re remain many interesting questions that can be effectively addressed, indeed uniquely addressed with these data. These ELBBO data can now be interpreted in a new light due to the availablility of new geophysical data sets during the balloon flights. In particular two electrodynamic data sets are available which will help determine the electrical coupling between the ground and the ionosphere. These data sets, which are presently available and on line, include a few weeks of overlapping balloon vector elecric field data from the Polar Patrol Balloons (PPB) and South Pole measurements of the vertical current density and electric field during most of the ELBBO flights (see support letter from E. A. Bering, III). Additionally we will coordinate our analysis with polar orbiting and geostationary weather satellite images (NOAA and GOES/GIMS data) and with solar terrestrial data about the magnetosphere (solar wind conditions and auroral current systems). This proposal is aimed at addressing
