This award will fund continued operation and discovery science with the incoherent scatter radar (ISR) at Massachusetts Institute of Technology (MIT)'s Millstone Hill (MH) Observatory (MHO). The ISR measures backscatter from ionospheric electrons, that is used to recover ion and electron temperatures, densities, winds and constituent abundances 100-1000 km above earth's surface. MHO has a very strong science education and community outreach component, and also curates and distributes an NSF community database.Research activities under this award include sub-auroral magnetosphere-ionosphere coupling; ionosphere-thermosphere coupling during geospace storms; long-term change in the ionosphere and thermosphere; whole atmosphere coupling; and meteoroid studies using software radar methods.The ISR is in the process of transitioning to a new, low cost digital architecture that will uniquely provide continuous, long-term, vertical profiles of ionospheric parameters. This new capability will substantially increase observations of ionospheric and thermospheric disturbances, and will be showcased over the period of performance of the award.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.

该奖项将通过马萨诸塞州理工学院（MIT）的Millstone Hill（MH）天文台（MHO）的不连贯的散布雷达（ISR）进行持续运营和发现科学资助。 ISR测量来自电离层电子的反向散射，用于恢复离子和电子温度，密度，风和成分丰度在地球表面上方100-1000公里。 MHO具有非常强大的科学教育和社区外展部分，还策划和分发了NSF社区数据库。该奖项的研究活动包括磁层磁层 - 离子层耦合；电离层 - 热球耦合在地球空中风暴中；电离层和热层的长期变化；整个气氛耦合； ISR正在使用软件雷达方法进行流星研究。在过渡到新的低成本数字体系结构的过程中，它将独特地提供电离层参数的连续，长期，垂直的曲线。这种新的能力将大大提高电离层和热圈干扰的观察结果，并将在奖项的绩效期间展示。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力优点和更广泛影响的审查标准通过评估来获得支持的。
