SUOMI NPP VIIRS reflective solar band radiometric calibration

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The Visible-Infrared Imaging Radiometer Suite (VIIRS) is a primary sensor onboard the National Polar-orbiting Partnership (NPP) satellite launched on October 28, 2011. It collects data over the spectral range of 0.4–12.5 um and consists of 15 reflective solar bands (RSB) and 7 thermal emissive bands (TEB).

Suomi-NPP VIIRS Solar Diffuser Stability Monitor Performance

IEEE Transactions on Geoscience and Remote Sensing, 2016
When illuminated by the Sun, the onboard solar diffuser (SD) panel provides a known spectral radiance source to calibrate the reflective solar bands of the Visible Infrared Imaging Radiometer Suite on the Suomi-NPP satellite. The SD bidirectional reflectance distribution function (BRDF) degrades over time due to solar exposure, and this degradation is ...

Prediction of S-NPP VIIRS DNB gains and dark offsets

Earth Observing Systems XXII, 2017
We describe the methodology for predicting the S-NPP VIIRS Day-Night-Band (DNB) detector gains and dark offsets. During the first 5 years of operation, the DNB has shown recognizable patterns in these calibration parameters. These patterns can be decomposed into two distinctive components: degradation and oscillation. We fit the historical data using a

Prediction of S-NPP VIIRS DNB stray light correction

Earth Observing Systems XXII, 2017
The VIIRS Day-Night-Band (DNB) is a panchromatic band with three gain stages used for delivering imagery under conditions ranging from daylight to low light nighttime scenes. Early in the S-NPP mission a gray haze was observed in some nighttime DNB imagery with the cause determined to be stray light contamination.

Identifying Shrinking Cities with NPP-VIIRS Nightlight Data in China

Journal of the Urban Planning and Development Division, ASCE, 2020
Abstract Although there has been a rapid urbanization in China since the 1980s, the simultaneous urban shrinkage phenomenon has existed for a long time.

Suomi-NPP VIIRS day/night band calibration with stars

SPIE Proceedings, 2015
Observations of stars can be used to calibrate the radiometric performance of the Day/Night Band (DNB) of the Suomi-NPP instrument VIIRS. Bright stars are normally visible in the Space View window. In this paper, we describe several potential applications of stellar observations with preliminary results for several.

NPP VIIRS early on-orbit solar diffuser degradation results

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The Visible-Infrared Imaging Radiometer Suite (VIIRS) was launched October 28, 2011 on-board the Suomi National Polar-orbiting Partnership (NPP) spacecraft as a primary sensor. It has 22 bands: 14 reflective solar bands (RSBs), 7 thermal emissive bands (TEBs) and a Day Night Band (DNB).

SUOMI NPP VIIRS emissive band radiance calibration and analysis

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
VIIRS thermal emissive bands (TEB) have been analyzed. The analysis results indicate the VIIRS TEB is stable and exceeds the specification. Comparisons between the VIIRS and other sensors such as AVHRR, MODIS and CrIS demonstrated that VIIRS TEB agrees well with those sensors. Using Community Radiative Transfer Model (CRTM), developed at U.S.

Initial results of NPP VIIRS SST processing at NAVOCEANO

SPIE Proceedings, 2012
The Suomi National Polar-orbiting Partnership (NPP) satellite was placed in orbit October 28, 2011, and began providing advanced imaging and radiometric data from the Visible Infrared Imager Radiometer Suite (VIIRS) in December 2011. The Naval Oceanographic Office (NAVOCEANO) is processing the VIIRS data as part of the generation of sea surface ...

First-Light Imagery from Suomi NPP VIIRS

Bulletin of the American Meteorological Society, 2013
The Suomi National Polar-Orbiting Partnership (NPP) satellite was launched on 28 October 2011, heralding the next generation of operational U.S. polar-orbiting satellites. It carries the Visible– Infrared Imaging Radiometer Suite (VIIRS), a 22-band visible/infrared sensor that combines many of the best aspects of the NOAA Advanced Very High Resolution ...
