Ions, which transfer energy between our atmosphere and space, are responsible for electric current heating, however, these measurements are difficult to make, and are sparse as a result. Historically, we have used ground based radar to make educated guesses about how intensely these ions are heating the atmosphere, but making measurements using rockets that physically enter the area of interest will allow us to significantly increase the accuracy of our data. Using the ACES-II(Aurora Current and Electrodynamics Structures) sounding rocket, we made these ion measurements, analyzed them, and corrected them to study energy transfer. We removed anomalies in our data, which arose due to the issues associated with sounding rocket measurements, such as spinning, increased ion energies, and spikes in ion counts due to the supersonic rocket motion. After correcting these issues, we examined agreements, in various aspects, with expected ion heating trends.
