The 2017 eclipse observations by the Airborne InfraRed Spectrometer (AIR-Spec) demonstrated that thermal infrared (IR) imaging spectroscopy is possible from the NCAR's HIAPER GV platform. This opened a new window of opportunity for high resolutions thermal IR spectroscopy of the Sun's corona on a platform that avoids the vast majority of the atmospheric absorption. The 2017 AIR-Spec eclipse observations revealed all of the target coronal emission lines at several coronal positions, showed Hydrogen lines in the prominence observations and captured the chromospheric flash spectrum.This three-year project is intended to re-fly the AIR-Spec instrument during the 2019 July 2 total solar eclipse in the south Pacific off the coast of Chile. During this project, the AIR-Spec will be upgraded to have an improved sensitivity, image stability, and automation of the data collection process. The goal is to characterize the thermal IR emission of Sun's corona, including an investigation of numerous coronal IR emission lines, across a variety of solar structures (coronal holes, plumes, prominences, etc.) on an otherwise almost unexplored physical regime. The project's primary personnel are two very early-career women (one scientist, one engineer), and additional REU students will be involved -- including for the flight preparations themselves. The project team is committed to fostering diversity and inclusion while training the next generation of instrumentation scientists and engineers in the U.S. The first AIR-Spec flight succeeded in measuring all targeted five infrared (IR) coronal emission lines, including the first-of-its-kind measurement of the coronal Fe IX line at 2.845 microns. The re-flight of AIR-Spec during the 2019 solar eclipse will allow the project team to focus on the detailed characterization of various emission lines in different conditions of the Sun's corona. The upcoming AIR-Spec experiment will exercise a different capability of the NCAR's GV aircraft. Namely, the IR transmissive window will be mounted on a side portal adjacent to the optical bench. In doing so, the project team will demonstrate the flexibility of the design, simplify the operations and verify their ability to observe eclipses anywhere in the world. Developing the ability for coordinated observations of the Sun's corona with the future DKIST will be greatly beneficial for the calibration of DKIST observations, and it will motivate future solar instrumentation. The research and EPO agenda of this project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

机载红外光谱仪 (AIR-Spec) 进行的 2017 年日食观测表明，NCAR 的 HIAPER GV 平台可以实现热红外 (IR) 成像光谱。 这为在避免绝大多数大气吸收的平台上对太阳日冕进行高分辨率热红外光谱分析打开了新的机会之窗。 2017 年 AIR-Spec 日食观测揭示了多个日冕位置的所有目标日冕发射线，显示了日珥观测中的氢线，并捕获了色球闪光光谱。这个为期三年的项目旨在重新飞行 AIR-Spec 仪器2019 年 7 月 2 日，智利海岸南太平洋发生日全食。 在此项目期间，AIR-Spec 将进行升级，以提高灵敏度、图像稳定性和数据收集过程的自动化。 目标是表征太阳日冕的热红外发射，包括在几乎未经探索的物理状态下对各种太阳结构（日冕洞、羽流、日珥等）的众多日冕红外发射线进行研究。 该项目的主要人员是两名职业生涯早期的女性（一名科学家，一名工程师），其他 REU 学生也将参与其中，包括自己进行飞行准备工作。 该项目团队致力于促进多样性和包容性，同时培训美国下一代仪器科学家和工程师。第一次 AIR-Spec 飞行成功测量了所有目标五条红外 (IR) 日冕发射线，包括其第一条- 2.845 微米处的日冕 Fe IX 线的实物测量。 AIR-Spec 在 2019 年日食期间的重新飞行将使项目团队能够专注于太阳日冕不同条件下各种发射线的详细表征。 即将进行的 AIR-Spec 实验将锻炼 NCAR GV 飞机的不同能力。 即，红外透射窗口将安装在邻近光具座的侧门上。 在此过程中，项目团队将展示设计的灵活性、简化操作并验证他们在世界任何地方观测日食的能力。 发展与未来DKIST协调观测太阳日冕的能力，将极大有利于DKIST观测的校准，并将推动未来太阳仪器的发展。 该项目的研究和 EPO 议程支持 AGS 部门在发现、学习、多样性和跨学科研究方面的战略目标。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响进行评估，被认为值得支持审查标准。
