Abstract

The occultation experiment SAGE III (Stratospheric Aerosol and Gas Experiment III) is expected to be launched in Autumn 1999. The instrument will be on board the satellite 'Meteor 3M' on a polar orbit. This experiment is based on the same principle than SAGE II. However some channels are divided in some subchannels. For example it is the case of nitrogen dioxide channel at 430 - 450 nm, ozone at 560 - 624 nm and water vapor at 933 - 960 nm. On the other hand the lunar occultation is added in order to detect minor components: OClO, NO₃. A simulation of the transmissions for only the channel devoted to the water vapor has been done, from a water vapor profile obtained for a SAGE II event. The wavelength range 933 - 960 nm is planned to be divided in thirty subchannels. The inverted profiles of water vapor obtained in each subchannel are compared to the input profile. The relative difference between the mean retrieved profile and the data is smaller than 15%.
