OUR PREVIOUS STUDIES OF THE ULTRA-LOW-FREQUENCY (ULF) WAVES IN THE MAGNETOSPHERE HAVE DISCOVERED SEVERAL PROPERTIES THAT WERE NOT KNOWN BEFORE AND STILL REQUIRE FURTHER INVESTIGATIONS. THE SPECIFIC TOPICS WHERE OUTSTANDING QUESTIONS REMAIN INCLUDE BUT ARE NOT LIMITED TO: THE GLOBAL POLOIDAL WAVES DURING GEOMAGNETICALLY QUIET TIMES THE DISCRETE FREQUENCIES OF POLOIDAL WAVES THE INTERPLAY BETWEEN POLOIDAL WAVES AND TOROIDAL WAVES THE DYNAMICS OF WAVE-PARTICLE INTERACTIONS AND THE CONNECTION TO THE GEOSPACE ENVIRONMENT. THIS FOLLOW-ON PROJECT CONTINUES THE ANALYSIS OF SPACE-BASED AND GROUND-BASED OBSERVATIONS OF ULF WAVES TO INVESTIGATE SOME OF THESE OUTSTANDING QUESTIONS PARTICULARLY STARTING TO ADDRESS THOSE RELATED TO THE CONNECTION TO THE GEOSPACE ENVIRONMENT. THE MAIN SOURCES OF DATA COME FROM THE FIELDS AND PARTICLE MEASUREMENTS FROM THE NASA MAGNETOSPHERIC MULTISCALE (MMS) MISSION AND THEY ARE SUPPLEMENTED BY THE DATA FROM OTHER HELIOPHYSICS MISSIONS AND GROUND-BASED MAGNETOMETER NETWORKS. THE PROPOSED TASKS CONSIST OF (1) THE DEVELOPMENT OF AN ALGORITHM FOR EFFICIENTLY IDENTIFYING ULF WAVE EVENTS IN SATELLITE MAGNETOMETER DATA AND (2) THE CONTINUATION OF THE DETAILED ANALYSIS OF POLOIDAL AND TOROIDAL ULF WAVES OBSERVED BY MMS SATELLITES AND GROUND-BASED MAGNETOMETER NETWORKS AS WELL AS THE SUPPORT FOR PUBLICATION. THE PROPOSED TASKS ARE PERFORMED BY THE PI AND A STUDENT ASSISTANT IN ONE YEAR.
