The Jicamarca Radio Observatory near Lima, Perú is a premier ground-based facility for studying plasma processes in the upper atmosphere near the magnetic equator. Jicamarca is celebrating its 60th anniversary this year. Over its life, it has undergone continuous renewal and so still represents the state of the art in radio technology in most respects. Some of the systems at Jicamarca are outdated, however, which impacts the scientific potential of the facility. The work will expand this potential by acquiring a final tube amplifier, replacing Jicamarca’s two tube-type driver amplifiers with modern solid-state units, upgrade the Jicamarca ionospheric sounder, and replacing an optical digital camera. The technical upgrades will improve the resilience and extend the lifetime of the observatory, while also dramatically enhancing its capabilities to enable new measurement modes. These will include a potentially transformative capability to directly probe the solar corona, an extension of topside and inner-magnetosphere measurements to 10,000 km from the current top limit of 6,000 km, and long-term measurements of plasma parameters. These, in turn, will provide novel ways to study equatorial plasma processes such as plasmaspheric refilling following solar and geomagnetic storms, formation of the equatorial spread F, and storm-time equatorial electrodynamics, as well as for operational space weather modeling and forecast purposes. Jicamarca has two highly successful educational programs such as the Jicamarca International Research Experience Program, a competitive program which is open to international (non-Peruvian) students, and a STEM program intended for Peruvian undergraduate students. The important broader impact of this project will be an enhancement of STEM educational opportunities through the provision of additional and novel research projects for the students and trainees. The additional capabilities and measurement modes will also provide new synergies with several satellite missions including the Constellation Observing System for Meteorology, Ionosphere, and Climate 2 and the Ionospheric Connection Explorer.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.

佩鲁在利马附近的Jicamarca无线电天文台是一家主要的地面设施，用于研究磁性等方面的高层大气中的血浆过程。 Jicamarca今年将庆祝其成立60周年。在其一生中，它经历了持续的续签，因此在大多数方面仍然代表无线电技术的最新状态。但是，Jicamarca的某些系统已过时，这影响了该设施的科学潜力。工作将通过获取最终管放大器来扩大这种潜力，从而用现代的固态单元代替Jicamarca的两个管型驱动器放大器，升级Jicamarca Ionosphere Sounder，并取代光学数码相机。技术升级将提高弹性并延长观察的寿命，同时也大大提高了其能力以实现新的测量模式。这些将包括直接探测太阳电晕的潜在变革能力，从当前最高限度的6,000 km的顶部和内部磁层测量延伸至10,000 km，以及血浆参数的长期测量。反过来，这些将提供新的方法来研究等分等离子过程，例如太阳和地磁暴风雨后平原的水平均填充，等效性扩散F以及风暴时间等效性电动力学以及操作空间空间天气建模和预测目的。 JICAMARCA拥有两个非常成功的教育计划，例如Jicamarca国际研究经验计划，一项竞争性计划，向国际（非佩鲁维亚）学生开放，以及针对秘鲁本科生的STEM计划。该项目的重要广泛影响将是通过为学生和受训者提供其他新颖的研究项目来增强STEM教育机会。其他功能和测量模式还将为新的协同效应提供多个卫星任务，包括气象学，电离层和气候2和Climate 2和Ionsphere Connection Explorer的星座观察系统。该奖项反映了NSF的法规任务，并认为通过基金会的知识优点和广泛的criperia criperia criperia criperia criperia the Insportaution the Pociess cripation。
