Imaging Science Investigations of Upper Atmospheric Processes

建议延长一项为期3年的赠款，用于操作CEDAR光学层析成像设施（COTIF）和对所获结果进行科学分析，其中COTIF的能力将应用于与稳定红色极光弧源有关的亚极光物理学的几个方面。 现在太阳活动极大期即将来临，1998年后期SAR弧的重新出现为研究SAR弧的体积发射率对纬度-高度的依赖性提供了第一次机会，这是获得依赖高度的激发物理学的唯一可能途径。 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得到解决。 为了进行后一项研究，PI建议使用CEDAR资助的高通量成像光谱仪（HITIES）。 合成孔径雷达弧机制的建模专门知识已经到位，质子建模方面的一位领先专家将加入该小组，作为另一个计划的一部分，这项工作的新内容是将COTIF和HITIES的成像科学能力应用于中层重力波的研究。 CEDAR博士后奖授予Steven Smith博士将允许从这些数据集研究波源和耗散机制。 随着新的FPI和LIDAR仪器被安装在Millstone Hill，用于CEDAR-TIMED合作，一套真正强大的光学诊断将最终到位，用于对极光下站点波活动的首次全面研究。建议延长一项为期3年的赠款，用于操作CEDAR光学层析成像设施（COTIF）和对所获结果进行科学分析，其中COTIF的能力将应用于与稳定红色极光弧源有关的亚极光物理学的几个方面。 现在太阳活动极大期即将来临，1998年后期SAR弧的重新出现为研究SAR弧的体积发射率对纬度-高度的依赖性提供了第一次机会，这是获得依赖高度的激发物理学的唯一可能途径。 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得到解决。 为了进行后一项研究，PI建议使用CEDAR资助的高通量成像光谱仪（HITIES）。 合成孔径雷达弧机制的建模专门知识已经到位，质子建模方面的一位领先专家将加入该小组，作为另一个计划的一部分，这项工作的新内容是将COTIF和HITIES的成像科学能力应用于中层重力波的研究。 CEDAR博士后奖授予Steven Smith博士将允许从这些数据集研究波源和耗散机制。 随着新的FPI和LIDAR仪器被安装在Millstone Hill，用于CEDAR-TIMED合作，一套真正强大的光学诊断将最终到位，用于对极光下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.
