Retrieval of Atmospheric State variables from GLORIA limb emission spectral images (RASGLO)

该项目的目的是在THEX、POLSTRACC和CIRRUS-RS测量活动期间利用格洛丽亚遥感数据分析控制对流层上部/平流层下部交换的过程。格洛丽亚是一个万向架式临边观测器，安装在HALO飞机的腹部吊舱中，用于基于成像FTIR光谱仪技术对大气进行辐射成像。特殊的仪器模式允许断层摄影测量的中尺度事件在全三维前所未有的空间分辨率和各种各样的大气成分的推导。在该项目的第一个供资期间，开发了用于分析层析成像测量结果的方法和算法以及更先进的云探测方案。在该项目的第二部分（根据此处的要求），将完成温度、水蒸气、CFC-11、PAN、臭氧、SF6、HDO和其他几种物质的反演准备工作，包括对反演不确定性的详细分析。这些物种的2-D和3-D场将来自TALGOR、POLSTRACC和CIRRUS-RS活动期间获得的真实格洛丽亚测量值，然后对检索性能和产品进行详细的质量分析。之后，将对这些数据进行对流层上部和平流层下部混合事件和凝结过程的科学分析。

The aim of this project is to analyze processes controlling upper troposphere / lowermost stratosphere exchange by means of GLORIA remote sensing data during the TACTS, POLSTRACC and CIRRUS-RS measurement campaigns. GLORIA is a gimballed limb observer for radiance imaging of the atmosphere based on imaging FTIR spectrometer technology, mounted in the belly pod of the HALO aircraft. Special instrument modes allow for tomographic measurements of mesoscale events in full 3-D with unprecedented spatial resolution and the derivation of a wide variety of atmospheric constituents. In the first funding period of this project, methods and algorithms for the analysis of tomographic measurements as well as more advanced cloud detection schemes were developed. In the second part of the project (as requested here), preparatory work for the retrieval of temperature, water vapor, CFC-11, PAN, ozone, SF6, HDO, and several other species will be completed, including a detailed analysis of retrieval uncertainties. 2-D and 3-D fields of these species will be derived from real GLORIA measurements obtained during the TACTS, POLSTRACC, and CIRRUS-RS campaigns, followed by detailed quality analysis of the retrieval performance and the products. After that, scientific analyses of this data with respect to mixing events and condensational processes in the upper troposphere and lowermost stratosphere will be performed.
