Investigators Gary Swenson and Chester Gardner developed a model relationship for the hydroxyl radical Meinel band airglow, focusing on the intensity or rotational temperature changes and changes due to atmospheric wave perturbed density/temperature. Now, they extend validating this model to use data from two facilities. They are also using the same relationship of intensity to the 5577 angstrom emission from atomic oxygen and the oxygen molecule atmospheric band airglow. Finally, they are developing spectral models of airglow images to study MesoD campaign data from Illinois, and will upgrade and field an airglow imager at Albuquerque, associated with a Starfire follow-on campaign. An added benefit to this project is its investment to planned investigations with the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite mission.

研究人员加里斯文森和切斯特加德纳开发了一个模型的羟基自由基Meinel带气辉的关系，侧重于强度或旋转温度的变化和变化，由于大气波扰动密度/温度。 现在，他们扩展了验证这个模型，使用来自两个设施的数据。 他们还使用了相同的强度关系，以5577埃发射原子氧和氧分子大气带气辉。 最后，他们正在开发气辉图像的光谱模型，以研究来自伊利诺伊州的MesoD活动数据，并将升级和现场的阿尔伯克基的气辉成像仪，与星火后续活动。 该项目的另一个好处是，它对计划中的利用热层、电离层、中间层、能量学和动力学（TIMED）卫星使命进行的调查进行了投资。
