Understanding the coupling between atmospheric, ionospheric and magnetospheric electric fields and current systems is one of the basic goals of solar-terrestrial physics. Many radar techniques are used to study the high altitude thermosphere electric fields and their variations. New studies have shown the linkage between low altitude tropospheric and stratospheric electric fields and currents, with variations in the thermosphere. Development of techniques and acquisition of these low altitude data have been very controversial. This cooperative NSF and NASA project builds upon past operational programs and data analyses in the design of a multi-balloon long duration ( 3 months ) flight program to measure many of the needed parameters. The ELBBO ( Extended Life Balloon Borne Observations ) program plans to launch a total of ten balloons. Two prototype flights from Brazil and 8 others from either Brazil, New Zealand or the Antarctic depending somewhat on the outcome of the initial flights. The basic objectives are to measure the vector electric field, conductivity, current density, magnetic field,VLF and ULF electric and magnetic waves, nightglow variations and atmospheric x-rays. These data will then be used to test and improve existing models of the global electric circuit.

了解大气层、电离层 磁层电场和电流系统是 日地物理学的基本目标 许多雷达 技术被用来研究高空热层 电场及其变化。 新的研究表明， 低空对流层与平流层联系 电场和电流，随着 热层 技术的发展和这些技术的获取 低空数据一直是很有争议的。 这种合作 NSF和NASA的项目建立在过去的运营计划基础上， 多气囊长航时设计中的数据分析（3 几个月）的飞行计划，以测量许多所需的参数。 ELBBO（Extended Life Balloon Borne Observations） 计划总共发射十个气球。两架原型机 来自巴西，另外8名来自巴西、新西兰或 南极洲在某种程度上取决于最初的结果， 航班 基本目标是测量矢量电 场、电导率、电流密度、磁场、VLF和ULF 电磁波，夜光变化， 大气X射线 这些数据将用于测试和 改进现有的全球电路模型。
