CRDS absorption spectra recorded for the P(16) and P(28) transitions of the 20012-00001 band, and the R(24) and R(30) transitions of the 20013-00001 band of 12CO2 in air

The database is made of the set of the CRDS absorption spectra recorded for the P(16) and P(28) transitions of the 20012-00001 band, and the R(24) and R(30) transitions of the 20013-00001 band of 12CO2 in air, following the procedures and with the experimental setups described in the paper entitled "Line shape parameters of air-broadened 12CO2 transitions in the 2.0 µm region, with their temperature dependence" by D. Mondelain, A. Campargue, H. Fleurbaey, S. Kassi, S. Vasilchenko published in JQSRT 298 (2023) 108485. <br> Each averaged spectrum corresponds to a .csv file including the following columns: <br> absolute wavenumber (in cm-1), cavity loss rate 1/ct (in 10-6 cm-1), temperature (in °C) and total pressure (in Torr). Two gas mixtures of CO2 in air (Ar : ~1 Mol-% ; O2 :~20.95 Mol-% ; N2 : ~78.05 Mol-%) are used in this work. <br> The stated sample CO2 mixing ratios are 6.013±0.060 Mol-ppm for the 20012-00001 band and 40.10±0.24 Mol-ppm for the 20013-00001 band.本数据库收录了空气中¹²CO₂的20012-00001谱带P(16)、P(28)跃迁，以及20013-00001谱带R(24)、R(30)跃迁对应的腔环衰荡吸收光谱（Cavity Ring-Down Spectroscopy, CRDS）数据集，所有光谱数据均遵循D. Mondelain、A. Campargue、H. Fleurbaey、S. Kassi、S. Vasilchenko发表于《Journal of Quantitative Spectroscopy & Radiative Transfer》（简称JQSRT）2023年第298卷第108485号的论文《2.0 μm波段空气展宽¹²CO₂跃迁的线型参数及其温度依赖性》中所述的实验流程与装置完成采集。 每条平均光谱均对应一个.csv格式文件，文件包含以下列数据：绝对波数（单位：cm⁻¹）、腔损耗率1/ct（单位：10⁻⁶ cm⁻¹）、温度（单位：℃）以及总压强（单位：托（Torr））。 本研究使用两种CO₂-空气混合气体体系，混合气体的空气组分摩尔占比为：氩气（Ar）约1 mol%、氧气（O₂）约20.95 mol%、氮气（N₂）约78.05 mol%。 其中，用于20012-00001谱带数据采集的CO₂摩尔分数为6.013±0.060 mol-ppm，用于20013-00001谱带数据采集的CO₂摩尔分数为40.10±0.24 mol-ppm。
