During several recent NASA rocket missions flown to study Earth's upper atmosphere, small devices called 'dropsondes' have been ejected from the main rocket payload to obtain scientific measurements at different points in space along the flightpath of the rocket. In this work, we present observational data collected by these dropsondes for two sounding rocket missions that flew through vertically narrow regions of enhanced plasma density called 'Sporadic E layers'. We analyze these measurements and combine them with simulation results to better understand the physical processes which govern the behavior of Sporadic E.
