Day/Night Band Provides Critical and Unique Support Capabilities to Natural Hazards
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019In the last several years, the new generation of weather satellites, including GOES-16 and NOAA-20, have gone operational, providing higher temporal, spatial, spectral, and radiometric resolution data and derived products. In particular, the latest generation of United States polar satellites offer unique sensitivity capabilities.

Vicarious Validation of Straylight Correction for VIIRS Day/Night Band Using Dome-C
Proceedings of SPIE, 2015The Day/Night Band (DNB) of the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard Suomi National Polar-orbiting Partnership (Suomi-NPP) represents a major advancement in night time imaging capabilities. The VIIRS DNB sensor is affected by stray light. Straylight effect on the DNB instrument is due to solar illumination entering the optical path

Assessment of VIIRS day-night band high gain calibration using stars
Sensors, Systems, and Next-Generation Satellites XXV, 2021The VIIRS has a unique spectral band that can sense reflected light from space during both day and nighttime, thus referred to as the day-night band (DNB). This band operates in three different gain stages: low, mid, and high gain (LG, MG, and HG) that cover a remarkable dynamic range with its HG stage being extremely sensitive to low-light scenes ...

Detection limit of fishing boats by the day night band (DNB) on VIIRS
SPIE Proceedings, 2016The detection limit of DNB was proposed as a function of the brightness temperature (BT) at 3.7 μm, where the transmittance of cloud could be observed as a change of surface temperature. The shortwave infrared band exhibited a wide distribution in BT more than the thermal infrared band for the same level of DNB radiance.

VIIRS day-night band (DNB) electronic hysteresis: characterization and correction
SPIE Proceedings, 2016The VIIRS Day-Night Band (DNB) offers measurements over a dynamic range from full daylight to the dimmest nighttime. This makes radiometric calibration difficult because effects that are otherwise negligible become significant for the DNB. One of these effects is electronic hysteresis and this paper evaluates this effect and its impact on calibration ...

JPSS-2 VIIRS day-night band pre-launch characterization
Sensors, Systems, and Next-Generation Satellites XXII, 2018The JPSS-2 VIIRS instrument much like its predecessors JPSS-1 VIIRS (now renamed NOAA-20) and S-NPP VIIRS has an innovative three gain stage Day-Night Band (DNB) will provide high quality imagery of the Earth over a wide range of illumination conditions.

VIIRS Day/Night Band (DNB) Stray Light Characterization and Correction
Proceedings of SPIE, 2013The Day/Night Band (DNB) on the VIIRS sensor is a panchromatic band that can detect very dim nighttime scenes. After launch of Suomi NPP in October 2011 we observed a gray haze in radiance images with offsets up to 5×10-9 W cm-2 sr-1. Overall this impacts about 25% of nighttime scenes.

Suomi-NPP VIIRS day–night band on-orbit calibration and performance
Journal of Applied Remote Sensing, 2017The Suomi national polar-orbiting partnership Visible Infrared Imaging Radiometer Suite (VIIRS) instrument has successfully operated since its launch in October 2011. The VIIRS day–night band (DNB) is a panchromatic channel covering wavelengths from 0.5 to 0.9 μm that is capable of observing Earth scenes during both daytime and nighttime at a spatial ...

Using the moon and stars for VIIRS day/night band on-orbit calibration
Sensors, Systems, and Next-Generation Satellites XXIII, 2019Two VIIRS instruments are currently operated in space; one on-board the S-NPP satellite launched in October, 2011 and another on-board the NOAA-20 satellite launched in November, 2017. The VIIRS design has included a unique day/night band (DNB), which can make both daytime and nighttime observations in the reflective solar spectral region.

An overview of NASA VCST SNPP VIIRS day-night band on-orbit calibration methodology
SPIE Proceedings, 2014The Day-Night Band (DNB) on Suomi-NPP VIIRS is a visible/near-Infrared panchromatic band capable of observing the earth during both daytime and nighttime. The VIIRS DNB is the first in its class to have on-orbit radiometric calibration using on-board calibrators.
