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).

Towards a Transferable UAV-Based Framework for River Hydromorphological Characterization

Sensors, 2017
The multiple protocols that have been developed to characterize river hydromorphology, partly in response to legislative drivers such as the European Union Water Framework Directive (EU WFD), make the comparison of results obtained in different countries

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 ...

Intercalibration of HRDI and WINDII wind measurements [PDF]

Annales Geophysicae, 1997
The High Resolution Doppler Imager (HRDI) and the Wind Imaging Interferometer (WINDII) in- struments, which are both on the Upper Atmosphere Research Satellite, measure winds by sensing the Doppler shift in atmospheric emission features. Because the

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Drivers of 2024 Record Low Sea Ice in Eastern Hudson Bay: A Satellite Era Perspective

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract By late May 2024, Hudson Bay (HB) reached record‐low sea ice extent (SIE) and sea ice concentration (SIC), which has been attributed to the persistent easterly winds in May 2024. This study further investigates the role of easterly winds as well as broader contributing factors.
