ANLC-93: Aircraft-Borne and Ground-Based Hydroxyl and NLC Measurements of Small and Large-Scale Dynamics in the Polar Summer Mesosphere

作为93年北极夜光云运动的一部分， 建议使机载和地基分光 羟基红外夜光的观测以及 NLC的照片。 这些将被完成， 研究剩余重力场和行星波场 在北极夏季，它们可能与 中层云的形成。 目的是测量OH NCAR飞机的夜光辐射和温度。 这 将在NLC和PMC中描述中间层的特征 并研究中间层云层之间的关系 飞机激光雷达探测到的地理特征 OH重力波和行星尺度扰动的影响。 下一个是 PI建议描述极地夏季中间层的特征 在整个战役中， 辐射和温度的地面站位于约 60oN。 这些测量将用于检查时间 重力波和行星尺度扰动的行为， 提供飞行器数据可以被 翻译。 最后，NLC的存在将在很大程度上 记录在地面站，以确定 发生频率、范围、海拔高度和结构， NLC的形态。

As part of the Arctic Noctilucent Cloud Campaign-93, the PIs propose to make aircraft-borne and ground-based spectroscopic observations of the hydroxyl infrared nightglow as well as photographic observations of NLC. These will be done to investigate the residual gravity and planetary wave fields present during the Arctic summer and their possible relationship to the formation of mesospheric clouds. The intent is to measure the OH nightglow radiance and temperature from the NCAR aircraft. This will be done both to characterize the mesosphere in the NLC and PMC regions and to examine the relationship of the mesospheric clouds detected by the aircraft Lidar to the geographical characteristics of the OH gravity waves and planetary-scale disturbances. Next, the PIs propose to characterize the polar summer mesosphere throughout the campaign with observations of the OH nightglow radiance and temperature from ground stations located at about 60oN. These measurements will be used to examine the temporal behavior of gravity waves and planetary scale disturbances and will provide the context within which the aircraft data may be interpreted. Finally, the presence of NLC will be photographically documented over the ground stations in order to determine the occurrence frequency, extent, altitude and the structure and morphology of the NLC.
