Abstract

The retrieval of aerosol-size distribution from simulated aerosol-extinction-coefficient measurements of the new satellite instrument, the Stratospheric Aerosol and Gas Experiment (SAGE) III, is investigated. A detailed discussion on the aerosol-size-distribution information content of the SAGE III aerosol-extinction-coefficient measurement is provided. Results of the investigation indicate that unimodal as well as bimodal log-normal size distributions can be inferred. In addition, it is shown that a shape-constraint-free size distribution can be derived from SAGE III aerosol measurements by use of the randomized minimization search technique and the optimal estimation theory.

摘要

本文研究了如何从新型卫星仪器平流层气溶胶和气体实验（SAGE）III 的模拟气溶胶消光系数测量结果中反演气溶胶粒径分布。文中详细讨论了 SAGE III 气溶胶消光系数测量中的气溶胶粒径分布信息含量。研究结果表明，可以推断出单峰和双峰对数正态粒径分布。此外，研究表明，利用随机最小化搜索技术和最优估计理论，可以从 SAGE III 气溶胶测量中得出无形状约束的粒径分布。
