Introduction of water-vapor broadening coefficients and their temperature dependence exponents into the HITRAN database, Part I: CO2, N2O, CO, CH4, O2, NH3, and H2S
摘要：
陆地大气中的水汽含量在空间和时间上都是高度可变的。在热带地区，它有时占大气的4-5%。同时，水蒸气对谱线的碰撞增宽比氮气和氧气对谱线的碰撞增宽大得多。因此，为了准确地表征和模拟具有大量水蒸气的大气的光谱，需要用于被水蒸气加宽的谱线的线形参数。在这项工作中，线加宽系数（和它们的温度依赖指数）由于水蒸气的压力为CO2，N2 O，CO，CH 4，O2，NH3，和H2S线的实验和理论研究收集和仔细审查。基于这些收集的数据创建了一组半经验模型，然后用于估计HITRAN 2016数据库中选定分子的所有跃迁的水增宽及其温度依赖性。
英文摘要：
The amount of water vapor in the terrestrial atmosphere is highly variable both spatially and temporally. In the tropics it sometimes constitutes 4-5% of the atmosphere. At the same time collisional broadening of spectral lines by water vapor is much larger than that by nitrogen and oxygen. Therefore, in order to accurately characterize and model spectra of the atmospheres with significant amounts of water vapor, the line-shape parameters for spectral lines broadened by water vapor are required. In this work, the line-broadening coefficients (and their temperature dependence exponents) due to the pressure of water vapor for lines of CO2, N2O, CO, CH4, O2, NH3, and H2S from both experimental and theoretical studies were collected and carefully reviewed. A set of semi-empirical models based on these collected data was created and then used to estimate water broadening and its temperature dependence for all transitions of selected molecules in the HITRAN2016 database.
