This project will lead to the development of a technique for measuring the composition of the neutral atmosphere. A high resolution spectrometer will be used to measure optical emissions produced by atmospheric species. By combining these measurements with theoretical models, it is possible to determine neutral densities and temperatures and a scaling factor for the solar extreme ultraviolet flux. The spectrometer will measure emissions between 560 and 740 nanometers. The instrument will provide the first measurements from the ground of several important emissions produced in the mesosphere and thermosphere.

这个项目将导致一种测量中性大气成分的技术的发展。一台高分辨率光谱仪将用于测量大气物质产生的光发射。通过将这些测量与理论模型相结合，可以确定中性密度和温度以及太阳极紫外线通量的比例因子。光谱仪将测量560到740纳米之间的辐射。该仪器将首次从地面对中间层和热层产生的几种重要排放物进行测量。
