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

摘要 9317621 LaBelle该项目涉及敏感的无线电接收器在频率扫描模式从0.1 MHz到5.0 MHz的操作。 由此产生的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，加速导致极光的电子的机制。 该合同将继续支持已经在南极和美国南极计划自动地球物理观测站运行的接收器，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自动地球物理观测站。 此外，该项目还补充了位于阿拉斯加州两河镇北方极光区的一台类似仪器所产生的数据。 阿拉斯加项目得到了NSF大气科学部的支持。 对该项目的额外支持是由一个单独的总统青年研究员赠款的主要研究员。 PYI拨款的资金由大气科学部和极地计划办公室分配。 ***

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. ***
