Mapping global winds with satellite borne Doppler lidar - A plan

The application of the Laser Atmospheric Wind Sounder to the EOS and Space Station is proposed. The use of pulsed, CO2 Doppler lidar to measure wind is described. The design requirements for a Doppler lidar operating in space, and the need to study the global distribution of naturally occurring atmospheric aerosols are discussed. The space-based Doppler lidar wind data will be useful for improving the skill of numerical weather predictions, for studying large-scale atmospheric circulation and climate dynamics, and for analyzing global biogeochemical and hydrological cycles.
