Abstract

We developed a mobile lidar for the Greenhouse gases Observing SATellite (GOSAT) product validation. This system consists of a small type of Mie lidar and a DIfferential-Absorption Lidar (DIAL). The Mie lidar measures vertical distributions and optical characteristics of aerosols and cirrus clouds at two wavelengths of 1064 nm and 532 nm. The DIAL system observes tropospheric ozone profiles with Raman laser lines at 276.2 nm, 287.2 nm and 299.1 nm which are generated by a Nd : YAG laser and a single Raman cell filled with pressurized CO2 gas. Preliminary observational results are presented with the system.
