项目摘要
The investigators will use an airglow imaging instrument to measure atmospheric gravity waves with horizontal wavelengths less than 100 km. They will place a new infrared airglow imager with high sensitivity at the Starfire Optical site in New Mexico. The imager will be used in conjunction with other Starfire instrumentation to investigate the breakdown of gravity waves as well as the momentum flux deposited by acoustic gravity waves, which are believed to be thermally ducted from source regions thousands of kilometers away. The investigators will also analyze airglow imaging data from northern Germany, comparing the results with similar data obtained from Illinois. At the German site, mesopause temperatures can be less than 1250 K, while in Illinois the temperatures are usually greater than 170K. In 1999, the imager will be deployed in Australia for two years, a period of time long enough to allow a better characterization of gravity wave climatology in the southern hemisphere at mid-latitude.
研究人员将使用气辉成像仪测量水平波长小于100公里的大气重力波。他们将在新墨西哥州的星火光学站点放置一台新的高灵敏度红外气辉成像仪。该成像仪将与其他星火仪器一起使用,以调查重力波的破裂以及声波重力波沉积的动量通量,据信这些重力波是从数千公里外的震源区域热导管传来的。调查人员还将分析德国北部的气辉成像数据,将结果与从伊利诺伊州获得的类似数据进行比较。在德国,中层顶温度可以低于1250K,而在伊利诺伊州,温度通常高于170K。1999年,该成像仪将在澳大利亚部署两年,这段时间足以更好地描述中纬度南半球的重力波气候学。
