Simulation and impact study of future spaceborne Doppler wind lidar in Japan
The ISOSIM-L simulates backscattered power, background noise power, signal-to-noise ratio, wind speed and direction and their accuracy. Quasi-truth atmospheric field, which is an input of ISOSIM-L, is generated based on the Sensitivity Observing System Experiment (SOSE) approach. Aerosol consistent with quasi-truth wind is provided by the global aerosol model of MRI. Simulated line-of-sight wind speeds are assimilated with the four-dimensional variational (4D-Var) scheme based on the global operational assimilation system at JMA.
The preliminary results will be presented at the meeting.
