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

Remote 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.

GOCI의 육상활용을 위한 Vicarious calibration 기법연구

, 2012
이 연구는 GOCI영상의 육살활용을 위한 vicarious calibration에 대한 것이다. GOCI의 spectral setting은 해색 관측을 위해 설계되었지만 band 3, band 4, band 5, band 8은 육상관측에도 적합하다. Vicarious calibration을 수행하기 위해서는 높은 반사도와 공간적 균일성을 갖는 calibratition 타겟을 찾아야 한다.
