oa Tropospheric and Stratospheric Conductivity Measurements in Brazil

Conductivity measurements were carried out during a balloon flight launched from Cachoeira Paulista, Brazil (22°44' S, 44°56' W) on Jan 26, 1994. For the first time negative and positive conductivity profiles with altitude were obtained in Brazil. Along its trajectory the balloon passed over three thunderstorms, as identified by video on-board images. The data give an unique opportunity to study the stratospheric conductivity variations.
