Description
To monitor stratospheric ozone and aerosols, the ALTIUS mission will perform measurements either in limb scattering mode or in occultation mode. In this mode, the satellite will observe the Sun during sunrise and sunset, and the rises and sets of the brightest stars and planets during the night. To increase the geographic coverage of the observations, lunar measurements will also be carried out, when the spacecraft is in the Earth shadow. The variable shape and brightness of the Moon, however, make the simulation and the retrieval works difficult. This poster describes how the lunar mode has been processed in the scene generator created to simulate the ALTIUS observations, as well as how the ALTIUS Moon images will be used to retrieve ozone vertical profiles.
