空间天气（Space Weather）活历史：Donald Fairfield 博士

Space Weather Living History: Dr. Donald Fairfield

节目 | 6-12+ 年级 | 在本次访谈中，Don Fairfield 博士回顾了他自 20 世纪 60 年代初开始的磁层物理学开创性职业生涯。在导师 James Dungey 博士的指导下，Fairfield 利用早期卫星（satellite）数据证明了向南的行星际磁场（interplanetary magnetic field）驱动了磁层电流。在加入美国国家航天局（NASA）戈达德太空飞行中心后，他利用 IMP 航天器数据在空间天气领域做出了一系列基础性发现。

Show | Grades 6-12+ | In this interview, Dr. Don Fairfield recounts his pioneering career in magnetospheric physics, beginning in the early 1960s. Working under his advisor Dr. James Dungey, Fairfield used early satellite data to prove that the southward interplanetary magnetic field drives magnetospheric currents. After joining NASA Goddard, he utilized IMP spacecraft data to make several foundational discoveries in space weather. His key contributions include mapping the Earth's magnetopause and bow shock, discovering the "foreshock" region, and co-creating the first quantitative model of the Earth's distorted magnetic field. He also helped explain the "polar rain" phenomenon and how solar wind interacts with the magnetosphere.

他的主要贡献包括绘制地球（Earth）磁层顶和弓形激波（bow shock）的图谱，发现“前激波”区域，并共同创建了首个地球畸变磁场（magnetic field）的定量模型。他还协助解释了“极雨”现象以及太阳风（solar wind）如何与磁层相互作用。
