A Comparison of Solar Wind Parameters Measured by IMP 8, Voyager 1 and Voyager 2

Abstract

This thesis analyzes measurements of four solar wind parameters (radial velocity, density, ram pressure, and flux density) as observed by three spacecraft: IMP 8 (Interplanetary Monitoring Platform 8, also called Explorer 50), Voyager 1, and Voyager 2. First, a brief discussion of the evolution of the solar wind within the solar system is presented in order to establish a basis for understanding observed trends in spacecraft data. Then following is an explanation and comparison of the data gathering instruments and collection methods of IMP 8 and the Voyager spacecraft including a discussion of the data analysis. Next, solar wind parameters are compared over four averaging periods: 25/27 days, representing the period of one solar rotation as seen by the Voyagers/IMP 8; 50/54 days, to coincide with two solar rotations; 100 days and 200 days, approximating four and eight solar rotations, respectively. Similarities and differences between spacecraft observations are discussed.
