Abstract We propose the concept of space-borne synergetic system to measure wind velocity by using the next generation imaging Fourier Transform Spectrometer (imaging FTS) and Doppler lidar. The system consists of imaging FTS technique on Geostationary satellites and Doppler lidar and Doppler cloud profiling radar in polar orbit. Main objectives of the space-borne system are to provide (1) four-dimensional wind with high vertical resolution, (2) four-dimensional water vapor and temperature fields and (3) four-dimensional clouds and aerosols. Simultaneous retrievals of temperature and water vapor will be carried out by the imaging FTS as done by AIRS on Aqua satellite. Atmospheric motion can then be estimated by apply- ing similar technique as AMVs. Observing system that consists of the imaging FTS and Doppler lidar (and/or Doppler cloud radar) will open the new era for improving the numerical weather prediction models and interaction among atmospheric dynamics, water vapor and cloud systems. |
