High Resolution Infrared (IR) Stratospheric Spectral Atlas and Laboratory Studies

这项研究将扩展丹佛大学的高分辨率(约0.002厘米-1)气球载红外太阳吸收平流层光谱图集，以及以前美国国家科学基金会拨款启动的相应实验室、地面和理论研究。主要目标是：1)利用已经获得的太阳光谱和实验室光谱以及预计将在2005年至2008年获得的新光谱，将0.002厘米-1分辨率的地图集扩展到2.5-30微米范围内。许多新的平流层光谱特征将被观测和研究。2)扩大对平流层特定分子的光谱分析，如来自实验室的O_3、HNO_3、ClONO_2、COF_2、CO_2、HCOOH、NO、O_2、O_2、OH、NO等，以及平流层光谱。光谱分析将包括用于鉴定和量化痕量物种的谱线位置和谱线强度。这项理论光谱学的工作促进了分子和原子结构模拟的新方法的发展，导致了能够更准确地测量大气的新仪器技术的结合。这些研究还继续对行星和天体物理光谱以及环境光谱的理解产生更广泛的影响。

This research will extend the University of Denver atlas of high resolution (~0.002 cm-1) balloon-borne infrared solar absorption stratospheric spectra and the corresponding laboratory, ground-based and theoretical studies initiated under previous NSF grants. The major objectives are: 1) To extend the 0.002 cm-1 resolution atlases over additional intervals in the 2.5-30 micron region, by using solar and laboratory spectra already obtained and new spectra anticipated to be obtained in 2005-2008. Many new stratospheric spectral features will be observed and studied. 2) To extend the spectroscopic analysis of specific stratospheric molecules, such as O3, HNO3, ClONO2, COF2, COCl2, HCOOH, NO2, O2, OH, NO and others, from the laboratory and stratospheric spectra. The spectroscopic analysis will include line positions and line intensities for identification and quantification of trace species. Contributions are expected to the field of atmospheric chemistry through atmospheric and solar spectroscopy.This work on theoretical spectroscopy promotes the development of new methods for modeling molecular and atomic structure, leading to the incorporation of new technologies for instrumentation capable of more accurate atmospheric measurements. These studies also continue to have broader impacts on the understanding of planetary and astrophysical spectroscopy, as well as environmental spectroscopy.
