LF/MF/HF Radio Observations from a Southern Hemisphere Auroral Zone Site

摘要9317621拉贝尔这项计划涉及以0.1兆赫兹至5.0兆赫兹扫频模式运作的灵敏无线电接收器。由此产生的光谱将被用于研究磁层和电离层中产生无线电波的物理机制，例如，加速产生极光的电子的机制。该合同将继续支持已经在南极和美国南极计划南极自动地球物理观测站运行的接收器，还将支持另外两个接收器的建造和运行，这两个接收器将安装在南极的英国南极调查自动地球物理观测站。此外，该项目补充了位于阿肯色州两河北部极光地带的类似仪器所产生的数据。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。对该项目的额外支持由总统向首席调查员提供的另一笔青年调查员补助金提供。PYI拨款的资金由大气科学部和极地项目办公室平分。***

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. ***
