Development of static and dynamic models of the Earth's radiation-belt environment through the study of plasma waves, wave-particle interactions and plasma-number-densities from in-situ observations in the Earth's magnetosphere with the CRRES SPACERAD instruments. Scientific report No. 1, 22 Sep 90-30 Apr 91
This report describes the achievements of the first year of effort on data acquired by the University of Iowa/AFGL Plasma Wave Experiment (PWE) (AFGL 701-15 Plasma Sounder and AFGL 701-13-2 Search Coil Magnetometer) which was a part of the SPACERAD complement of instruments on the Combined Release and Radiation Effects Satellite (CRRES). The primary purpose of the PWE is to study plasma waves, wave-particle interactions, and plasma number densities in the radiation belts of the Earth's magnetosphere as observed by the CRRES SPACERAD instruments in order to provide essential parameters for understanding both the long-scale and short-scale temporal and spatial variations of the individual particle species and waves and their inter-relationships. Computer programs to display and analyze the CRRES PWE data from both the real-time data collected at CSTC (the U.S. Air Force's Consolidated Space Test Center at Onizuka AFB in Sunnyvale, CA) and the Agency Tapes have been developed and utilized to study the PWE data and to extract the electron number density throughout the CRRES orbit. Many significant new discoveries have been made including detailed observation of the fine structure in density variations and their association with enhanced low frequency electric field emissions, observations of deep cavities and ducts within the plasmasphere, and detection of multiple bands of emissions associated with multiple populations of energetic electrons.
