THE GOAL OF THE STUDY IS TO BETTER UNDERSTAND HOW TURBULENCE IS CREATED AND DRIVEN IN DIFFERENT REGIONS IN GEOSPACE, THE SCALE LENGTHS INVOLVED,AND THE DISSIPATION MECHANISMS AT WORK. THE STUDY WIN LOOK AT TURBULENCE IN THE SOLAR WIND, MAGNETOSHEATH, PLASMASHEET AND CUSP. THIS IS PRIMARILY A DATA BASED STUDY USING ELECTRON DATA FROM THE 4 CLUSTER SPACECRAFT. THE ELECTRON DATA SETS ANOW FOR THE COMPUTATION OF VOLUMETRIC PARAMETERS,NAMELY THE DIVERGENCE (COMPRESSION) AND CURL (VORTICITY). FROM THESE A NUMBER OF PARAMETERS, SUCH AS THE TAYLOR MICROSCALE AND KINEMATIC VISCOSITY CAN BE DIRECTLY COMPUTED WITH A 4 SECOND RESOLUTION (THE SATELLITE SPIN PERIOD). THESE PARAMETERS ARE USED TO DESCRIBE THE TURBULENCE AND TO INVESTIGATE ITS PROPERTIES. TO OUR KNOWLEDGE THIS IS THE FIRST ATTEMPT AT COMPUTING AND USING VOLUMETRIC PLASMA PARAMETERS. AS SUCH PART OF THE PROPOSAL WILL CONSIST IN UNDERSTANDING THE SIGNATURES SEEN IN THE PARAMETERS AND THE SOURCE OFTHE SIGNATURES. THE PROPOSED STUDY IS RELEVANT TO NASA IN TWO RESPECTS: IT MESHES WITH THE NASA OVERALL NEAR TERM GOAL OF UNDERSTANDING "ENERGY CONVERSION AND TRANSFER, CROSS-SCALE COUPLING, TURBULENCE AND NONLINEAR PHYSICS"; AND IT LAYS OUT A FRAMEWORK FOR FUTURE ANALYSIS WHICH CAN BE ADOPTED BY UPCOMING MULTIPOINT MISSIONS SUCH AS MAGNETOSPHERIC MULTISCALE. IT WILL ALSO SHOW AREAS WHERE IMPROVEMENTS IN MEASUREMENT TECHNIQUES WILL RESULT IN IMPROVED RESULTS.
