ASTER calibration concept

Calibration concept of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) for EOS-A platform is presented. Emphasis is placed on the instrument characteristics to be used for quantitative data analysis which include response linearity, spectral profile of responsivity, polarization characteristics, size-of-source effect, element-to-element responsivity ratio, band-to-band responsivity ratio, and absolute spectral band responsivity. Attention is also given to prelaunch and in-flight calibration for visible infrared, short-wave infrared, and thermal infrared subsystems and a new scheme for cross calibration of ASTER.
