ATM9813825absThe investigators will continue using a Fabry-Perot interferometer for systematic studies of variability of faint exospheric hydrogen Balmer-alpha emission intensity due to solar and other natural influences. The instrument is called WHAM for Wisconsin H-Alpha Mapper, and is located at the Kitt Peak Observatory in Tucson, Arizona. The sun plays a major role in defining the base properties of the upper atmosphere. Its influence through heating and photochemistry must be understood to accurately characterize the upper atmosphere and to separate natural from possible anthropogenic signatures in this region. The observations made with WHAM will lead to improved understanding of natural variability in upper and middle atmospheric hydrogenous species, thereby facilitating more detailed predictions for their response to anthropogenic increases in greenhouse gases.

ATM9813825Abb研究人员将继续使用法布里-珀罗涉仪，系统地研究由于太阳和其他自然影响而产生的微弱的外层氢气巴尔默-阿尔法发射强度的变化。这台仪器被称为威斯康星州H-Alpha映射器的WHAM，位于亚利桑那州图森市的基特峰天文台。太阳在定义高层大气的基本属性方面起着重要作用。必须了解其通过加热和光化学产生的影响，以准确地描述高层大气的特征，并区分该区域的自然和可能的人为特征。与世界气象组织进行的观测将有助于更好地了解上层和中层大气含氢物种的自然变异性，从而有助于更详细地预测它们对温室气体人为增加的反应。
