行星地球高级空间碳和气候观测（A-SCOPE）使命是下一代欧洲空间局地球探索者核心飞行任务的候选者，目的是利用集成路径差分吸收激光雷达从空间测量CO2浓度。我们报告激光雷达仪器工作波长的优化，建立在两个性能模型，以评估测量随机误差的仪器，以及测量处理所需的地球物理和光谱参数的知识错误。一个有前途的方法，以减少1个数量级的水汽误差的灵敏度的报告和说明。所提出的方法适用于任何机载或星载IPDA激光雷达。(C)2009年美国光学学会
The Advanced Space Carbon and Climate Observation of Planet Earth (A-SCOPE) mission, a candidate for the next generation of European Space Agency Earth Explorer Core Missions, aims at measuring CO2 concentration from space with an integrated path differential absorption (IPDA) lidar. We report the optimization of the lidar instrument operating wavelengths, building on two performance models developed to assess measurement random errors from the instrument, as well as knowledge errors on geophysical and spectral parameters required for the measurement processing. A promising approach to decrease sensitivity to water vapor errors by 1 order of magnitude is reported and illustrated. The presented methods are applicable for any airborne or spaceborne IPDA lidar.
