Simplified Vicarious Radiometric Calibration [PDF]

, 2010
A measurement-based radiance estimation approach for vicarious radiometric calibration of spaceborne multispectral remote sensing systems has been developed. This simplified process eliminates the use of radiative transfer codes and reduces the number of

The Specular Array Radiometric Calibration (SPARC) Technique As A Vicarious Methodology For Accurate Inter-Sensor Calibration [PDF]

, 2012
Current in-flight inter-sensor vicarious calibration methods either rely on extended stable instrumented calibration sites that allows prediction of at-sensor radiance at the time of the image collect or with pseudo-invariant sites that allow transfer of

System vicarious calibration and ocean color retrieval from the HY-1C UVI

International Journal of Applied Earth Observations and Geoinformation
Ultraviolet (UV) remote sensing plays a critical role in understanding photochemical and biological processes in the global ocean. While UV radiation significantly influences the marine environment, the limited availability of global UV measurements has ...

SI traceable vicarious calibration test sites and methods.

, 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.

ABSTRACT RADIATIVE TRANSFER CODE COMPARISON FOR MERIS VICARIOUS CALIBRATION

, 2008
Different groups are involved in the MERIS vicarious activities. Most of the time, the prediction of the incoming radiance to the sensor needs radiative transfer computations.

Vicarious Liability

, 1954
Under the fault principle as we know it today there are many situation in which A is held liable to C for damages which B's negligence has caused C, even though A has been free from negligence or other fault.
