Analysis of X-Ray and Related Data from the South Pole Balloon Campaign

这笔赠款将支持继续分析1985-86年南方夏季从南极洲南极站放飞的一系列气球上的极光x射线探测器所获得的数据。该实验是与休斯顿大学联合进行的。探测到的x射线是由高能电子产生的，这些电子从磁层沉淀到上层大气中。这些数据将与休斯敦大学小组在同一气球上测量的电场数据以及许多地面仪器的数据相结合进行分析，这些仪器包括马里兰大学的测速计、贝尔实验室和新罕布什尔大学的磁力计以及在拉布拉多的鹅湾和格陵兰岛的森德雷斯特罗姆的共轭雷达。此外，这些数据将与现有的航天器数据进行比较，以确定高能极光电子沉淀发生的条件。马里兰大学和提案人都准备好了开展这项研究。

This grant will support the continuation of the analysis of data obtained from auroral x-ray detectors that were flown on a series of balloons that were flown from the South Pole Station, Antarctica during the austral summer of 1985-86. The experiment was done in conjunction with the University of Houston. The x-rays that were detected were produced by energetic electrons that were precipitated into the upper atmosphere from the magnetosphere. The data will be analyzed in conjunction with electric field data measured on the same balloons by the University of Houston group as well as with data from a number of ground based instruments such as the University of Maryland riometers, the Bell Labs and University of New Hampshire magnetometers and the conjugate radars at Goose Bay, Labrador and Sondrestrom, Greenland. In addition the data will be compared with the available spacecraft data to determine the conditions under which energetic auroral electron precipitation occurs. The University of Maryland and the proposers are well equipped to carry out this research.
