The atmosphere at mesospheric and lower thermospheric levels (80 to 120 km altitude) is continually subject to the disturbance of waves passing through the region, including diurnal and semidiurnal tides, planetary waves, and gravity waves originating at tropospheric levels which propagate upward with exponentially increasing amplitude, as the atmospheric density exponentially decreases with height. The wave activity affects the chemical reactions producing airglow in several layers in the region, and it is possible to study the wave properties (wavelength, direction of propagation, amplitude, etc.) and sometimes infer sources, by ground based observations of the airglow emissions at night using photometers and allsky imaging cameras. This award is to initiate a program of such observations at an undergraduate institution, in cooperation with researchers at other institutions using complementary radio and optical equipment. The training of undergraduate students in atmospheric science, and the arousal of their interest in a possible research career, are added benefits of the activity.

中层和低热层大气 (80到120公里的高度）持续受到扰动 通过该地区的波浪，包括昼夜和 半日潮、行星波和重力波 起源于对流层，向上传播， 随着大气密度的增加， 随高度呈指数下降。 波浪活动影响着 化学反应在大气中的几个层中产生气辉， 区域，并有可能研究波的性质 （波长、传播方向、振幅等）和 有时推断来源，通过地面观测的 用光度计和全天空成象法测定夜间气辉发射 相机 这个奖项是为了启动一个计划， 在本科院校的观察，在合作与 其他机构的研究人员使用补充无线电， 光学设备 本科生的培养 大气科学，以及唤醒他们对大气科学的兴趣， 可能的研究生涯，是活动的额外好处。
