2007年1月在赤道站点Tirunelveli(北纬8.7N，东经77.8E；磁倾角1.34N)安装了一台全天气辉成像仪，以研究中间层低热层(MLT)区域发生的小尺度动力学。文中给出了仪器的详细信息，以及从记录数据中检索信息的方法。用该仪器观测到的各种小规模中层动力事件的存在被证明是存在的。关于观察到的特征的初步结果，即。本文介绍了准单色重力波和波纹、中间层孔等不稳定特征。
An all-sky airglow imager was installed at the equatorial site Tirunelveli (8.7N, 77.8E geographic; 1.34N magnetic dip) during January 2007 to study the small-scale dynamics occurring in the mesosphere-lower thermosphere (MLT) region. The instrument details are presented in the paper along with methods of information retrieval from the recorded data. The presence of a variety of small-scale mesospheric dynamical events, observed with the instrument, is demonstrated. Preliminary results on the observed features, viz. the quasi-monochromatic gravity waves and instability features, such as ripples and mesospheric bores, are presented in the paper.
