess the performance of the instrument and scientific processing software that generates ocean color parameters such as normalized water-leaving radiances and chlorophyll. A VIIRS data simulator is being developed to help aid in this work.

JPSS VIIRS Ocean Color Products and Applications
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018In this paper, we provide an overview of the progress on producing accurate global ocean color products from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-orbiting Partnership (SNPP) and NOAA-20 satellites. SNPP and NOAA-20 were launched on October 28, 2011 and November 18, 2017, respectively. VIIRS global ocean

Validation of VIIRS Calibrations for Oceans
Imaging and Applied Optics Technical Papers, 2012New methods to create VIIRS ocean-color products are reviewed, with recommendations for handling an on-orbit NIR anomaly, exploiting hyperspectral characterization, and correcting for polarization in an operational data-processing environment.

The impact of VIIRS polarization sensitivity on ocean color
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010The sensitivity to polarized radiance input of the VIIRS instrument (Flight Unit 1 on NPP) has been extensively characterized and shown to be compliant with the sensor specifications [1]. We have rigorously modeled VIIRS measurements of polarized, top-of-atmosphere radiances, using Global Synthetic Data in open ocean regions and a VIIRS sensor model ...

VIIRS On-Orbit Spatial Characterization Using the Moon
IEEE Geoscience and Remote Sensing Letters, 2014The VIIRS instrument onboard the Suomi-NPP satellite was launched in October 2011. The design and operation of its on-orbit calibration system are strongly based on MODIS heritage. However, VIIRS has no onboard calibrator similar to the spectro-radiometric calibration assembly (SRCA) on MODIS to perform the sensor on-orbit spatial characterization of ...

An overview of S-NPP VIIRS lunar calibration
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015The S-NPP VIIRS has operated for more than 3.5 years since its launch in October 2011. The VIIRS reflective solar bands (RSB) calibration is performed by an on-board solar diffuser (SD) and a solar diffuser stability monitor (SDSM). In addition, lunar observations have been used to monitor the RSB on-orbit calibration stability. Since launch, more than
