The proposed research work is focused on the retrieval of information about the state of the atmosphere. In particular, we develop techniques to measure the global distribution of ozone at unprecedented spatial resolution. We do this through analysis of optical measurements from satellite platforms. There are two equally important aspects to this work. Firstly, tools must be developed to accurately calculate the transmission of radiation through the atmosphere. Secondly, algorithms must be developed to extract atmospheric profiles that best fit the observed optical signal. These retrieval algorithms adjust the state of the atmosphere until there is good agreement between the simulated and measured signals.

提出的研究工作的重点是检索有关大气状况的信息。特别是，我们开发了以前所未有的空间分辨率测量臭氧全球分布的技术。我们通过分析卫星平台上的光学测量结果来做到这一点。这项工作有两个同样重要的方面。首先，必须开发工具来精确计算通过大气的辐射传输。其次，必须开发算法来提取最适合观测到的光信号的大气剖面。这些检索算法调整大气状态，直到模拟和测量信号之间有很好的一致性。
