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.

该奖项将资助马萨诸塞州理工学院（MIT）的Millstone Hill（MH）天文台（MHO）的非相干散射雷达（ISR）的持续运行和发现科学。ISR测量电离层电子的后向散射，用于恢复地球表面100-1000公里以上的离子和电子温度、密度、风和成分丰度。MHO有一个非常强大的科学教育和社区外展组成部分，还管理和分发NSF社区数据库，该奖项下的研究活动包括极光磁层-电离层耦合;地球空间风暴期间的电离层-热层耦合;电离层和热层的长期变化;整个大气层耦合; ISR正在过渡到一种新的、低成本的数字结构，这种结构将独特地提供电离层参数的连续、长期、垂直剖面。这一新的能力将大大增加电离层和热层扰动的观测，并将在该奖项的执行期间得到展示。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
