WE WILL INVESTIGATE GLOBAL DISTRIBUTION PROPERTIES OF LONG-LASTING ULF WAVE TO DETERMINE THEIR SOURCE OF ENERGY. WE WILL USE A HIGH PARTICLE ENERGY RESOLUTION AT VAN ALLEN PROBES TO STUDY INTERACTIONS OF ULF MAGNETIC AND ELECTRIC FIELD PULSATIONS WITH ENERGETIC PARTICLES SUCH AS WAVE-PARTICLE RESONANCE MODULATION AND PARTICLE ACCELERATION. THE COMPLETION OF THESE PROPOSAL WILL PROVIDE SOME NEW INSIGHTS INTO THE GLOBAL DISTRIBUTION PROPERTIES OF ULF WAVE AND UNDERSTANDING ON HOW POPULATIONS OF RELATIVISTIC ELECTRONS AND IONS IN SPACE FORM OR CHANGE IN RESPONSE TO CHANGES IN SOLAR ACTIVITY AND THE SOLAR WIND AND HOW THEY HAVE AN INFLUENCE ON SPACE WEATHER.
