Abstract We have proposed a synergy space-borne observation mission using lidar and 94 GHz Doppler cloud radar. The main purposes of this earth observation mission are to understand the interaction processes on aerosols, clouds, convection, radiation, and precipitation comprehensively; to improve cloud reproducibil- ity and cloud-precipitation processes in climate change prediction model; and to contribute to reducing uncertainty in climate change prediction. Expexted products include: (1) microphysics of clouds, aerosols and precipitations, (2) fall velocity of clouds, rain and snow particles, and (3) air motion in cloud, above clouds and in clear sky condition. To achive the purposes, development of a high spectral resolution lidar (HSRL) with doppler, multi-filed-of-view, and depolarization measurement functions is underway. In this article, we report the outline of this proposed mission and the current status of development studies on the space-borne HSRL. In addition, space lidar missions related to aerosol and cloud measurements studied at home and abroad are reported. |
