Quality Scoring of the Fengyun 4A Clear Sky Radiance Product
Remote Sensing, 2021 The Clear Sky Radiance (CSR) product has been widely used instead of Level 1 (L1) geostationary imager data in data assimilation for numerical weather prediction due to its many advantages concerning superobservation methodology.

Radiometric calibration using photo collections [PDF]
2011 IEEE International Conference on Computational Photography (ICCP), 2011 Access to the scene irradiance is a desirable feature in many computer vision algorithms. Applications like BRDF estimation, relighting or augmented reality need measurements of the object's photometric properties and the simplest method to get them is using a camera.

Synthetic Aperture Radar Radiometric Cross Calibration Based on Distributed Targets
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Synthetic aperture radar (SAR) radiometric calibration is an essential step in inferring meaningful physical information about the target. The majority of current calibration processes are directly based on artificial calibrators, but the number of ...

Once is enough in radiometric calibrations
Journal of Research of the National Institute of Standards and Technology, 2007 The successful development of an Optical Technology Division quality system for optical radiation measurement services has provided the opportunity to reconsider the existing calibration procedures to improve quality and reduce costs. We have instituted procedures in our calibration programs to eliminate uninformative repetitive measurements by ...
