Abstract
The results of a high-altitude probing experiment are presented which demonstrate the capability of measuring atmospheric stability at tropopause altitudes using a 940-MHz forward-scatter CW radar system. Vertical profiles of the potential temperature gradient measured by radiosondes launched under the common volume of the radar system are well correlated with profiles of received power from radar data, taken nearly simultaneously. Thus, the tropopause can be located within a few hundred meters and its stability structure can be observed as it evolves.
