Improving spectroscopic data of H2O in the mid infrared for application on high resolution spectroscopy of the atmosphere..

大气的傅里叶变换红外光谱已被确立为一种宝贵且通用的工具，可用于获取有关大气成分、动力学和化学的信息。FTIR光谱学在这个意义上是独特的，它记录了宽带但高度分辨的光谱，其中包含了许多不同痕量气体的丰富信息。虽然傅里叶变换红外光谱仪的开发已达到非常高的分辨率和高信噪比，但正演建模使用的光谱假设和参数（如谱线强度）目前还不够准确，无法对傅里叶变换红外光谱仪记录的大气光谱进行建模。这里提出的工作试图缩小技术和实施有关重要大气气体（即H2O和CH4）光谱学的最新理论知识之间的差距。目前尚不存在将最先进的实验室测量与大气研究小组对所获得的结果进行即时测试，包括及时向实验室小组提供反馈相结合的情况。

The FTIR spectroscopy of the atmosphere has been established as a valuable and versatile tool to draw information about the composition, the dynamics and chemistry of the atmosphere. The FTIR spectroscopy is unique in the sense, that it records broadband yet highly resolved spectra which contain a wealth of information about many different trace gases. While the FTIR instruments have been developed to reach very high resolution and a high signal to noise ratio (SNR), the forward modeling uses spectroscopic assumptions and parameters (e.g. line strengths) which are currently not accurate enough to model atmospheric spectra recorded by FTIR spectroscopy. The work proposed here attempts to close this gap between technology and implementation of latest theoretical knowledge about the spectroscopy of important atmospheric gases, i.e. H2O and CH4. The combination of state-of-the-art laboratory measurements and the immediate testing of the obtained results by atmospheric research groups including an timely feed-back to the laboratory group does not yet exist.
