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.

ATM-0071836 Mendillo，Michaela Renewal的3年赠款，用于操作Cedar光学层析成像设施（COTIF），并提出了对获得结果的科学分析，其中COTIF能力将应用于与稳定的红色Auroral（SARRORAL）稳定性物理学有关的几个方面。 现在，太阳能最大值即将接近，1998年末，SAR ARC的重新表现为研究SAR ARC的体积排放速率的纬度高度依赖性提供了第一个机会，这是访问高度依赖性激发物理学的唯一可能方法。 现在可以解决热激发，高速对流激发和质子沉淀发射的增强问题。 为了进行后一项研究，PI提议将雪松资助的高通量成像 - 埃克尔光谱仪（HITE）验证。 为SAR ARC机制建模专业知识就位了，质子建模的领先专家将加入该小组，作为另一个程序的一部分。这项工作是在COTIF和HITIT上应用成像科学能力到中层重力波的研究。 史蒂文·史密斯（Steven Smith）博士将获得雪松博士后奖，将允许研究这些数据集中的波源和耗散机制。 在米尔斯通山（Millstone Hill）安装了新的FPI和LIDAR仪器进行雪松式合作的合作，最终将进行一组真正健壮的光学诊断，以在一个次生式场地进行波浪活动进行首次全面研究。 ATM-0071836 Mendillo，Michaela Renewal的3年赠款，用于操作Cedar光学层析成像设施（COTIF），并提出了对获得结果的科学分析，其中COTIF能力将应用于与稳定的红色Auroral（SARRORAL）稳定性物理学有关的几个方面。 现在，太阳能最大值即将接近，1998年末，SAR ARC的重新表现为研究SAR ARC的体积排放速率的纬度高度依赖性提供了第一个机会，这是访问高度依赖性激发物理学的唯一可能方法。 现在可以解决热激发，高速对流激发和质子沉淀发射的增强问题。 为了进行后一项研究，PI提议将雪松资助的高通量成像 - 埃克尔光谱仪（HITE）验证。 为SAR ARC机制建模专业知识就位了，质子建模的领先专家将加入该小组，作为另一个程序的一部分。这项工作是在COTIF和HITIT上应用成像科学能力到中层重力波的研究。 史蒂文·史密斯（Steven Smith）博士将获得雪松博士后奖，将允许研究这些数据集中的波源和耗散机制。 在米尔斯通山（Millstone Hill）安装了新的FPI和LIDAR仪器进行雪松式合作的合作，最终将进行一组真正健壮的光学诊断，以在一个次生式场地进行波浪活动进行首次全面研究。
