Abstract

The space borne remote sensing imaging spectrometer MOS will be launched to the Russian MIR-station in autumn 1995. It was developed for monitoring large scaled effects of the oceans, the atmosphere and land such as chlorophyll content, yellow substances, sediments, aerosol parameters, vegetation stress, and vegetation index. Information about such state parameters will be derived from the spectral function of the backscattered sun radiation of the objects under investigation. This spectral function will be measured in 13 wavelength channels from 408 nm to 1010 nm with 10 nm halfwidth for ocean, land, and atmospheric purposes and in 4 channels at the O₂-A-absorption band from 757 nm to 767 nm with 1.4 nm half width for atmospheric purposes only. The reliability of the thematic interpretation depends strongly on the accuracy of the measured data, and it depends on the on-ground and the in-flight calibration methods and procedures. The determination of the spectral sensitivity function of each sensor element, their shape as well as the absolute values on ground and the check of the stability of the scanner properties during the mission time are described.
