Calibration and use of an ultra-portable field transfer radiometer for automated vicarious calibration [PDF]

Earth Observing Systems XXII, 2017
A small portable transfer radiometer has been developed as part of an effort to ensure the quality of upwelling radiance at automated test sites used for vicarious calibration in the solar reflective. The test sites, such as the one located at Railroad Valley, are used to predict top-of-atmosphere reflectance relying on ground-based measurements of the

Trajectories and Adaptive Recalibration of Self-Efficacy in Brazilian Medical Students: A Longitudinal Study With Implications for Educational Support. [PDF]

Clin Teach
ABSTRACT Introduction Self‐efficacy, the belief in one's capacity to execute actions necessary to achieve specific objectives, is a significant predictor of academic performance and well‐being in medical training. Longitudinal studies examining the dynamic evolution of self‐efficacy throughout undergraduate medical education remain scarce in the ...
