Imaging Science Investigations of Upper Atmospheric Processes

更新一项为期3年的授权，用于运行雪松光学层析成像设备（COTIF），并对所获得的结果进行科学分析，其中COTIF能力将应用于与稳定红色极光（SAR）弧源相关的亚极光物理的几个方面。现在太阳活动极大期即将来临，1998年底SAR弧的重新出现为研究SAR弧的体积发射率的纬度高度依赖性提供了第一次机会，这是获得高度依赖性激发物理的唯一可能方法。热激发、高速对流激发和质子沉淀增强发射的问题现在可以解决了。为了进行后一项研究，PI建议使用CEDAR资助的高通量成像埃舍尔光谱仪（HITIES）。SAR电弧机制的建模专业知识已经到位，质子建模的主要专家将作为另一个项目的一部分加入该小组。这项工作的新成果是将COTIF和HITIES的成像科学能力应用于中间层重力波的研究。一个雪松博士后奖给史蒂文·史密斯博士将允许研究这些数据集的波源和耗散机制。随着新的FPI和LIDAR仪器在Millstone Hill安装，一套真正强大的光学诊断将最终到位，用于亚极光站点波活动的首次全面研究。更新一项为期3年的授权，用于运行雪松光学层析成像设备（COTIF），并对所获得的结果进行科学分析，其中COTIF能力将应用于与稳定红色极光（SAR）弧源相关的亚极光物理的几个方面。现在太阳活动极大期即将来临，1998年底SAR弧的重新出现为研究SAR弧的体积发射率的纬度高度依赖性提供了第一次机会，这是获得高度依赖性激发物理的唯一可能方法。热激发、高速对流激发和质子沉淀增强发射的问题现在可以解决了。为了进行后一项研究，PI建议使用CEDAR资助的高通量成像埃舍尔光谱仪（HITIES）。SAR电弧机制的建模专业知识已经到位，质子建模的主要专家将作为另一个项目的一部分加入该小组。这项工作的新成果是将COTIF和HITIES的成像科学能力应用于中间层重力波的研究。一个雪松博士后奖给史蒂文·史密斯博士将允许研究这些数据集的波源和耗散机制。随着新的FPI和LIDAR仪器在Millstone Hill安装，一套真正强大的光学诊断将最终到位，用于亚极光站点波活动的首次全面研究。

ATM-0071836Mendillo, MichaelA renewal of a 3-year grant to operate the CEDAR Optical Tomographic Imaging Facility (COTIF) and for the scientific analysis of the results obtained is proposed in which COTIF capabilities will be applied to several aspects of sub-auroral physics related to sources of stable red auroral (SAR) arcs. Now that solar maximum is approaching, the re-appearance of SAR arcs in late 1998 offers the first ever opportunity to study the latitude-altitude dependence of volume emission rates for SAR arcs, the only possible way to access the height-dependent excitation physics. Issues of thermal excitation, high speed convection excitation, and augmentation of emission by proton precipitation can now be addressed. To conduct the latter study, the PI proposes to field a CEDAR funded high-throughput-imaging-Eschell-spectrograph (HITIES). Modeling expertise for SAR arc mechanisms is in place, and a leading expert on proton modeling will join the group as part of another program.New to this effort is the application of imaging science capabilities from COTIF and HITIES to the study of mesospheric gravity waves. A CEDAR Post-doctoral award to Dr. Steven Smith will allow for the study of wave sources and dissipation mechanisms from these datasets. With new FPI and LIDAR instruments being installed at Millstone Hill for the CEDAR-TIMED collaboration, a truly robust set of optical diagnostics will finally be in place for the first comprehensive study of wave activity at a sub-auroral site.
