Stratospheric Composition Measurements Using Inproved Infrared Remote Sensing Instruments

红外遥感技术通常被用作获取大气痕量组分浓度和高度分布数据的手段。投资促进局建议进行一系列气球飞行，以获得从100厘米-1到3000厘米-1的不同光谱间隔内的高光谱分辨率大气传输和发射数据。传输数据将从地面获得40公里，并在太阳掩星期间从40公里处获得，分辨率为0.002厘米-1(未变迹)。发射数据将在相同的高度范围内以0.04厘米-1的分辨率在肢体观察模式下获得。将对这些数据进行分析，以获得平流层感兴趣化合物的组成概况，其绝对准确度高于以前的研究。该程序中测量的浓度将与先前的数据进行比较，以检测可能的趋势。这些光谱还将与使用最新版本的HITRAN数据库的计算结果进行比较。这些比较对于提高我们准确计算大气辐射传输的能力尤为重要。

Infrared remote sensing techniques are routinely used as a means of obtaining data on the concentration and altitude distribution of atmospheric trace constituents. The PIs propose to conduct a series of balloon flights to obtain high spectral resolution atmospheric transmission and emission data in various spectral intervals from 100 cm-1 to 3000 cm-1. The transmission data will be obtained from the ground through 40 km and from 40 km during solar occultation, at a resolution of 0.002 cm-1 (unapodized). The emission data will be obtained over the same altitude range and in a limb viewing mode at a resolution of .04 cm-1. The data will be analyzed to obtain constituent profiles for compounds of stratospheric interest with higher absolute accuracy than in previous studies. The concentrations measured in this program will be compared with earlier data for detection of possible trends. The spectra will also be compared with calculations using the latest versions of the HITRAN database. These comparisons are particularly important for improving our ability to accurately calculate the atmospheric radiative transfer.
