摘要

For the post-2000 time-frame two general classes for Earth Observation missions have been identified to address user requirements (see e.g. ESA, 1995), namely Earth Watch and Earth Explorer missions. One of the candidate Earth Explorer MIssions selected for Phase A study is the Atmospheric Dynamics Mission which is intended to exploit a Doppler wind lidar, ALADIN, to measure winds in clear air (ESA, 1995 and ESA, 1996). It is being studied as a candidate for flight on the International Space Station (ISS) as an externally attached alyoad. The primary, long-term ogbjective of the Atmospheric Dyamics Mission is to provide observations of wind profiles (e.g. radial wind component). Such data would be assimilated into numerial forecasting models leading to an improvement in objective analyese and hence in assimilated into numerical forecasting models leading to an improvement in objective analyses and hence in NUmerical Weather Prediction. The mission would also provide data needed to address some of the key concerns of the World Climate Research Programme (WCRP) i.e. quantification of climate variability, validation and improvement of numerical models and process studies relvant to climate change. The newly acquired data wouold also hepl relaise some of the objectives of the Global Climate Observing System (GCOS).
