Middle Atmosphere Electrodynamics Using Stratospheric Balloons

ATM-9987684 Holzanche这是一个研究中层大气电动力学和大气与电离层耦合的建议。 从1992年11月至1993年4月，在平流层使用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。 这个实验叫做ELBBO：延长寿命的气球载观测站，包括矢量电场和相关的电动力学测量，并由国家科学基金会（拨款ATM 8920428）和美国航天局联合赞助。 总的来说，ELBBO实验是非常成功的，从五个有效载荷收集了高质量的数据，包括在这个高度（26公里）的破纪录飞行时间。 这项新研究的四个相关研究目标中的第一个是对水平电场的新来源进行详细分析：现在已经在ELBBO数据集中发现了这种新来源的证据。 其他目标与其他中层大气电动力学问题有关，这些问题与局部变化影响全球电路动态的方式有关。 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.
