Abstract 9317621 LaBelle This project involves the operation of sensitive radio receivers operating in a frequency-swept mode from 0.1 MHz to 5.0 MHz. The resulting spectra will be used to study the physical mechanisms in the magnetosphere and ionosphere which are responsible for the radio waves, for example, the mechanisms which accelerate the electrons which cause aurora. This award will continue support for the receivers already operating at South Pole and in the U.S. Antarctic Program Automatic Geophysical Observatories in Antarctica and will also support the construction and operation of two more receivers which will be installed in British Antarctic Survey Automatic Geophysical Observatories in Antarctica. Also, the project complements the data being produced by a similar instrument which is located in the northern auroral zone at Two Rivers, AK. The Alaska project is supported by the Atmospheric Sciences Division of NSF. Additional support for this project is provided by a separate Presidential Young Investigator grant to the Principle Investigator. Funding for the PYI grant is split between the Division of Atmospheric Sciences and the Office of Polar Programs. ***

摘要 9317621 LaBelle 该项目涉及以 0.1 MHz 至 5.0 MHz 扫频模式运行的敏感无线电接收器的操作。 所得光谱将用于研究磁层和电离层中产生无线电波的物理机制，例如加速电子从而产生极光的机制。 该合同将继续支持已在南极和美国南极计划南极洲自动地球物理观测站中运行的接收器，并将支持另外两个接收器的建造和运行，这些接收器将安装在英国南极调查局南极洲自动地球物理观测站中。 此外，该项目还补充了位于阿拉斯加州两河北极光区的类似仪器产生的数据。 阿拉斯加项目得到了美国国家科学基金会大气科学部的支持。 该项目的额外支持由总统青年研究员向首席研究员提供的单独拨款提供。 PYI 赠款的资金由大气科学部和极地项目办公室分配。 ***
