Building consistent time series night-time light data from average DMSP/OLS images for indicating human activities in a large-scale oceanic area

International Journal of Applied Earth Observations and Geoinformation, 2022
Human activities in the ocean have never been chronically and continuously investigated on a large scale. Night-time light (NTL) images collected by the Defense Meteorological Satellite Program/Operational Linescan System (DMSP/OLS) have been used as a ...

Empirical Polarization Distribution Models for Use in CLARREO Pathfinder-VIIRS Intercalibration

Remote Sensing
In this work, we discuss the impact of polarized scene radiances on the intercalibration of CPF and VIIRS reflective solar bands and the mitigation of these effects using empirical Polarization Distribution Models (ePDMs).

Intercomparisons of Nine Sky Brightness Detectors

Sensors, 2011
Nine Sky Quality Meters (SQMs) have been intercompared during a night time measurement campaign held in the Netherlands in April 2011. Since then the nine SQMs have been distributed across the Netherlands and form the Dutch network for monitoring night ...

Current and Future Changes in Earth's Outgoing Infrared Spectrum

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Hyperspectral infrared satellite observations provide an information‐rich, global record of climate mean state and change without the structural uncertainties often present satellite retrievals and reanalyses. Current and planned hyperspectral satellite missions will continuously observe changes in Earth's outgoing infrared spectrum into the ...

Radiometric Evaluation of SNPP VIIRS Band M11 via Sub-Kilometer Intercomparison with Aqua MODIS Band 7 over Snowy Scenes

Remote Sensing, 2018
A refined intersensor comparison study is carried out to evaluate the radiometric stability of the 2257 nm channel (M11) of the first Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the Suomi National Polar-orbiting Partnership (SNPP) satellite.

3D definition of the river bankfull stage from topographic LiDAR

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
A 3D definition of river bankfull stage based on hydraulic depth derived from high‐density topographic LiDAR is proposed and implemented through the Bf3D framework, applied at the reach scale across 28 French rivers. Extending analysis beyond individual cross‐sections opens new opportunities for large‐scale, automated hydromorphological monitoring ...

Changes in size‐at‐age of juvenile Atlantic salmon cohorts over the past 50 years and linkages to environmental factors

Journal of Fish Biology, Volume 108, Issue 5, Page 1524-1550, May 2026.
Abstract Quantifying the potential effects of climate change on juvenile salmonid body length at a large spatiotemporal scale is challenging given the multitude of biological processes and methodological constraints. In the present work, we analysed potential changes in size‐at‐age of juvenile Atlantic salmon cohorts over the past 50 years in the ...
