Abstract

This paper describes the results of on-orbit center wavelength calibration of twenty MODIS Solar Reflective Bands (SRB) by the SRCA. The calibration signal problems and the uncertainty estimates are described. The calibration results show that (1) SRCA monochromator parameters are stable; (2) MODIS band center wavelengths measured have less than 0.4 nm change from prelaunch to on-orbit; and (3) MODIS band response profile changes slightly for band 8 and remains unchanged for the other measured SRBs
