Doppler lidar on the space station

A study was finished in 1994 to identify a payload package for the originally planned Russian MIR-2 station. Part of this study now can be used for an ALADIN type of instrument. Installation on a Russian module of the International Space Station Alpha gives no problems with solar panels. The 8-step version of the Daimler Benz group can be realized. Footprint structure is analyzed for a pre-operational use of the data. Additional information on the backscatter mode of an ALADIN is given.
