There is still much to be understood about the processes contributing to relativistic electron enhancements and losses in the radiation belts. Wave particle interactions with both whistler and electromagnetic ion cyclotron (EMIC) waves may precipitate or accelerate these electrons. Using LANL Magnetospheric Plasma Analyzer (MPA) data from geosynchronous orbit, in conjunction with linear theory, we have developed a proxy for enhanced EMIC waves (Blum et al., 2009). We compare this proxy to in situ wave measurements from GOES high-resolution magnetometer data, and examine the presence of these waves as a function of both local time and storm epoch time. This enables broader understanding of the powerful applications of using plasma data to infer wave distributions in space.
