根据天文数据计算的大气O2
Atmospheric O2 from astronomical data
摘要：
尽管许多人试图找到大气气体含量与气候变化之间的关系，但旨在监测和预测O2消耗的环境研究仍然缺乏或需要改进。本项目的目的是通过使用恒星光谱中存在的大地线来确定大气O2耗尽的准确历史序列。如果对不同的气团、不同的季节、不同的地点进行高分辨率的光谱观测，如果逐年监测变化，就有可能更好地了解氧在大气热平衡中的作用。天文光谱技术主要涉及高分辨率恒星光谱中吸收特征的研究，但我们也在考虑是否可以从中低分辨率恒星光谱中获得大气O2丰度的精确测量。
英文摘要：
Environmental research aimed at monitoring and predicting O2 depletion is still lacking or in need of improvement, in spite of many attempts to find a relation between atmospheric gas content and climate variability. The aim of the present project is to determine accurate historical sequences of the atmospheric O2 depletion by using the telluric lines present in stellar spectra. A better understanding of the role of oxygen in atmospheric thermal equilibrium may become possible if high-resolution spectroscopic observations are carried out for different airmasses, in different seasons, for different places, and if variations are monitored year by year. The astronomical spectroscopic technique involves mainly the investigation of the absorption features in high-resolution stellar spectra, but we are also considering whether accurate measures of the atmospheric O2 abundances can be obtained from medium and low resolution stellar spectra.
