A Test of the New VIIRS Lights Data Set: Population and Economic Output in Africa

open access: yesRemote Sensing, 2015
The present study analyses the new Visible Infrared Imaging Radiometer Suite (VIIRS) lights data to determine whether it can provide more accurate proxies for socioeconomic data in areas with poor quality data than proxies based on stable lights.

JPSS-1 VIIRS Radiometric Characterization and Calibration Based on Pre-Launch Testing

open access: yesRemote Sensing, 2016
The Visible Infrared Imaging Radiometer Suite (VIIRS) on-board the first Joint Polar Satellite System (JPSS) completed its sensor level testing on December 2014. The JPSS-1 (J1) mission is scheduled to launch in December 2016, and will be very similar to

Ten Years of VIIRS EDR Imagery Validation and User Interactions

open access: yesRemote Sensing, 2022
Over ten years of Visible Infrared Imaging Radiometer Suite (VIIRS) Environmental Data Records (EDR) Imagery Team activities have included primarily imagery validation, but also product generation and display and user interactions.

Ice Surface Temperature Retrieval from a Single Satellite Imager Band

open access: yesRemote Sensing, 2018
Current methods for estimating the surface temperature of sea and lake ice—the ice surface temperature (IST)—utilize two satellite imager thermal bands (11 and 12 μm) at moderate spatial resolution.

Satellite‐Based Fishing Fleet Tracking: A New Foundation for Fisheries Science and Management

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Satellite‐based vessel‐tracking technologies have ushered in a new era for monitoring fishing activity at scale. By combining artificial intelligence (AI) methods with remotely‐sensed data, researchers can now detect, classify and analyse fishing behaviour across vast and previously unobservable ocean regions.

Improved Band-to-Band Registration Characterization for VIIRS Reflective Solar Bands Based on Lunar Observations

open access: yesRemote Sensing, 2015
Spectral bands of the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the Suomi National Polar-orbiting Partnership (S-NPP) satellite are spatially co-registered.

A Multi-Band Atmospheric Correction Algorithm for Deriving Water Leaving Reflectances over Turbid Waters from VIIRS Data

open access: yesRemote Sensing, 2023
The current operational multi-band atmospheric correction algorithms implemented by NASA and NOAA for global remote sensing of ocean color from VIIRS (Visible Infrared Imaging Radiometer Suite) data are mostly based on the 2-band version of the SeaWiFS ...

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

open access: yesIbis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

Subnational Border Reforms and Economic Activity in Africa

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT Using GIS methods, we identify territories in Africa affected by subnational border reforms between 1992 and 2013. Descriptive statistics reveal that these territories differed from other African regions across several key dimensions. For example, these territories were more populous and exhibited greater ethnic diversity.

Sea and Freshwater Ice Concentration from VIIRS on Suomi NPP and the Future JPSS Satellites

open access: yesRemote Sensing, 2016
Information on ice is important for shipping, weather forecasting, and climate monitoring. Historically, ice cover has been detected and ice concentration has been measured using relatively low-resolution space-based passive microwave data.
