An improved method for retrieving nighttime aerosol optical thickness from the VIIRS Day/Night Band [PDF]
Atmospheric Measurement Techniques, 2015 Using Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) data, a method, dubbed the "variance method", is developed for retrieving nighttime aerosol optical thickness (τ) values through the examination of the dispersion of ...

The Annual Cycling of Nighttime Lights in India
Remote Sensing, 2021 India is known to have unstable power supply, and many locations show an annual cycle in VIIRS Nighttime Light (VNL). In this study, autocorrelation function (ACF) analysis is used to identify the annual cycling in VNL.

Improved VIIRS Day/Night Band Imagery With Near-Constant Contrast
IEEE Transactions on Geoscience and Remote Sensing, 2014 The Suomi-NPP Visible Infrared Imager Radiometer Suite (VIIRS) instrument provides the next generation of visible/infrared imaging including the day/night band (DNB) with nominal bandwidth from 500 to 900 nm. Previous to VIIRS, the Defense Meteorological Satellite Program Operational Linescan System (OLS) measured radiances that spanned over seven ...
