Middle Atmosphere Electrodynamics Using Stratospheric Balloons

ATM-9987684霍尔兹沃斯这是一个研究中层大气电动力学和大气层与电离层之间的耦合的建议。从1992年11月至1993年4月，使用平流层中的超压气球收集了关于大气电动力学的最广泛的数据集之一。这项名为ELBBO：延长寿命气球载天文台的实验，包括矢量电场和相关的电动力学测量，由国家科学基金会(授予大气8920428)和美国国家航空航天局联合赞助。总体而言，ELBBO实验非常成功，从5个有效载荷收集了高质量的数据，其中包括在这个高度(26公里)打破纪录的飞行时间。这项拟议的新工作的四个相关研究目标中的第一个与详细分析水平电场的新来源有关：这种新来源的证据现在已经在ELBBO数据集中找到。其他目标与其他中层大气电动力学问题有关，这些问题涉及局部可变性可以影响全球电路动力学的方式。此外，还将研究与中性大气的耦合以及磁暴对中层大气电动力学的影响。

ATM-9987684HolzworthThis is a proposal to study middle atmosphere electrodynamics and coupling between the atmosphere and ionosphere. From November 1992 through April 1993 one of the most extensive data sets on atmospheric electrodynamics was collected using superpressure balloons in the stratosphere. The experiment, called ELBBO: Extended Life Balloon Borne Observatories, included vector electric field and related electrodynamic measurements, and was sponsored jointly by the National Science Foundation (grant ATM 8920428) and by NASA. Overall the ELBBO experiment was very successful and collected high quality data from five payloads, and included record breaking flight duration at this altitude (26 km). The first of four related research goals of this proposed new effort has to do with a detailed analysis of the new source of horizontal electric fields: evidence of this new source has now been found in the ELBBO data set. Additional goals have to do with other middle atmosphere electrodynamics questions relating to ways in which local variability can effect global circuit dynamics. In addition, coupling to the neutral atmosphere and the influence of magnetic storms on middle atmospheric electrodynamics will be investigated.
