Vicarious Calibration of Satellite Ocean Color Sensors at Two Coastal Sites

, 2010
Regionally specific vicarious calibration coefficients for ocean color sensors have been computed for the visible bands using the normalized water leaving radiance L_wn collected at sites in the northern Adriatic Sea and Baltic Proper. These coefficients

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

, 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
