Balloon-Borne Observations of Sprites and Jets, NAG5-5126PI.: Edgar A. Bering, III, Physics Department, University of HoustonRe: Statement of WorkYear 2, January 1, 1998 to December 31, 1998In year 2 of this project we will complete building three balloon payloads as described in the proposal. These payloads will contain 3 axis electric and magnetic field detectors, conductivity and electric current sensors and X-ray detectors as described in the proposal. We will also prepare 6 sets of booms and input pre-amplifier boards, to enable real-time refurbishing of the payloads for immediate reflight. We will also calibrate and environmentally qualify these payloads. During the summer of year 2 of the project, these balloons will be flown from a location to be selected in thecentral Great Plains. The anticipated campaign strategy will depend on real time predictions of sprite producing mesoscale convective complex activity from campaign headquarters with input from Yucca Ridge Observatory in Colorado, followed by a late evening launch. We expect to launch from base airports in the western Iowa during July and August. Cut-down and recovery will take place east of the Front Range. Real-time field refurbishment for reflight should then enable us to make six flights. Given the vagaries of weather prediction, perhaps half of these will get close enough to a sprite producing mesoscale convection complex to provide useful data. The second half of year 2 will be devoted to reduction, analysis and interpretation of the data. |
