米国Rogers Dry Lake におけるAVNIR・OCTS補正係数の相互検証

抄録

The cross validation and the in-flight calibration are carried out for the radiometric calibration of AVNIR and OCTS reflective bands at the Rogers (Dry) Lake in USA. These two sensors are on the same platform, ADEOS, and can acquire the image of same scene in same sun-target-sensor geometry simultaneously, therefore the calibration coefficients in the cross calibration can be obtained with small uncertainty. The OCTS calibration coefficients in in-flight calibration based on the vicarious calibration and the cross calibration show the difference of 10 to 20% from the previously reported ones, and the AVNIR and OCTS calibration coefficients in cross validation based on the cross calibration show the difference of 10%.
