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.

大气层的傅里叶变换红外光谱已被确定为获取有关大气层的组成、动力学和化学信息的一种有价值的、通用的工具。FTIR光谱的独特之处在于，它记录了宽带但高分辨率的光谱，其中包含关于许多不同痕量气体的丰富信息。虽然FTIR仪器已被开发成达到非常高的分辨率和高信噪比(SNR)，但正演模拟使用了目前不足以模拟FTIR光谱记录的大气光谱的光谱假设和参数(例如谱线强度)。这里提出的工作试图缩小有关重要大气气体，即H2O和CH4光谱的最新理论知识的技术和实施之间的差距。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结果的即时测试相结合，包括及时向实验室小组反馈的做法。
