An Investigation of a Novel Cross-Calibration Method of FY-3C/VIRR against NPP/VIIRS in the Dunhuang Test Site

open access: yesRemote Sensing, 2016
Radiometric cross-calibration of Earth observation sensors is an effective approach to evaluate instrument calibration performance, identify and diagnose calibration anomalies, and quantify the consistency of measurements from different sensors.

Uncertainties for Pre- and Post-Launch Radiometric Calibration of Imaging Spectrometers for Multi-Sensor Applications [PDF]

open access: yes
An important aspect to using imaging spectrometer data is the radiometric characterization and calibration of the sensors and validation of their data products and doing so with error budgets with known traceability.

Collective Action Under Repressive Conditions: Integration of Individual, Group, and Structural Level Research, Recommendations, and Reflections

open access: yesSocial Issues and Policy Review, Volume 19, Issue 1, December 2025.
ABSTRACT Social scientific research from different traditions on collective action under repressive conditions is fragmented across different levels of analysis. The current paper takes a first step toward remedying this fragmentation by reviewing research findings on repression and collective action and organizing them into a multilevel framework.

Teacher self‐efficacy: Validating a new measurement scale to capture the elusive construct

open access: yesBritish Educational Research Journal, Volume 51, Issue 5, Page 2229-2255, October 2025.
Abstract Teachers’ beliefs in their ability to positively impact students’ learning outcomes has become a strong indicator of teachers’ motivation and behaviour towards the instructional strategies they employ. However, measuring the broader concept of teacher self‐efficacy is still somewhat problematic as current scales are dated, have measurement ...

SI traceable vicarious calibration test sites and methods.

open access: yes, 2018
Earth Observation via satellite has been successfully used for several decades in many applications. Monitoring climate change is the most challenging one, as it requires highly accurate data to enable detection of small changes in naturally variable signals over different spatial and temporal scales.
