[Total Budget for FY1991-1994]

34,206,000 Yen (FY1994 8,396,000 Yen)

[Abstract]

The present study aims at defining objectives of satellite-borne lidar(laser radar) measurements of the global atmosphere and establishing the specifications of a lidar system to be developed in the near future. To do this, numerical simulation studies, investigations on data utilization, and surveys on elemental technique feasibility were carried out from FY1991 to 1993. In FY1994, lidar specifications for a small-sized satellite, which might be launched by a J-1 rocket, was defined on the basis of these previous studies.
It was shown that a lidar system for a small-sized satellite could be developed with power consumption of 150W and mass of 150kg, and which could be applied to global observations of clouds and stratospheric dense aerosols after major volcanic eruptions.
